Kaisei made his "san'yaku" debut in the May 2016 tournament, having been promoted to "komusubi" on the back of an 11–4 record from the rank of "maegashira" 7. He is the second wrestler from Tomozuna stable to reach "komusubi" since the present stablemaster took over in 1989 and the first since Kaiō in 1994. After coming through with an 8–7 record he earned immediate promotion to "sekiwake" for the following July tournament. In the last three tournaments of 2016 he posted losing records and dropped to "maegashira" 9 before recording an 8–7 in January 2017.
