Here is how our last tournament debutants did:

Agōra handled his makushita debut about as well as could reasonably be expected given his background and late start. He secured enough wins to remain competitive without ever looking overmatched. There were clear limitations in speed and adaptability against sharper technicians, He will need more experience to hold his own against makushita level opponents, something he will gain via a drop back to Sandanme for Natsu 2026. He defeated fellow rookie Yabugasaki, but lost to Gōhakuun.

Okada’s first makushita appearance was uneven but informative.His style produced early momentum in some matches, particularly when he was able to dictate terms at the tachiai, but more experienced opponents exposed his relative lack of polish once initial attacks stalled. He managed to defeat the Shikoroyama-beya prospect Tenrōsei, and fellow rookie Yabugasaki. He can expect a small jump up the banzuke.

After three straight kachi‑koshi earned his promotion, Gōhakuun just snuck in to Makushita at the bottom rank (60 West). He finished with a losing record and will be back in Sandanme for Natsu. His first victory was a fusen, and even with that he started 1-3. He managed a small comeback, defeating two in a row (including Agōra) before losing to Fudōhō in is last bout., The slide back should provide another opportunity to rebuild momentum.

Yabugasaki finished 2-5, with losses to Okada and Agōra. He also was unable to defeat Tenrōsei. It appeared that he was not yet able to match the speed and strength of his opponents or control his bouts consistently.

I am taking a small time-out here, as there were some questions raised as to why I did not really rank Yabugasaki as a sekitori prospect, despite his rapid ascent up the rankings. There were questions as to how I decided to lump in his chances with those of Okada. Let’s just say that there is little statistical underlying my assessments. It is more of a feeling of how I think each wrestler will progress given the bouts that I have seen and their pedigree.

In this case, Yabugasaki is not a “cream of the crop” high school talent. Many of these high schoolers who are not in the elite tend to peak in mid-to upper makushita unless they make some serious changes. In the matches I saw earlier in his career, he just did not have the “special something” that I see in some real talents. I am happy to be proven wrong. Please remember that my grading style is more of an art form than a science (and I have no official border lines between my subjective judgement calls) and that lots can happen in sumo to alter the trajectory of a career. Anyway, back to Sandanme with Yabugasaki for Natsu.

Ryūhō had a higher debut and started with a 4-0 streak before finishing 5-2. His makushita debut further reinforced his status as one of the sport’s elite young prospects. He carried over the maturity and balance that defined his lower‑division run, dispatching experienced opponents with calm grip work and disciplined ring sense. He lost to Sandanme champ (and former sekitori) Nabatame and former Sandanme champ Daimasakari. However, he defeated some high-school prospects (Fujinoyama and Anōshō) as well as former sekitori Kaishō. Unlike the others on this list, he competed quite consistently and convincingly in Makushita and will be in the top half of the division in Natsu. Among this group, he emerged as the clearest near‑term sekitori candidate.

Kinoshita, who received the shikona of Fudōhō (不動豊) got his winning record on the last day against Gōhakuun. He had a bit more trouble against the borderline Makushita/Sandanme wrestlers than would normally be expected of a Makushita Tsukedashi with such a university pedigree His bouts did not show that he was overly ranked, but with wins and losses against opponents of a similar depth, I can say that it was a bit of a disappointing debut. A jump toward the top of makushita will happen as he gains professional seasoning. His shikona was given my his master, intended to convey an “unshakable heart” and with the 豊 coming from the stable’s naming convention. The Fudō is “immovable” or steadfast and is often associated with a symbolizing Buddhist resolve and discipline.

Onto the Natsu 2026 Makushita rookies (and a bonus catch-up):

Kōseiryū (光星竜)

Stable: Otowayama
Age: 25
Height (cm/feet-inches): 174 / 5’8”
Weight (kg/lbs): 125 / 275
Home prefecture: Tokyo
High School: Yasuda Gakuen
University: University of Nevada
Career Record and notes: 29-8-5 (.784)
Debut: Hatsu 2025
Notes: Jonidan Yūshō in January 2026
Father is former Maegashira Akinoshū
Possibility of reaching sekitori: I’ll say likely, as it would make a great story.

