Heya Power Rankings: October 2017


Is it still October? OK, cool. A few folks have sent messages asking: “where in the heya are this month’s power rankings?” Here they are! Apologies for putting this together a little late, but as a measure of where everyone’s at, maybe it’s timely to publish this around the banzuke announcement. Of course, as stables don’t compete against one another, this is more of a fun exercise anyway.

I’ve made a couple changes this time from the original calculations. Owing to the craziness that was “Wacky Aki,” it didn’t really make sense to award a kyujo rikishi the same amount of points as one who battled all 15 days, only to fall to a 7-8 make-koshi. So, for the first time, I’ve introduced points deductions, only for kyujo rikishi:

  • 10 points deducted for makuuchi rikishi who is kyujo the entire basho
  • 5 points deducted for makuuchi rikishi who is kyujo for part of the basho
  • 1 point deducted for juryo rikshi who is kyujo for any or all of the basho
  • 0 points deducted for rikishi in either division who is kyujo but still manages a kachi-koshi (this did not happen at Aki, but it’s a good rule to set going forward as fighting through an injury to achieve a winning record should still be recognised with the full amount of points)

Finally, Andy had asked a cool question after a previous iteration of these rankings: what if we could also measure by ichimon – the network of stables to which each heya is affiliated? I’ve now included a chart of that as well – it could be interesting to watch over time. Changes in the strength of a stable can take years to materialise in many cases, so I would imagine it will take several years to see shifts in the strength of groups of them.

chart-8

I’ve added in Naruto-beya here (formed in April this year by former Ozeki Kotoōshū), which isn’t of consequence yet but perhaps someday soon it will be. Let’s jump into the “Billboard” style Top 20 chart form (ties broken by previous ranking with the most recently better heya ranked higher):

  1. (+1) Isegahama. 147 points (+52)
  2. (+4) Sakaigawa. 67 points (+20)
  3. (+4) Kokonoe. 56 points (+13)
  4. (+-) Tagonoura. 55 points (-20)
  5. (+5) Oguruma. 48 points (+16)
  6. (-5) Miyagino. 40 points (-67)
  7. (+8) Takanohana. 38 points (+20)
  8. (-3) Oitekaze. 36 points (-12)
  9. (-6) Kasugano. 30 points (-48)
  10. (-2) Izutsu. 30 points (-10)
  11. (-2) Dewanoumi. 25 points (-10)
  12. (+7) Onomatsu. 25 points (+12)
  13. (-1) Sadogatake. 24 points (+2)
  14. (**) Shikoroyama. 23 points (+17)
  15. (+1) Hakkaku. 20 points (+2)
  16. (**) Takasago. 20 points (+15)
  17. (-6) Kise. 15 points (-10)
  18. (**) Tomozuna. 17 points (+5)
  19. (-5) Kataonami. 15 points (-5)
  20. (-3) Tokitsukaze. 15 points (even)

Movers

As opposed to August’s chart which was fairly placid, the combination of a bizarre basho along with some new rules has created all manner of changes and lots of movers.

Isegahama returns to the top spot, because when you have a champion Yokozuna, everything is wonderful. Harumafuji’s title more than makes up for Terunofuji’s injury-inspired absence, but while that’s the main driver, the stable’s four other sekitori all scored more points than in the last basho as well. Sakaigawa vaults up to #2 fuelled by a Goeido jun-yusho, in spite of Sadanoumi’s kyujo start.

Kokonoe makes up the final spot in the top 3, owing to a solid basho in which all of their six rikishi matched or improved their standing from the previous rankings. Oguruma places in the top 5 owing to the continued resurgence and special prize of Yoshikaze along with a debut point for Yago, while Takanohana-beya benefits from continued good performance from the potential starting to emerge in Takakeisho and a rebound from Takanoiwa.

