As manager As coach Tomohiro Nioka (二岡 智宏, born April 29, 1976, in Miyoshi, Hiroshima, Japan) is a Japanese former professional baseball player.

On November 14, 2008, Nioka and Masanori Hayashi were acquired by the Hokkaido Nippon Ham Fighters for Takahito Kudo and Micheal Nakamura.

It was reported that possible destinations for Nioka might be the Chicago White Sox, Toronto Blue Jays, Tampa Bay Rays, San Francisco Giants, or St. Louis Cardinals.

In July 2008, the Japanese tabloid weekly Josei Seven reported, with pictures, that Nioka, who is married, had gone to a love hotel with TV announcer Mona Yamamoto.

The two met by chance at a gay bar in Shinjuku ni-chōme, Tokyo and, according to the newspaper, traveled to the hotel after drinking and conversing for several hours.