Kōseiryū has a rather unconventional background and atypical pathway into professional sumo. He is the eldest son of former top-division wrestler Akinoshū (安芸ノ州). However, sumo was not at the forefront of his activities for much of his life. Instead, he excelled in jūdō and his studies, going so far as to get a degree in aerospace engineering in Nevada. In other words, he seemed closer to being a rocket scientist than a master of the dōhyō.

Apparently, he was greatly cherished by his father’s senior stablemate Terao, who was so delighted at Kōsei’s birth that he named him, and even celebrated it as if he were his own child. Despite growing up in the sumo world, he took his competitiveness onto the jūdō mat and became known on the national level – placing third in the National Junior Championships while in 4th grade (only losing to a future Olympic silver medalist). He excelled during his time at Yasuda Gakuen Middle and High School (the alma mater of Terao). He moved to the US and managed to balance his engineering studies.

He first enrolled at Orange Coast College, a community college in Costa Mesa, California where he studied aerospace engineering, served as the president of the Japanese Student Association. In 2022, he won the National Collegiate Judo Championship and the U.S. Open Judo Championships. After graduating from Orange Coast College, he transferred to the University of Nevada to complete his aerospace engineering degree. His goal was to work in rocket manufacturing. He was invited to join the U.S. national judo team, but he declined because it would have required changing his nationality.

The turning point for him came in 2023 when former Sekiwake Terao passed away. Terao had been a great friend of his father, and supposedly helped to even name the newborn Kōsei.. Before his death, Terao supposedly said “I wish I could have seen you in a mawashi” and those words weighed heavily on Kōseiryū as he approached the sumo entrance age limit. He dipped his toes into sumo during the 2024 U.S. Sumo Open, where he finished second in the light heavyweight division.

As the Sumo Association had just allowed inexperienced individuals under 25 to join (after taking a special physical ability test), he quit the US Judo circuit and joined the new Otowayama stable under Kakuryū. Kakuryū belonged to Izutsu stable, the same as Terao and his father. He took the shikona Kōseiryū as a way to honor Terao (by using his given name) and combining it with the dragon (ryū) from his stablemaster. His younger brother attends Chuo University where he is a member of the school’s sumo club.

He describes his sumo as an application of his physics education – applying leverage, balance, center of gravity, and timing to compensate for his lack of traditional sumo training. He favors jūdō-like throws and counters. Following an injury that knocked him back to jonidan, he took the yūshō (despite cracking the middle finger on his left hand on Day 1) and rocketed up the rankings. His promotion to makushita will mark a great test of his abilities against some seasoned vets and upcoming prospects.
His hobbies include surfing, golf, baseball, stargazing, building LEGO Star Wars sets, watching comedy, and appreciating art.

Kasshō (滑翔)

Stable: Yamahibiki
Age: 23
Height (cm/feet-inches): 176 / 5’9”
Weight (kg/lbs): 136 / 300
Home country: Hyōgō
High School: Tsushima High
University: —
Career Record and notes: 110-87-13 (.558)
Debut: 2021 Haru
Notes: None
Possibility of reaching sekitori: Very unlikely

Another name to watch as he settles into the makushita ranks is Kasshō, a Hyōgo native whose rise has been closely followed back home. Hailing from Shinonsen Town (Hamasaka area), Kasshō is celebrated locally as part of a rare trio of active professional rikishi produced by the same small community, alongside Gōhakuun of Takekuma stable (see last post about shin-makushita for Haru 2026) and Daishōki of Oitekaze.

Kasshō’s sumo roots were planted at Hamasaka Junior High School, where he was already active in the sport before moving on to Tsushima High School, a program known for steady national‑level participation. He became a key member of the sumo team, performing well enough in inter‑high and national tournaments to get on the radar of professional scouts. Sumo is very much a family affair as well – his younger sisters (one a university sophomore and the other a high‑school freshman) are both active members of their respective school sumo clubs.