Losers

Three stables took a particularly significant tumble this time, all owing to missing stars:

Miyagino lost a truckload of points owing to its yusho-holding Yokozuna missing the entire party, while Ishiura continued to struggle. Reinforcements may soon be on the way as we have covered in some detail, but a present Hakuho is a dangerous Hakuho and this may be a one-basho blip for their chart position, while Ishiura may well benefit from diminished competition and be able to challenge for a Juryo yusho like many before him who have made the drop.

Tagonoura’s drop is simply down to the absence of its only sekitori for all (Kisenosato) and most (Takayasu) of the tournament. It is more difficult to forecast a rebound here, not knowing if either will really be able to withstand the full tournament in Fukuoka. And finally, Kasugano takes a huge drop, owing to its Nagoya jun-yusho winning slap-happy Bulgarian missing half the tournament. Tochinoshin’s make-koshi didn’t help matters.

Up Next

Chiganoura-beya will post points next time for the first time, as Takanosho (formerly Masunosho) makes his Juryo debut. He’s only their second ever sekitori since reforming 13 years ago. And Takagenji’s return to Juryo may help Takanohana move further yet up the ranks should their other rikishi be able to maintain their recent encouraging performance.

Finally, while a number of other heya have numerous immediate promotion candidates, the longer term outlook for Miyagino-beya is starting to get interesting. While the focus is on Ishiura putting it together and Hakuho staying healthy, Enho and Hokaho could put themselves into promotion contention early in 2018. We’ve talked breathlessly about the former, but the latter has quietly racked up 5 straight kachi-koshi. While his track record and somewhat advanced age makes it unlikely he would ever make a serious or sustained dent in the second tier, the presence of 5 rikishi headlined by a constant yusho-challenger could give Miyagino depth similar to their ichimon-mates at Isegahama.

Speaking of which… here are those ichimon totals:

chart-9

While I’m comparing these to the previous basho, I may start to show a longer term view when we revisit the rankings in December.

Heya Power Rankings: August 2017


Welcome to the third installment of the Heya Power Rankings. The purpose of this series is to gauge how the various stables are performing relative to each other, and track their progress over time. Now that we’ve been looking at this over the first four basho of 2017, we can start to identify some trends.

For a refresher on the methodology and calculations behind these rankings, visit the original post. Let’s jump in:

chart-7

And in “Billboard” style Top 20 chart form (ties broken by previous ranking with the most recently better heya ranked higher):

  1. (+1) Miyagino. 107 points (even)
  2. (-1) Isegahama. 95 points (-29)
  3. (+1) Kasugano. 78 points (+20)
  4. (-1) Tagonoura. 75 points (even)
  5. (+4) Oitekaze. 48 points (+14)
  6. (-1) Sakaigawa. 47 points (-3)
  7. (+-) Kokonoe. 43 points (+2)
  8. (+-) Izutsu. 40 points (even)
  9. (+3) Dewanoumi. 35 points (+5)
  10. (-4) Oguruma. 32 points (-10)
  11. (-1) Kise. 25 points (-8)
  12. (+1) Sadogatake. 22 points (-7)
  13. (-2) Isenoumi. 20 points (-13)
  14. (+-) Kataonami. 20 points (-5)
  15. (+-) Takanohana. 18 points (-6)
  16. (+-) Hakkaku. 18 points (-5)
  17. (+-) Tokitsukaze. 15 points (-5)
  18. (+1) Takadagawa. 15 points (-2)
  19. (-1) Onomatsu. 13 points (-7)
  20. (**) Nishonoseki. 13 points (+5)

Movers

Well, there aren’t really that many, which may come as a surprise, but less points were awarded on the whole due to there only having been 2 special prizes this time, and a clear jun-yusho (Aoiyama). We can probably isolate 5 clear “winners” this time out:

Miyagino takes the top spot on the same points total as last time, so this is more a product of Isegahama not getting the production despite having twice as many rikishi. The only change here is that Yamaguchi and Ishiura trade make- and kachi-koshi, as of course Hakuho wins another yusho.

