Spending some of his early childhood in Australia, Masahito Kohiyama returned to his native Japan at age six and became a star pitcher in college, winning 19 games in the Tokyo Big Six University League. He was 2-0 with a 2.38 ERA in the 1991 Intercontinental Cup, helping Japan win Silver. He fanned 28 in 22 1/3 IP to finish second in the Cup in Ks behind Dae-sung Koo. A member of the Japanese team in the 1992 Olympics, he was a first-round draft pick that year by the Yokohama BayStars. Kohiyama had a respectable rookie campaign for Yokohama in 1993, going 3-9 with four saves but with a 2.99 ERA (and 2.99 RA) and 85 strikeouts in 99 1/3 IP. Masahito slipped to 2-3, 4.01 his second season, walking 41 in 58 1/3 innings. In 1995, he fell further, going 0-1, 7.84 for the BayStars and issuing 19 free passes in 20 1/3 innings. Over the next two seasons, he pitched just seven innings for Yokohama, allowing 13 runs, 13 hits, 6 walks and striking out eight. After not appearing at all for the 1998 BayStars, Kohiyama had 20 games in 1999 and was a respectable 4-1, 3.77, having the third-lowest ERA of their relievers. He only pitched in 11 games over the next two years and finished his Nippon Pro Baseball career at 9-14 with four saves and a 4.30 ERA. He pitched for the China Trust Whales of the Chinese Professional Baseball League after leaving Japan, going 7-6 with a 3.77 ERA in 2002.