His sumo career came full circle during a spring jungyō two years ago, when Kasshō returned to his old high school while touring as a professional. For a wrestler still early in his career, the visit symbolized both how far he had already come. He started his career with some very good results in 2021-2022, despite missing two tournaments with injury. He was in Sandanme in less than two years from his debut. It took some time for him to settle into the division, where he had been since Haru 2024. He finally settled into the top half of the division in mid-2025 and on the back of two 5-2 records will enter Makushita.

His shikona means to glide (if you look at it on Google, you will see lots of images of hang-gliding). It could also be interpreted as “moving smoothly and effortlessly” and was likely given to him by his stable master as a sort of objective. Additionally, the shikona uses a part of his first name, Hishō.

Honoikazuchi (火雷)

Stable: Ikazuchi
Age: 22
Height (cm/feet-inches): 191 / 6’3”
Weight (kg/lbs): 166 / 365
Home prefecture: Kanagawa
High School: Mukainooka Technical High
University: Nippon Sports Science University
Career Record and notes: 0-0-0 (.000)
Debut: 2026 Natsu, Makushita Tsukedashi
Notes: None

Possibility of reaching sekitori: Quite likely

One of the more intriguing new faces to reach makushita is Bill Christopher Lee, a Kawasaki native whose development reflects both a long athletic arc. Growing up, Lee split his time between basketball and karate before committing to sumo at the Kawasaki Sumo Club during elementary school. By high school, his physical gifts were already evident: standing 191 cm, he attended Kanagawa Prefectural Mukonooka Technical High School, a program with deep sumo credentials (and lots of recruits in Futagoyama stable).  He helped the team to a third‑place finish at the Inter‑High, putting him as a top level university recruit.

Lee’s true breakthrough came after being recruited to Nippon Sport Science University (NSSU), where the club’s legendary director helped him to use his raw power and develop his own style. Despite his size, Lee was intentionally steered away from reactive or tentative sumo and instead drilled relentlessly in forward‑moving oshi‑sumo, a transformation that paid dividends. By his sophomore year, he finished third at the All Japan Student Sumo Championships, and as a senior he emerged as the team’s captain.

His senior year at NSSU capped his amateur career. Lee finished runner‑up at the National Sports Festival and added another strong finish (3^rd place) at the All‑Japan Student Championships. These performances earned him the makushita tsukedashi eligibility. Long an admirer of former NSSU sumo club legend, Ōnosato, Lee has noted that his goal has evolved from simply looking up to the yokozuna to one day testing himself directly against him. Lee enters makushita as a physically imposing, purpose‑built prospect whose ceiling will be measured by how quickly that forward pressure translates against seasoned professional opposition. On April 17, it was announced that his shikona is Honoikazuchi (火雷), with the latter character coming from the stable name.

Despite his English sounding legal name (a result of his mixed heritage), he was born and raised in Japan and will not count as a foreign rikishi. Ikazuchi-beya already has its foreigner slot occupied by the Ukrainain, Shishi.

Ōmori (大森)

Stable: Oitekaze
Age: 22
Height (cm/feet-inches): 185 / 6’0”
Weight (kg/lbs): 120 / 264
Home prefecture: Ishikawa
High School: Kanazawa Gakuin High
University: Kanazawa Gakuin University
Career Record and notes: 0-0-0 (.000)
Debut: 2026 Natsu, Makushita Tsukedashi
Notes: ..

Possibility of reaching sekitori: Quite likely

Ōmori enters grand sumo with a Strong amateur background.  From Ishikawa prefecture, he began sumo in the first grade inspired by watching the legendary Chiyonofuji with his father. He continued with sumo through elementary school, but then quit during middle school to join the baseball club. 

At the end of middle school, he resolved to return to sumo and “become strong”. He left his hometown to live in the dorm at Kanazawa Gakuin High School. By the time he was a junior, he had become a national level contender in tournaments, finishing as runner-up in both individual and team competitions at the Inter-High High School Championships and the Kanazawa High School Sumo Tournament. He proceeded up the direct pipeline from the attached high school to Kanazawa Gakuin University.

