Ninomiya was born in Kumamoto Prefecture on April 11, 1969. After graduating from the University of Tsukuba, he joined Urawa Reds in 1992. In 1992, he moved to Uruguayan club Danubio on loan. In 1993, he returned to Urawa Reds and played many matches as a forward. In 1994, he did not make any appearances and so he moved to Regional Leagues club Prima Ham Tsuchiura (later Mito HollyHock). In 1997, the club was promoted to Japan Football League. He retired at the end of the 1997 season.
After retirement, Ninomiya started his coaching career at Mito HollyHock in 1998. He served as coach under manager Toshiya Miura. In 1999, he succeeded Miura as manager. The club finished in 3rd place in 1999 Japan Football League and was promoted to J2 League. However, he did not have a license to manage in the J.League, and returned to being a coach. He left the club at the end of the 2000 season.
