Sumo stablemaster Takanohana was discharged from hospital on Wednesday, one day after he was admitted following a fit of convulsions.

The 46-year-old former grand champion told Kyodo News at Akita Station that he was "just discharged" from hospital, without elaborating.

The Japan Sumo Association had said he would be hospitalized for examinations after he fell unconscious during a training session in the city of Akita.

An emergency call was made at about 10:10 a.m. Tuesday after Takanohana had a fit while coaching wrestlers during a regional sumo tour in the city. He recovered consciousness before an ambulance arrived and was able to speak at the hospital, according to association officials.

The celebrated former yokozuna, who won 22 tournaments in the top division, has been in the spotlight in recent months due to long-standing friction with the JSA.

In January, he was dismissed from his position as a JSA board director over his failure to promptly report to the sumo governing body that a wrestler from his stable had been beaten and injured by yokozuna Harumafuji, a scandal that led to the retirement of the grand champion.

Takanohana attempted to regain his spot on the board of directors by running in an election in February, but failed as he received just two votes in the ballot of all 101 sumo elders.

In March, he was demoted two ranks within the JSA's hierarchy, to the lowest of seven ranks, due to his absence without permission from the Spring Grand Sumo Tournament and lack of supervision of a wrestler from his stable who assaulted a junior wrestler.
