Oguchi was promoted in 2003 alongside Yuji Naka and Toshihiro Nagoshi, based on the success of arcade games that used cards. Due to Hitmaker being one of the few profitable studio of Sega, Oguchi had the freedom to pursue businesses outside of video games, and invested into the darts business. Hitmaker was involved in the establishment of DARTSLIVE Co., Ltd. which produces electronic darts machines, and a darts bar called Bee was opened in Shibuya in 2002.
