is a Japanese former professional baseball left-handed pitcher who is a free agent. He has previously played in Nippon Professional Baseball (NPB) for the Fukuoka SoftBank Hawks and Tokyo Yakult Swallows.

Career Yamada played his first season in the NPB with the Hawks going 4-4 and a 4.60 ERA, striking out 44 over 59 innings. At the end of the season he joined the Brisbane Bandits inaugural roster and was reported to try to learn a slow curve during the season.

Yamada pitched his first shutout for the Hawks on May 20, 2011 over the Hanshin Tigers, letting in only 4 hits over 9 innings of work. He finished the 2011 regular season 7-7 with a 2.85 ERA. In the 2011 postseason, Hiroki picked up the win in Game 5 of the Japan Series, throwing 6 shutout innings. The Hawks would go on to win the Series against the Chunichi Dragons 4-3.

On November 11, 2017, the Fukuoka SoftBank Hawks traded Yamada to the Tokyo Yakult Swallows for free of charge.