Kasugano makes another big points gain off the back of Aoiyama’s pushy-thrusty jun-yusho, but this isn’t as spectacular a gain as it would have been for another stable as it replaces Tochinoshin’s jun-yusho last time out. That being said, all three rikishi here performed well and even if they lose points for not mounting a championship push next time out, we should see some promotions and hopefully their inevitable fall down the power rankings won’t be so tough.

Oitekaze makes a big move up the charts off the back of Daiamami’s Juryo yusho. The fun might stop there. The stable is otherwise looking at a series of demotions (including the worrying health of top man and “Mr. Popularity” Endo) in spite of this, and will lose Tobizaru to Makushita in September.

Dewanoumi has moved up to the limit of what they can achieve without special prizes, yusho challenges or Ozeki promotions from Mitakeumi. Worryingly for a stable of 16 rikishi, only 2 of the men behind Mitakeumi have put up back to back kachi-koshi (and one of them is 33 year old Kihonoumi), so it’s going to be up to him for the foreseeable future. Finally, Shohozan propels Nishonoseki onto the listing in the final position, off the back of a nice tournament.

Losers

Andy referenced that he wanted to see what would happen to Sadogatake on this chart and the results are surprising – they actually move up a spot, but again this is just due to less points having been awarded in total, as the stable has lost 8, 6 and 7 of our points in each of the past three tournaments. Mostly this is of course due to Kotoshogiku fighting at lower levels and not winning, but this slide is going to continue as we’ll see demotions for all 3 sekitori. Kotodaigo will fight at his highest level in Makushita at Aki, but unless he has a big tournament then we won’t see him at Juryo until the new year, at which point the situation could be considerably more dire and there aren’t many more reinforcements coming any time soon.

Isegahama‘s drop is largely down to Terunofuji’s downturn in performance and Harumafuji’s failure to challenge for the yusho, but a decent tournament from either (however unlikely) could see them regain the top spot next time out. Kise takes a bit of a hit owing to Ura’s injury-influenced make-koshi, but will have a decent spot at at least holding their position next time out due to a pair of Juryo promotees in Kizenryu and Daisedo. The rest is much of a muchness, but a word for Isenoumi who will be reliant on Ikioi regaining his form to move back up the listings.

Up Next

We noted last time that Kise had reinforcements on the way, and had a remarkable 11 rikishi fighting at Ms19 or higher in Nagoya. Two have been promoted, but 24 year old university man Kizaki may not be far behind. We highlighted his performance last time out, as he’s never suffered a make-koshi in his 8 competitive tournaments so far (including zensho-yusho at Jonidan and Sandanme). He’s taken a minute to acclimate to Makushita but might be on the cusp at Aki, after another solid 5 win performance in Nagoya at Ms7. Shimanoumi’s Juryo comeback bid was halted in Nagoya, but having put up 3 wins he should get another bite at it this time.

Arashio-beya has been feasting and more recently in famine depending on Sokokurai’s results, but Wakatakakage has been rocketing up the banzuke and could be around to provide backup soon. He’ll be due a big promotion to the top end of Makushita after a 6-1 tournament. Likewise, Takasago‘s Murata may be arriving soon to provide backup for Asanoyama having lost the Natsu yusho duel to Wakatakakage back in Sandanme, and having adapted almost as well to the next level of competition.

Heya Power Rankings: June 2017


With the banzuke announcement just a few days away, it’s time to revisit the Heya Power Rankings series. Thanks to everyone who commented on the first version of this post – this time I’ve been able to make the key update of stacking the bars vertically, and hopefully by the time August rolls around I can get them sorted properly and then we’ll really be off and running!

