Next tournament will have at least 3 former Makuuchi Yusho winners in Juryo (Tochinoshin, Ichinojo, Tokushoryu), possibly 4 if Asanoyama isn’t promoted… 

[Asashosakari 17,637]

I'd been meaning to post this ever since I worked out my juryo banzuke guess, and comparing it to the real thing reminded me just now: Hatsu 2023 is, by a mile, the new record holder in the number of juryo rikishi who fought to 10+ real losses.

That query is limited to the "small juryo" era since 1967 for a fair comparison, but even expanding it to the full 15-bout era, the most recent basho is still tied for the lead - with two tournaments that featured 41 and 45 (!) juryo rikishi, respectively.

And it would have been worse if Atamifuji's 3-8-4 had been added.  Also, with only 5 double-digit winners, the asymmetry is really striking -- no "diamond shape" to the final standings chart as often happens.

Occasions of new makuuchi, new juryo and new makushita do-beya rikishi in the same basho, during the 6 BPY era:

Dewanoumi 1964.01, Futagoyama 1981.01 , Isegahama 1965.05 and 1969.09 (promotions in all divisions), Kasugano 1976.11  , Kitanoumi 2012.01, Kokonoe 1978.07, Miyagino 1967.03 and 2023.03, Nishonoseki 1958.05, Tokitsukaze 1958.09

If I did the query correctly, Day 8 will be the first time in history with no Ozeki or Yokozuna on the torikumi. Seems really surprising, so someone please correct me if it's wrong.

Yes, but only for bashos where we have torikumi data. Japanese news sites state that this is the first time the torikumi has no Ozeki or Yokozuna starting from the Showa era.

For example there are bashos like Natsu 1904 where there were definitely days with no Ozeki or Yokozuna. However, since the actual torikumi data is not available, these bashos don't show up in your query.

I threw together some data today to see which active rikishi is the most capable technician. Its fun stats, but probably doesn't deserve its own thread, so I'll throw it in here.

My metric: Of all wins by all active rikishi, who has the greatest cumulative share of all of the winning techniques? That is, if you are the only one to have ever used a technique, you get 100% added to your total. If you've used a move 3 times and somebody else has used it only once, you'd get 75% added. Each yorikiri win is worth 0.001126%.

Here's the list of everyone with more than a 50% score, together with the moves they have more than 3% of:

Satonofuji, perhaps best known for the bow twirling he does at the end of each tournament day, is clearly sumo's supreme technician. I guess that makes sense, given that he was chosen to be one of NHK's technique demonstrators.

Four techniques have only been used by a single active rikishi:

• Ishiura's triple attack force out
• Fujinoteru's lifting throw
• Kotodairyu's inner thigh throw (which doesn't seem to have any video, it was back in 2009, before he started using his current shikona)
• Wakatakakage's rear lifting body slam from last year.

updating data with 1996-1999 matches

I was surprised to see Hidenoumi up there, then I remembered his rare technical prowess for pushing people out with his arse 

[Gurowake 3,730]

Erm, maybe you should remove the points for hansoku?

Hmm, the guys who have it in their list have actually got an unusual number of them. Midorifuji has three, Ishiura has two. There are only 55 in the dataset.

I didn't put any effort in to sanitizing the data. It's using results scraped from SumoDB (in an off-basho time of year to avoid beating the server too hard when it's busy).

Now that I think of it, my dataset probably sells Satonofuji's accomplishments a little bit short, as it only contains data starting from the January 2000 basho to the present (which is long enough to cover the whole careers of all the top division men), and he'd been fighting for several years at that point.

[Yamanashi 3,359]

I can't help but thinking that someone is going to tell Satonofuji about this, and then advise him that he could put the title out of reach if he could punch out a few amiuchi or maybe a sabaori.

[BlckKnght 22]

So, to give Satonofuji his full due, I scraped a couple more years of data, so that his matches from 1996-1999 are all included. His score goes up to the incridible 326%. None of the guys who started before him are anywhere near 50%, so I don't think I need to bring in more 90s data. I'm going to edit the post above to have the updated data.

I don't believe any of the other scores changed much, though there will be a  notable change after I add results from the current basho. Midorifuji's win on day 10 was by waridashi, which had been used by only twice before by currently active rikishi. The recalculation of its value will knock Hidenoumi well down the chart, and Sakura to less than 50%.

[Reonito 989]

Enho has run his career losses by oshitaoshi to 49, 4th all-time and trailing the leader, Kitaharima, by 15. His 47 such losses as a sekitori are far and away the most ever, 8 ahead of second-place Terao and Yoshikaze.

Dairaido is a combined 0-4 against the Sakamoto family, having lost twice to Tokitsuumi and once each to his sons.

Kitaharima is still actively getting shoved onto his bum and shows no signs of stopping. Enho will probably need more than those 15 losses!

True. Enho is a lot younger, so he has time on his side. Losing by this kimarite seems to be a hallmark of lightweight rikishi, for obvious reasons.

[Yamanashi 3,359]

Kitaharima is 36, with 1068 bouts, oshitaoshi 64 (12.1%) and, importantly, even if he hangs around a little longer it will probably be in Makushita where he only has 7 losses per basho to give ().

Enho is 28, with 436 bouts, oshitaoshi 49 (an amazing 23.3%) and seems to be a sekitori for now.

Although Kitaharima is eligible for a kabu, I haven't heard his name come up; he may retire soon anyway.

Statistics (as you know) are dicey things, but I guess we could estimate how long it might take Enho to pass Kitaharima for the "pancake championship".

Kitaharima: retires in 1 year = 6 basho = 42 bouts => (0.121)·(42) = 5+64 = 69 career oshitaoshi losses

Enho:69 - 49 = 20 to tie, 21 to go ahead; 21/0.233 = 90 bouts => 6.basho; so sometime in Natsu 2024.

[Note: Kitaharima is taller and heavier than Enho, and many of the oshitaoshi losses I've seen are the classic "big shove"; Enho comes in so low that his losses involve prying him up and flipping him over like an okonomiyaki (done very quickly by Tochinoshi on day 7)]

Juryo yusho winners Jan 2015 - March 2023 (N = 49):

Winning scores -- 10 (6), 11 (11), 12 (14), 13 (14), 14 (4), 15 (0)

Winner's rank -- J1-2 (13), J3-4 (9), J5-6 (8), J7-8 (3), J9-10 (2), J11-12 (9), J13-14 (4)

I tried to place the winners into one of three groups:

I (previous Makuuchi rikishi who are coming back after injury, demotion, etc.) 28

II (hot new prospects that are rising through Juryo, like Ms15TDs) 8

III Juryo regulars who (up to now) have spent most of their time in Juryo 12

[Note: I haven't placed Oshoma yet, as we don't know if he's a II or a III; I ranked Tsurugisho as a III, but he may make a home in Makuuchi in the future].

After 86 years of Futabayama winning a Yusho as shin-sekiwake, Wakatakakage won it last year as a shin-sekiwake, and now after exactly a year, Kiribayama wins it as shin-sekiwake.