As a freshman, he won the West Japan Rookie title. As a Junior, he won the individual and team championships at the 78^th National Sports Festival in Saga. Suffering from a dislocated shoulder as a senior (one that required surgery), he was still 2^nd at the All-Japan Sumo Championships. This earned him the coveted makushita tsukedashi status he now takes advantage of.

He is quite lighter than many others coming in via the tsukedashi route, with his sumo built on speed, balance, and forward pressure. His technical grounding and versatility should enable him to make an immediate impact on the dohyo. He was persuaded to go professional though his hometown ties to Kitajin Oyakata (former Endō) and has expressed a desire to represent his earthquake-impacted hometown on the national stage. Like Kaki, he is likely an uchi-deshi of Endō and may branch out, should Kitajin decide to open his own stable. There has not yet been any media reporting of a proper shikona and my feeling is that he will start under his family name.

Gōnoshō (豪ノ勝)

Stable: Takekuma
Age: 20
Height (cm/feet-inches): 189 / 6’2”
Weight (kg/lbs): 144 / 318
Home prefecture: Saitama
High School: Saitama Sakae High School
University: – –
Career Record and notes: 36-20-0 (.643)
Debut: 2024 Kyushu
Notes: Brother is Gōseiryū

Possibility of reaching sekitori: Unlikely

Gōnoshō is a steadily developing rikishi from Aomori prefecture, who has followed his elder brother, Gōseiryū, into sumo. He began sumo at age four, influenced by his older brother. He continued through school, appearing in elementary, middle, and high school All-Japan tournaments.

He attended powerhouse Saitama Sakae High School (which is the fishing grounds for former alumn Takekuma Oyakata). Under his high school coach, he developed a technically grounded style that heled his team win the Kantō High School Championship and qualify the team for the Inter-High. Individually, he finished in the top eight at the All-Japan High School Tournament and the top 16 at the National Sports Festival (Kokutai). This reveals that he is a competitive prospect, but not quite the level of a breakout star.

Many college recruits tried to lure him to their programs, including NSSU and Nihon University. Nevertheless, he opted to become pro right after high school on advice from his father that he would develop quicker and more rounded through regular professional keiko rather than amateur competition. He selected Takakuma stable, to join his brother. He had also been impressed by Takekuma’s training regime during his visits.

He has made steady progress through the lower divisions. He made it to mid-Sandanme before his first make-koshi. His 6-1 record in March from Sandanme 44 was a nice breakout tournament that earned the promotion to Makushita. At this point in his career, Gōnoshō is a clear yotsu‑zumo specialist, favoring belt engagement over extended pushing exchanges. He shows a preference for a right‑hand inside grip and forward‑moving sumo, with yorikiri as his most common winning technique. Gōnoshō already possesses the size expected of a future sekitori, but his career profile to this point suggests a longer‑horizon development path rather than an immediate rise. His Shikona from oyakata, his first name, and 豪ノ勝 literally means “mighty victory” or “victory through strength.”

Tatsubayama (龍葉山)

Stable: Tokitsukaze
Age: 20
Height (cm/feet-inches): 189 / 6’2”
Weight (kg/lbs): 153 / 336
Home prefecture: Ulaanbaatar, Mongolia
High School: Meitoku Gijuku High School
University: —
Career Record: 23-3-2 (.885)
Debut: Natsu 2025
Notes: Jonokuchi Yūshō Nagoya 2025

Possibility of reaching sekitori: I believe so, from what I have seen so far – provided injuries do not derail him

Born in Ulaanbaatar, Mongolia, as Buyantogtokh Munkh‑Erdene, Tatsubayama began athletic training in Mongolian wrestling (Bökh) as a child. That background provided a natural foundation for his eventual transition to Japanese sumo. Tatusbayama was scouted at age 15 and moved to Japan to attend Meitoku Gijuku High School, one of the strongest amateur sumo programs in the country and famously the alma mater of Yokozuna Asashōryū. He became a regular presence on the national stage. During his high‑school career, he appeared in major tournaments, steadily building experience against elite domestic competition.