For a refresher on the methodology and calculations behind these rankings, visit the original post. I’m pretty happy with how this held up for the second version – for example the accomplishments of Tochinoshin (kachi-koshi and jun-yusho from M12) are ranked equivalent to Tamawashi’s kachi-koshi at S1, and that seems fair. Without further ado:

chart-2

And in “Billboard” style Top 20 chart form (ties broken by previous ranking with the most recently better heya ranked higher):

  1. (+1) Isegahama. 124 points (-1)
  2. (+2) Miyagino. 107 points (+57)
  3. (-2) Tagonoura. 75 points (-55)
  4. (+5) Kasugano. 58 points (+24)
  5. (-2) Sakaigawa. 50 points (-10)
  6. (+5) Oguruma. 42 points (+15)
  7. (-1) Kokonoe. 41 points (-2)
  8. (-3) Izutsu. 40 points (-5)
  9. (-2) Oitekaze. 34 points (-4)
  10. (+3) Kise. 33 points (+9)
  11. (+7) Isenoumi. 33 points (+18)
  12. (+3) Dewanoumi. 30 points (+10)
  13. (-5) Sadogatake. 29 points (-6)
  14. (-2) Kataonami. 25 points (even)
  15. (-5) Takanohana. 24 points (-6)
  16. (-2) Hakkaku. 23 points (even)
  17. (-1) Tokitsukaze. 20 points (even)
  18. (**) Onomatsu. 20 points (+15)
  19. (**) Takadagawa. 17 points (+8)
  20. (**) Minato.  / (-3) Tomozuna. (both 13 points)

Movers

Isegahama takes the top spot this month on a slightly diminished score owing to quality AND quantity: Terunofuji’s second straight jun-yusho and consistent levels of performance across the board push them up to the summit. Miyagino vaults up as the greatest gainer on points owing mostly to Hakuho’s zensho-yusho (we’re not currently giving a bonus score for a 15-0, but this is something to think about), and Ishiura grabbing a KK didn’t hurt.

Kasugano takes a big jump up the listing owing to a big performance from Tochinoshin which more than offset declines elsewhere. Yoshikaze’s special prize gives Oguruma a boost, while all four Kise rikishi grabbed winning records to propel the stable forward with modest gains. Isenoumi is the greatest chart gainer with just two rikishi, but Nishikigi’s Juryo yusho and Ikioi’s regained form give the heya a big boost. Dewanoumi’s sole contributor Mitakeumi grabbed a special prize and he’ll likely have a good shot to maintain his score next time out as he will in all likelihood fight at a higher level.

Finally, 3 new heya hit the chart as Onosho’s performance drives Onomatsu, Kagayaki and Ryuden’s solid performances put Takadagawa on the board, and Ichinojo grabs a kachi-koshi for Minato.

Losers

Tagonoura lose their grip on the top, but this is simply owing to Kisenosato not winning (in any capacity). Their top 3 spot should be relatively safe however, with Takayasu’s promotion confirmed, and both of them when on-form now represent title challengers. Elsewhere, Sakaigawa takes a hit just owing to Toyohibiki coming off a Juryo yusho onto a make-koshi and not much support among the rest of the crew beyond Goeido. Meanwhile, Kokonoe’s quality doesn’t translate to quality as despite 6 sekitori, only 3 could manage winning records and the toppermost – Chiyonokuni and Chiyoshoma – ran into a san’yaku slaughterhouse.

Up Next

Takanohana could be set for another dip, with Takagenji heading out of Juryo and Takanoiwa and Takakeisho likely swapping ends of the banzuke. Tomozuna’s fortunes will also likely get worse before they get better, with Asahisho likely following Takagenji, moviestar Kyokutaisei set for a drop down to the nether regions of Juryo, and Kaisei looking like he may only be a couple tournaments behind.

Shikoroyama (not ranked) should grab their second Juryo rikishi as Abi should certainly be promoted (5-2 at Ms1), and one would think Iwasaki (6-1 at Ms2) would join him in the pro ranks to give Oitekaze a shot in the arm. If Daishoho can get his act together soon and join up later this year, the stable would have a truly impressive number of rikishi in the top 2 divisions.

