Trivia bits

[Gurowake 4,123]

From as best as I can tell doing research starting from the Wikipedia list of Makuuchi speedruns from Maezumo, the previous record for rise to san'yaku from Maezumo was 14 basho, held by Kotooshu, Konishiki, and Asashoryu.  Aonishiki is (presumably) going to get there in 11.

[Jakusotsu 6,187]

This was the first basho since 1978.07 with every Makuuchi rikishi getting at least four wins.

If it wasn't for Wakanosho's kyujo, it might have even gone back to 1975.11 including Juryo. These three were the only such basho in the post-war era.

Why do head to head matchups of Juryo .vs. Makushita rikishi tend to strongly favor the Makushita rikishi?

Juryo vs Makushita since year 2000: 803-935

I don't know if I would call 46.2% vs 53.8% strongly favoured. In any case, it's largely carried by actual exchange bouts on the final three days, which almost entirely feature makushita rikishi who have done well versus juryo rikishi who have not done well. From Day 1 to 12 the head-to-heads are 524-579 (47.8% - 52.2%), on Days 13 to 15 they're 279-356 (43.9% - 56.1%).

Edit: Also, the makushita advantage in the Day 1-12 bouts has outright evaporated in recent years.

I think that can be taken as potential evidence that their recent strictness in exchanging rikishi between makushita and juryo may have some justification to it, in that it is putting fewer makushita-strength rikishi into juryo spots through sheer luck and fewer juryo-strength rikishi into makushita.

(And a less charitable explanation especially for the pre-2011 numbers would be that there may have been sizable amounts of juryo rikishi who held their ranks through yaocho, and their relative lack of ability was exposed when fighting makushita opponents who had no reason to throw the bouts.)

Makushita rikishi still lead the Day 13-15 totals for the years 2019-2025:

Breaking it down by day. Interesting pattern. Not sure it's just a day 1-12 vs 13-15 divide. That is interesting with the recent change. I noticed that in Makuuchi vs Juryo bouts also, with Makuuchi faring better starting ~ the same time.

Another thing that may be having an impact - but which will be tough to conclusively isolate because the individual numbers of matchups are getting very small at that level of granularity - is an increased focus on making the pairings "by formula" from Day 1 to 12. The last basho was a good example of that:

Basho	Day	Rikishi 1				Kimarite		Rikishi 2
		Rank	Shikona	Result				Rank	Shikona	Result
2025.05	1	Ms1e	Kitanowaka	0-1 (3-4)		oshidashi		J14w	Mudoho	1-0 (5-10)
2025.05	2	Ms1w	Akua	1-1 (2-5)		hikiotoshi		J14e	Mita	2-0 (8-5-2)
2025.05	3	Ms2e	Oshoryu	0-2 (2-5)		yorikiri		J13w	Daiamami	1-2 (7-8)
2025.05	6	Ms2w	Dewanoryu	1-3 (3-4)		yorikiri		J13e	Miyanokaze	2-4 (6-9)
2025.05	7	Ms3e	Otsuji	4-0 (7-0)		oshidashi		J12w	Nabatame	5-2 (8-7)
2025.05	8	Ms4e	Ishizaki	3-2 (4-3)		kotenage		J12e	Mitoryu	4-4 (8-7)
2025.05	9	Ms4w	Kotokuzan	3-2 (5-2)		okuridashi		J11e	Kazekeno	6-3 (9-6)
2025.05	10	Ms5e	Kyokukaiyu	4-2 (5-2)		yorikiri		J14w	Mudoho	5-5 (5-10)
2025.05	11	Ms1e	Kitanowaka	3-3 (3-4)		hikiotoshi		J14e	Mita	7-4 (8-5-2)
2025.05	12	Ms2w	Dewanoryu	3-4		yorikiri		J13w	Daiamami	6-6 (7-8)

The only skips were Ms3w on Day 8 (Hokutofuji kyujo/intai), Ms5w on Day 11 (Tochimusashi already MK at 1-4), and then Ms1w and Ms2e on Day 12 (Akua and Oshoryu also already MK), and on the juryo side J11w on Day 9 (Wakanosho kyujo by then). Other than that, strict pairings in order down to Ms5 and up to J11, and then just starting over again. That's a pretty common sight these days. (Although the Day 12 pairing may well have been just a coincidence as that was also a proper exchange-style matchup between Dewanoryu and Daiamami.)

