Chiyotasuke

I just now realized that Hoshoryu's result in his Komusubi debut is the same as his shisho , heya-mate Meisei and uncle's debuts (8-7). They all got their kachi-koshi on the final day too

All the shin- Komusubi, Sekiwake and Ozeki in Haru basho have gone kachi-koshi. Last time this happened was in Natsu 1976. Another similarity between these 2 basho to look at is the heya which the promotees belong to: Ozeki Asahikuni and komusubi Hoshoryu - Tatsunami Sekiwake Washuyama and ozeki Mitakeumi - Dewanoumi. And Atamifuji and Kurosegawa, who was also shin-juryo, are of Isegahama, and ended their basho at 7-8. (2 different Isegahama-beya)

Before Futabayama, Shimizugawa also had won the yusho in his Sekiwake debut. As a result of the Shunjuen Incident he couldn't make his debut at the rank in Haru 1932. So the query function didn't work here. I was informed about it when NHK showed this: (+) Wakatakakage is also the 3rd makuuchi champion from Fukushima pref. after Tokitsuyama and Tochiazuma I

Now it is certain that Wakatakakage will finish this basho as at least a runner-up, so I queried the SumoDB to find how many achieved it in their Sekiwake debuts. 12 rikishi did and only Futabayama had finished with a yusho. For 9 of them it was part of their successful Ozeki runs (*I'm not sure about Kagamisato, he did make Ozeki 3 basho later). So I'm excited about Wakatakakage's performance tomorrow and in Natsu basho

First I did this, then this. There seem to be quite a lot of rikishi. I only looked into the first few (Kotokanyu, Hakuryo, Kizenryu, Tochitenko have been ms10-ms1)

Last time a maegashira won his first 10 bouts was Homasho in Nagoya 2010. Takayasu is ranked higher than most of them as you can see here

Although he lost today, it's nice to see that Hoshoryu became one of 12 men who beat an ozeki in their first 4 meetings while being ranked at M-S (not Hakuho who had had 2 wins over Sekiwake Tochiazuma. Edit: And not Kotozakura either, as one of the win was fusen. So 12 men in total) • And with wins more than 4: Akinoshima (7-0) Konishiki, Toyonoshima (5-0) Chiyotaikai, Terunofuji (5-0) Asanoyama

Today in juryo division, Kaisho beat Kaisei after about a minute of good ai-yotsu stall. The reason I mention them is that they were heyamates for a short time in Tomozuna beya before Kaio branched out and took Kaisho with him. Must be a rare occurence that someone faces his former heyamate (Akinomaki predicted a Tomokaze x Yago match might happen too) Edit: And oh yeah, it must've happened more regularly in lower divisions, now that I think of it

Basho with new Ozeki, Sekiwake and Komusubi since 1900: Aki 2023 Haru 2022 Aki 2014 Hatsu 2002 Haru 1994 Nagoya 1987*, Hatsu 1983 Natsu 1976, Kyushu 1970, Aki 1970 Nagoya 1961, Aki 1960 Kyushu 1959, Natsu 1957, Hatsu 1953 Aki 1945, Aki 1944, Haru 1943* Haru 1937, Natsu 1932, Haru 1932, Natsu 1930 October 1927, Haru 1925, Natsu 1923*, Haru 1922 Natsu 1919, Haru 1915 Natsu 1909, Natsu 1905 * - with New Yokozuna too (In Haru 2022 and Haru 1922, Waka* Atsu* was promoted to Sekiwake )

Aand another one: Terutsuyoshi keeps his M11w rank for Haru after going 7-8 twice. This has happened twice in a row now

A small nitpick I'm sure I got right: Masudayama should be RS-Retired as sanyo, instead of RM again, which I figure is designated after turning 65. Here for example, Dewanohana & Kurosegawa are RS

Abbreviation for "Earlier/other retirement" of kabu is inconsistent. It seems it was initially RO (example), but now it's RE (with its explanation being just "RE", example)

The diagram also shows Kasugakuni's 3 shishos. Kasugayama: Kasugafuji - Hamanishiki - Nakagawa: Asahisato

Abi is the 4th man to get either jun-yusho or yusho on 2 consecutive basho at hiramaku rank. The 4 were 26-28 years old when they achieved it

Occurences of the same rank and side kept for 3 consecutive bashos while going MK in the first 2, since WWII: http://sumodb.sumogames.de/Query.aspx?show_form=0&columns=3&n_basho=3&shikona=Wakasugiyama,Kotoeko,Tobizaru&form1_rank=M&form1_wins=7&form2_rank=M&form2_wins=7 Tobizaru to be ranked at M8w in Hatsu 2022. *Edit: Also occured in juryo once: http://sumodb.sumogames.de/Query.aspx?show_form=0&columns=3&n_basho=3&shikona=Fukudayama&form1_year=196111

Reply to Tigerboy1966: In this thread, Nishinoshima said it was a yusho prize for a non-honbasho tournament. The pic of Yoshibayama is long gone and it's from 1956, but the description matches that from the 1954 pic above.