In his third year (2024), he served as a key pillar of the team, helping his high school team to secure a top‑eight finish in the team competition at the Inter‑High School Championships. Individually, he reached the later rounds of several major national events, including the National High School Sumo Invitational Tournament in Umi and the Kanazawa High School Sumo Tournament, and represented Kochi Prefecture at the National Sports Festival (Kokutai), advancing into the final stages of the individual competition. At the Inter‑High School Sumo Championships, he reached the quarterfinals, finishing one win short of qualifying for sandanme tsukedashi.

Tatsubayama was recruited into Tokitsukaze stable by Tokitsukaze oyakata (former maegashira Tosayutaka) and, with special permission, he began training at the stable while still completing his high school studies, to help him transition into professional life. Although initially cleared to debut in May 2025, his professional start was delayed by an early setback: in January 2025, he underwent surgery to address a recurring dislocation of his right shoulder, postponing his entry into ozumō until the 2025 Nagoya basho.

He was given the shikona “Tatsubayama”, a name explicitly designed as a tribute to two of the sport’s greatest figures. The “Tatsu (dragon)” (龍) is taken from Asashōryū, his high‑school senior at Meitoku Gijuku, while “bayama” (葉山) comes from Futabayama, the legendary 35th yokozuna and founder of his  Tokitsukaze stable.

In his first official tournament in September 2025, he went 7–0 to claim the jonokuchi yūshō, displaying composure and physical dominance despite recently recovering from surgery. In the November 2025 tournament, he was 6-0 and ready to go into the final bout to force at least a playoff (if not take the championship outright) but was forced to withdraw after contracting cellulitis, which required eight days of hospitalization and resulted in a loss of roughly 10 kilograms.

Still only 20 years old, Tatsubayama profiles with a high ceiling. He is a technique‑reliable prospect whose amateur pedigree, physical readiness, and early professional results point toward an easy transition to makushita in the near term. The key question ahead is not whether he belongs above sandanme, but whether his deliberate, grip‑centric style can continue to hold up against heavier, more tactically disruptive opponents as the margin for error narrows.

Takahara (髙𠩤)

Stable: Futagoyama
Age: 19
Height (cm/feet-inches): 173 / 5’8”
Weight (kg/lbs): 116 / 254
Home prefecture: Kanagawa
High School: Asahigaoka High School
University: —
Career Record and notes: 22-6 (.786)
Debut: Nagoya 2025
Notes: —

So much optimism this time – as I think its likely!

Takahara is a Kanagawa‑born prospect whose profile blends long‑term competitive sumo training with explosive athleticism and an unusually strong mental drive. Takahara began practicing sumo in elementary school, starting in the 5th grade. Takahara attended Odawara Municipal Izumi Junior High School, where his development accelerated. He achieved an individual third place result in a regional tournament and helped his middle school team qualify for the national middle‑school championships, a first for his school. They finished in the top 32 nationally.

In parallel with sumo, Takahara pursued full‑contact karate at Sōtenjuku. His results were very impressive as he was a national runner‑up in 2020 and won a national championship in 2021. His dual‑sport background is widely credited with contributing to his explosive tachiai, body control, and speed. These are all traits that distinguish him from more orthodox amateur sumo prospects.

Takahara continued his sumo career at Shinmei Gakuen Asahigaoka High School, one of the stronger sumo programs (that of prospect Asahifuji). His high‑school achievements include winning the Kanagawa Prefectural Inter‑High qualifier in the open‑weight division and advancing to the top 32 nationally at the 2024 Inter‑High School Championships. As a sophomore, he won the Kantō Select Tournament and in 2024 he won the Kanagawa Prefecture individual open‑weight title. His sumo club coach provided good direction, technical instruction, and connections to the professional world. Takahara entered the “Mita connection”, a loose but influential pipeline of wrestlers developed under the guidance of the father of Mita (Futagoyama-beya). Mita’s father is a respected figure in amateur sumo training and one who has been influential in channeling his pupils to Futagoyama‑beya. Recruitment came directly and personally, as Futagoyama Oyakata visited Takahara’s school after being impressed. He joined Futagoyama stable immediately after high school despite suffering a significant setback: a shoulder surgery during his last year of high school.

