Kaisei is a Brazilian Japanese sumo wrestler. He made his makuuchi debut in 2011 so he’s been in the upper ranks for quite a while. His sanyaku debut will be in May. He will have a rough first week. He has never beaten a Yokozuna in 19 bouts. The only Ozeki he has beaten is Goeido, whom he’s beaten three times in five bouts. However, Kaisei’s only other Ozeki victory came against an injured Baruto in 2012. He will need to step it up if he hopes to stay among the upper ranks.
