Osawa is a successful wrestler. Amongst his successes was his participation in the 8th World University Wrestling Championship in Greece where he won gold in the 60 kg division. He also won the All-Japan Freestyle Wrestling Championship 60 kg division in 2007, which gave him his entry into Sengoku.

Sengoku

In May 2009, Osawa made his Sengoku debut at Sengoku 8 against Kota Ishibashi. Osawa won the bout via unanimous decision (20–18, 20–19, 20–19).

Three months later, Osawa returned at Sengoku 9 against Toru Harai. Late in the first round, Osawa defeated Harai via TKO (punches).

 at Sengoku 11. Mann dominated the fight and claimed a unanimous decision victory, handing Osawa his first professional loss.

At Sengoku 12, Osawa returned to face Kyung Ho Kang. In another three round fight, Osawa once again won via decision.

In June 2010, Osawa faced Katsuya Toida at Sengoku 13. In the third round, the bout was ended after accidental kicks to the groin by Toida. There is some confusion over the official result of this bout. The result is regarded as either a "no contest" or a victory for Osawa by disqualification due to more than 50% of the fight being completed.
