Toshiro Tsuchida (土田 俊郎 Tsuchida Toshirō?) (born 1964) is a Japanese game director and game producer who currently works for Japanese Social Game company GREE. He formerly worked for Square Enix Co., Ltd. (formerly Square Co., Ltd.). He is most notably credited for creating the Front Mission and Arc the Lad media franchises.
Toshiro Tsuchida worked for Japanese development studios Masaya and G-Craft, the latter of which he founded in 1993 after leaving Masaya. During the development of Front Mission 2 and Front Mission Alternative, Square initiated talks with Tsuchida in an attempt to purchase G-Craft in 1997. As the buyout occurred during Front Mission 2's development, it became the last title with G-Craft credited as the developer.
Tsuchida was also the battle director for both Final Fantasy X and Final Fantasy XIII. As battle director of Final Fantasy X, he pulled away the Active Time Battle (ATB) system, which started with Final Fantasy IV and originally designed by Hiroyuki Ito, replacing it with a more strategic battle system, which is known as the Conditional Turn-Based Battle (CTB) system. He kept Final Fantasy IV in mind when working on Final Fantasy X. Tsuchida was the head of Product Development Division-6 within Square Enix.
