Although there were previous reports about this in the Japanese press, they had ambiguous language, and were based on “associates”. Today, the report comes in directly from the NSK: “Former Sekiwake Yoshikaze (Real name Masatsugu Onishi) has retired, and taken on the toshiyori name Nakamura”.
His stablemaster, Oguruma oyakata, complimented Yoshikaze for doing straight-forward sumo.
Yoshikaze will now become Nakamura oyakata. The date of his danpatsu-shiki is not known at this time, but given the number of retirements lately, and that Aminishiki’s ceremony will take place on October 2020, there is a distinct possibility of this not happening before 2021.