Inside the stable, Takahara has quickly developed a reputation for intensity. He is frequently featured in Futagoyama‑beya’s YouTube channel, where he stands out for his go‑getter attitude, willingness to push himself during training, and visible competitiveness. Despite saying he is naturally shy, those around him note a clear “switch” that flips during training, marked by heightened focus, aggression, and decisiveness. He has also spoken openly about his admiration for senior stablemate Nabatame. His victories in mae-zumo against Tatsubayama (see above) and Nishimura (Ryūhō, see last entry) solidified him as a prospect among keen sumo watchers like Kintamayama – who automatically added him to the coveted “lover division celebs” list. His long‑term objective is explicit and ambitious: to reach sekitori status by the age of 20, a goal he has stated publicly and framed as a personal benchmark.

Takahara is a high‑energy, high‑intent prospect whose ceiling will depend on how effectively his athleticism can be integrated into the more punishing, tactically complex environment of Makushita. He represents one of Futagoyama stable’s most intriguing prospects.His shikona is currently his family name, but he uses kanji variants for both the Taka (like Takayasu) and the Hara characters.

Ōkaryū (大花竜)

Stable: Tatsunami
Age: 24
Height (cm/feet-inches): 178 / 5’9”
Weight (kg/lbs): 159 / 31349
Home prefecture: Aomori
High School: Sanbongi Agricultural High
University: Kinki University
Career Record and notes: 57-27-0 (.679)
Debut: Natsu 2024: Sandanme Tsukedashi
Notes: —

Possibility of reaching sekitori: 100%

I should miss a few of these entries more often. I was too busy with work to make the Kyushu 2024 update of this series and missed two “future” sekitori – both Toshinofuji (see last entry) and Ōkaryū. Maybe skipping these posts is good luck for new makushita aiming for the salaried ranks?

Ōkaryū’s rise to sekitori status has been built on elite amateur credentials, physical density, and a notably efficient transition from student sumo to the professional ranks. He comes from a deep sumo lineage. Like both his grandfather and father, he is an alumnus of the Sanbongi Agricultural High School Sumo Club, one of Aomori’s most productive amateur pipelines. He distinguished himself early at the national level: as a freshman, he placed third at the National Selection Hirosaki Tournament; as a sophomore, he reached the top eight at both the National Selection Towada Tournament and the National Sports Festival (Kokutai); and in his junior year, he placed third in the All‑Japan Weight‑Class Junior Heavyweight Division (100 kg+), and again reached the top eight at the Towada national selection event.

After graduating high school, Ōkaryū enrolled at Kinki University (Kindai). His breakthrough came in his third university year, when he captured the National Student Individual Weight‑Class Championship in the 135 kg+ division, defeating Ōnosato of Nippon Sport Science University (who was already amateur Yokozuna) in the final. This victory was Ōkaryū’s first national individual title and established him as one of the leading heavyweights in university sumo. As a senior, he served as vice‑captain of the Kindai team that  won the National Student Sumo Championship, ending a prolonged team title drought for the school. Individually, he advanced to the round of 16 at the National Sports Festival (Kokutai), a result that secured him sandanme tsukedashi eligibility. Over the course of his university career, he accumulated four major amateur titles. Through ties that included junior teammate Kiryūkō at Sanbongi High, he elected to join Tatsunami stable upon graduation.

On his professional debut as a Sandanme tsukedashi in May 2024, he took the shikona Ōkaryū (大花竜). The meaning of his shikona blends family symbolism with ambition. The character “花” (flower) was chosen deliberately, as it appears in the names of both of his sisters, while “竜” (dragon) reflects the aspiration to rise powerfully and continuously. At his first professional bout, the name was repeatedly misread aloud as “Daikaryū”. In his debut, he finished 6-1, with his only loss coming to Kyokukaiyū.

Technically, Ōkaryū is a fundamentals‑heavy yotsu specialist. His most frequent winning technique is yorikiri, though he is equally comfortable finishing with oshidashi or capitalizing on overextensions via hatakikomi. His sumo is built around absorption and control rather than speed, a style that has translated particularly well as the quality of opposition has risen.
