I updated the Heya visualization. Along with a map of the stables, it’s got a table of various metrics. One key metric is the “Kachi Koshi Ratio” for the May tournament. The table at the bottom has the raw numbers. But in the visualization, we see that Makuuchi Powerhouse Oitekaze stable had a terrible tournament and lies near the bottom with a .25. Only two small stables, Kagamiyama and Kataonami had a lower ratio (0). The darkest purples come from another small stable, Nishikido. Among the bigger stables, Mitakeumi’s Dewanoumi (.6875) and Kasugano (Aoiyama/Tochinoshin) did better than .6667.
Inspired by Josh’s article about a hypothetical rikishi, hoping to select a stable, I added the “Student/Teacher” metric. As a parent, the student/teacher ratio of local school districts is always of interest when seeking a new house or when making the decision to look at private schools. With a sumo-context, Kasugano-beya has a powerhouse of 7 coaches available to help develop their 18 wrestlers, including recently retired Tochiozan (Kiyomigata-Oyakata).

You can sort the table by name (English alphabetical) or by any of the metrics. I’m eager to hear what you all think. If there are any new metrics you’d like to see or if you’d like to discuss any of the metrics found here, leave a comment. It was surprising to me to see how many stables are outside the Ryogoku area. I will be tracking the Kachi-Koshi ratio by stable for the Tokyo tournaments. I am interested to know whether increased commute times lead to lower performance. Araiso’s stable is scheduled to be considerably farther out in Ibaragi than even Shikihide stable. Sadogatake is the farthest “large stable” from Kokugikan in Chiba prefecture. Sakaigawa is next, over in Saitama near Oitekaze.
