Kamitsuumi

Thanks. On the Japanese side though, it's always the Kitanofuji-Mainoumi combo doing days 1 and 15.

His father is the head sumo coach/principal at Tottori Johoku, one of the sumo powerhouse high schools. It's been speculated that Ishiura will be a sumo coach there, in order to secure a recruitment pipeline for Miyagino.

Did Hiro lose a bit of seniority at NHK doing this? Usually he does the day 1 commentary, but this basho he was on day 2.

Kaisei surely deserves a ceremony in the Kokugikan. But if Hakuho's danpatsushiki is "scheduled" to be October 1, 2023, I don't see how Kaisei is going to get his in a year.

According to the Japanese wiki he was the rikishi who led the Brazil delegation at Nagano 1998. You can hear the announcer say his shikona at the time (and his real name) Ikemori.

This is the query I checked: https://sumodb.sumogames.de/Query.aspx?show_form=0&rowcount=3&group_expand=on&group_by=basho&having=4&form1_rank=y2-y4, o2-o4, s2-s4, k2-k4 There doesn't seem to be any previous banzuke like this. Edit: my query misses cases where there is only 1 Yokozuna or 1 Ozeki, so I double checked these instances

It looks like a smallpox vaccine scar, which usually is on the left arm. Could this image be flipped?

The issue with the above is that you can't just multiple by 2 to get the answer: By inclusion-exclusion: {Probability of 9 consecutive heads or tails in 150} = {Probability of 9 consecutive heads in 150} + {Probability of 9 consecutive tails in 150} - {Probability of 9 consecutive heads and 9 consecutive tails in 150} Since the third term on the right hand size is non-zero, {Probability of 9 consecutive heads or tails in 150} < 2*{Probability of 9 consecutive heads in 150} Originally, in the nested for loop I had "range(1,10)" instead of "range(1,9)" (range is inclusive on the first parameter and exclusive on the second). This meant that I had an extra 1/512*P_{m-n} in each sum.

That's not exactly correct since each "try" (i.e. streak of one side winning, or RNG flips for 1/256) take up a different number of bouts (up to 9). By my calculation (by that I mean my python script) it's about 24.7% for 150 bouts. from collections import defaultdict p = defaultdict(int) p[9] = 1/256 for m in range(10,151): chance = 1/256 for n in range(1,9): chance += 0.5**(n) * p[m-n] p[m] = chance

In December 1971, the Kyokai was discussed in the National Diet for its various issues (connections to the yakuza, health issues, etc), and in response the Kyokai decided to ban middle schoolers from joining. Any middle schoolers who already joined could only participate on weekends in Tokyo (3 bouts per Tokyo basho) until they graduate.