Kise had a great basho at Natsu as outlined above and they may also be ready to call on reinforcements soon: they boasted 7 rikishi between Makushita 1 and Makushita 12 and while none look like certain promotion candidates for Nagoya… ALL of them scored winning records, as did 2 of the 3 just behind (so that’s 13 of their top 14 with a kachi-koshi – bear in mind some stables don’t even have that many rikishi in total!). As always with the larger stables, a number of these guys are journeymen and also-rans, but the names to watch here are Shimanoumi (5-2 at Ms5W won’t get the job done this time, but he’s scored no less than 5 lower division unbeaten yusho and will be determined to get back to Juryo after fighting back from a period out of competition), and former university man Kizaki (who has raced to the top of Makushita in a year with 7 straight KK, including a pair of yusho).

Introducing the Heya Power Rankings


takayasu-training
Where winning is born

Now that Haru is in the books, I thought it might be fun to dig back into the maths and introduce an equation to work out which of the Heya, or sumo stables, are the real power players at the top end of the game. If it looks like we’re on to something, then perhaps it’s something we can revisit after future tournaments as well. As this is our first post on the subject, let’s tackle the methodology and then we can get into the rankings for Haru and analysis. So, whose chanko nabe tastes the best?

Methodology

In order to work this out, I built a points system which can be loosely based around these Three R’s: Ranking, Results, Rewards. Very simply put, a heya should get points for the level at which their rikishi perform, the results they achieve, and the rewards which bring them glory. All good positive stuff.

Ranking

Points are awarded for fighting at the following ranks:

  • Yokozuna: 40
  • Ozeki: 30
  • Sekiwake: 20
  • Komusubi: 15
  • Maegashira 1-5: 10
  • Maegashira 6-10: 8
  • Maegashira 11+: 5
  • Juryo 1-7: 2
  • Juryo 8+: 1

I separated Maegashira and Juryo into separate points categories as rikishi at the various ends of these ranks tend to have vastly different schedules. Fighting at a Maegashira 2 rank and having to face the likes of Hakuho is a bigger accomplishment than fighting at Maegashira 14. And being Hakuho is an even bigger accomplishment. So the points should be awarded accordingly. This obviously could be scaled up to accommodate even lower ranks, but it makes sense to start awarding points based on the world of professional sumo.

Results

I added 5 points for scoring a kachi-koshi in makuuchi, and 3 points for achieving a kachi-koshi in Juryo. I did not subtract points for scoring a make-koshi. Again, the rationale here is that fighting at a particular rank is the achievement. Achieving success at that rank should be recognised. Achieving failure at that rank will be reflected by the lower rank the rikishi will receive in the next banzuke, and therefore the lower score that the heya will receive in these next rankings. So, theoretically, it takes care of itself.

Additionally, if you follow the above logic, it stands to reason that a rikishi competing at the top end of Juryo and achieving kachi-koshi and on the cusp of promotion (2+3 points) is fighting at a similar level to a rikishi at the bottom end of Maegashira rank who gets a make-koshi and is in danger of demotion (5+0).

Rewards

Here’s where we will create variance from month to month, with points being awarded for the following achievements:

  • Yusho (Makuuchi): 50
  • Jun-Yusho (Makuuchi): 25
  • Makuuchi Special Prizes: 10
  • Yusho (Juryo): 15

At the end of the day it’s really all about winning the big prizes, and these represent prestige. These are the people who have been the focal point of the two weeks that have passed, either because they have outperformed their level, they have challenged for the yusho, actually won it, won a big promotion up to the next level, or all of the above.

Haru-basho Power Rankings & Analysis

PowerRankings

What we’ve got above is a bar chart of January’s ranks vs. March, so that we can see for this first edition which stable is at the summit of the sport, who’s improved their standing, and also how the Haru basho might have negatively impacted stables. Here’s our inaugural top 20 chart, with their score in brackets:

  1. Tagonoura (130)
  2. Isegahama (125)
  3. Sakaigawa (60)
  4. Miyagino (50)
  5. Izutsu (45)
  6. Kokonoe (43)
  7. Oitekaze (38)
  8. Sadogatake (35)
  9. Kasugano (34)
  10. Takanohana (30)
  11. Oguruma (27)
  12. Kataonami (25)
  13. Kise (24)
  14. Hakkaku (23)
  15. Dewanoumi (20)
  16. Tokitsukaze (20)
  17. Tomozuna (19)
  18. Isenoumi (15)
  19. Arashio/Minezaki/Nishonoseki (10)

The headliner for the second consecutive basho is the Tagonoura-beya, headlined by Shin-Yokozuna Kisenosato‘s heroic yusho, and another prize-winning outing by san’yaku fixture Takayasu. Perhaps unsurprisingly, the dominant Isegahama is not far behind, off the back of several prominent rikishi towards the top end of the banzuke and a just-nearly performance by Terunofuji. We can probably expect to see these two stables in or near the top two for some time to come, especially if Takayasu is successful in his Ozeki run.

Taking the bronze medal this time, it’s Sakaigawa: a stable with a number of makuuchi wrestlers and featuring the Juryo yusho winner Toyohibiki, who we’ll see back in the top flight for Natsu. While it’s not impossible, Sakaigawa will have a challenge to hold onto a position in the top 3 in May. Goeido will need to chase a kachi-koshi to retain his Ozeki status, but they may lose 2 rikishi from makuuchi to Juryo with demotions, and the next best heya Miyagino will hope for a healthier outing from Hakuho and better returns from Ishiura as he tries to cement his place in makuuchi.

Looking at whose stock plummeted the most this month, you can’t look further than the first name on the list. With only one rikishi in the top 2 divisions, Arashio‘s prestige is wholly dependent at the moment on the performances of Sokokurai, whose gino-sho winning Hatsu was followed up with an 11 loss outing this time around. Solid but unspectacularly performing heya with a diversity of competitors (e.g. Kokonoe) are better able to insulate themselves from this kind of performance, and Arashio doesn’t have anyone else near the top divisions at the moment.

On the whole, this exercise has shown that out of all of the places that rikishi live and train, about a dozen are real players at the top end of the game, and another dozen are developing middling talent trying to gain a foothold in the professional ranks. The rest are in limbo, either unable to produce top level talent at the moment or simply in a transitional period where their top level participants have recently retired or been demoted while they try and bring through a new generation of rikishi with the ability to compete at the highest level.

Looking ahead to Natsu, I don’t think we should expect much change in the top 5. A few stables under the radar who might make moves one way or the other in the near future:

  • OitekazeEndo will move up, and may face a tougher schedule given that many of the rikishi in front of him this time out are staring at demotion. Meanwhile, Daieisho‘s due a promotion and Oitekaze’s quintet could be joined soon in the professional ranks by Iwasaki, who picked up a kachi-koshi at Makushita 3, and Daishoho, who made his brief Juryo debut in November and just put up 5 wins at Makushita 7.
  • Takanohana: As Andy noted earlier in the week, Takagenji is set for his Juryo debut at Natsu, and while Takanohana isn’t teeming with the sheer volume of rikishi that you might see at other stables, there are actually a couple more young wrestlers not far behind. Star man Takanoiwa‘s results have been volatile, but he has made a step forward in the past year which is that he’s now more able to cope with what the schedule throws at him at the lower end of makuuchi. Likewise, Takakeisho seems to be settling in well as a rank-and-filer and will move up the banzuke next time out.
  • Sadogatake: It’s tough to call a heya with such a rich history at the top level “under the radar,” but they’ll take a hit if Kotoshogiku does retire or show diminished performance following a soul-crushing nearly-basho in March, and it would be charitable to say that Kotoyuki hasn’t been at his best recently. He looked overpowered and out of sorts more often than not at Haru. Realistically the next wave of talent here is at least a couple of years away – there are a handful of journeyman rikishi at Makushita level already, but the next youngster showing serious promise looks to be 19 year old Kotokamatani who just finished up a 5 win basho at Sandanme 3 and is primed for already his second spell at Makushita having only made his tournament debut last January.
