Currently I’m facing injures again which was anguish of entire my sumo life. That purpose is helping people have injures such as me by my instructs. Therefore my way to be a sports instructor was began at FLEX Tsudanuma.

My sumo life was always face injures in a word. I’ve participated in sumo world when 18 years old with dreams. Me took around 9 years to promoted for Sekitori “Juryo” of higher position. Ironically, at same year I was demoted to lowest position because of both knees injured. After 2 years, I’ve reached "Higashimaegashira 5 maime", highest position on my career.

It was a life of sumo wrestling with injuries, but it taught me that if you don't give up, you can seize infinite possibilities. I would like to let as many people as possible know the culture of sumo, which taught me how to live.

 Let’s join us and discover sumo world! Dosukoi!
