I think this was an All Japan Championships semi-final match. It was widely speculated that Ono threw this fight to avoid a showdown with Hashimoto in the final and risk losing his spot to Hashimoto for the Rio Olympics. At 73kg Ebinuma was not in the running for that spot but Hashimoto and Ono definitely were. A few months later Ono defeated Hashimoto in a searing and controversial 21min contest to secure his spot on the Japan Olympic team. It was a controversial win because Ono kept stepping off the mat and did not get penalized. However Hashimoto was/is very skilled at pushing opponents off and making it look like they walked off. Ono and Ebinuma were very close friends and it is hard not to see how it was not a 'political' match.

He lost in his 2nd last competitive fight to igor wandtke makikomi at Olympic games

I remember watching that fight. It was the team event after Ono won the gold in the individual event. I was thinking as I was watching it that Ono would want to be careful because he looked like he was casually walking after Wandtke looking to score an exhibitionist style Ippon. He certainly got rid of that egotistical mentality in his last fight with the Frenchman. @@BearOZair2001
