He made his professional debut in March 1983, and reached the top makuuchi division in January 1990, alongside his stablemate Oginohana, He achieved a winning record in his makuuchi debut which saw him promoted to his highest rank of maegashira 5. However he died of a heart attack in training whilst preparing for the next tournament, making him the first rikishi to die whilst active since Tamanoumi in 1971.[1] Following his death the Japan Sumo Association introduced mandatory ECG checks for all wrestlers and required installation of automated external defibrillators at every stable.[2] On 4 July 2019 his former stablemate Oginohana, now Dewanoumi Oyakata, collapsed at a training session whilst supervising jonokuchi wrestlers.
