The list gives a good impression of the size of the playerbase and a real sample of the relative rarity of Yakuman hands.
Currently the hundred wins span only seven hours, although that's probably peak time in Japan (17:00 to midnight).
The "big three" dominate but there are also a few more interesting cases.
32 x Four Concealed Triplets
29 x Thirteen Orphans
24 x Big Three Dragons
7 x Four Concealed Triplets with pair wait
3 x Little Four Winds
1 x All Honours
1 x All Honours + Big Three Drags
1 x Non-dealer instant win (Chiihou)
1 x All Terminals
1 x Nine Gates
For Yakuman frequencies on Tenhou within a much larger sample of all winning hands (645 million!) check this thread:

That sample is big enough to include Pure Nine Gates, Four Kongs and even nine hands with three Yakuman each.