Before the last few years, they seemed to be using more discretion in selecting the rikishi on both sides, and some anecdotal evidence would be that the only cases of 0-3 Ms rikishi appearing in juryo on Day 7 were relatively recently, as were the only cases of 7-3 juryo rikishi being selected on Day 11. (And the 6-4's only go back to 2016, too.) Basically, the past approach was more geared towards treating all the pairings as "exchange bouts" between underperforming juryo rikishi and at least average performing makushita guys. Right now, the only exclusion rules being respected seem to be that the Ms rikishi can't be MK yet and the juryo rikishi not KK. That should be leading to matchups that are more favourable to the juryo side on average.

In 2009, Hakuho went 14-1 four times, only one of which was a yusho! He finished his career with four 14-1 basho in which he did not take the title, something that's only happened a total of 33 times in the six-basho era.

[Reonito 1,613]

We've had 32 basho since the start of 2020. 93 rikishi have appeared on the Makuuchi banzuke during this time, but only six have been there for all 32. Any guesses before you click?

With an initial short list of 7, I got 5. I considered Meisei but then I remembered that big juryo playoff that featured him and two other Tatsunami guys, which seemed too recent an event. That still left one mistake, namely Tobizaru instead of Kirishima...mistaken assumptions about which guy had come up when, I just remembered correctly that neither had been demoted since then.

[Reonito 1,613]

Two of the six drop out if you expand the window to 2019-now, the remaining quartet is still there in 2018, one drops off in 2017, the trio is all there in 2016 (that's 56 consecutive basho!) and then we're down to the top two, one of whom has been in the top division for 71 consecutive basho, the other for a whopping 83 since debut.

Am I the only one seeing that all the hyperlinks in this post are cencored with black bars? Is it due to the blacklisting thing?

I think it's to give people an opportunity to guess themselves.

[Wakawakawaka 186]

Fun experiment I thought I'd try; call it the 'rare kimarite index'. Take each rikishi's wins, divide it by how often the kimarite occurs, do that for each kimarite, then average it out.

For example, if a rikishi won all 100 of their matches by Yorikiri, and in all of Ozumo yorikiri accounts for 25% of wins: 100 (number of yorikiri wins) / 0.25 (average occurance of yorikiri) / 100 (total number of rikishi's wins): RKI = 4.

The results for the most part I think align with intuition.

Curious to see some names far up (e.g. Shonannoumi, Takayasu) and some far down (e.g. Tokihayate). It also implies that Aonishiki is more "skilled" than fellow rookie Onokatsu.

Yeah Shonannoumi was probably the biggest surprise near the top. Takayasu is a crafty vet that can do a bit of everything, so I'm not shocked by that. Onokatsu has a whopping 67.9% of his wins by yorikiri, that's why he's down there.

Also just for fun: The nephew leads the uncle by a whopping 2 points lol.

Any rikishi in lower divisions or the past that come to mind for curiosity? I wonder who has the highest of all? Can anyone beat Ura?

EDIT: Nvm, the other Tzutaezori king Asakiryu down in Sandanme: RKI = 835.

Kyokushuzan had been dubbed "the department store of kimarite", and Mainoumi might score high as well.

Edit: Akua's knack for kakenage could also be contributing.

Wow. Looks like we have a winner.

[Wakawakawaka 186]

Couple random things while I was digging that caught my eye.

Sadanoyama: Natsu 1961 - Lost to a Juryo rikishi, but won the Makuuchi yusho.

Takatoriki: Haru 2000 - Faced a Juryo rikishi and 2 Yokozuna in the same basho.

EDIT: Another random tidbit

The last time a Yokozuna entered a basho in which he faced a Maegashira, and did not give up a kinboshi, was Kyushu 2021, when Terunofuji got his zensho.
