Bottom Up (株式会社ボトムアップ) was a publisher and developer started by former Natsume employees. Shigeru Okamoto (岡本茂) was the president. [1] [2]

The company filed for bankruptcy on March 31, 2000. [3] The development team [4] and the rights to Golf Shiyouyo were transferred to Korean game company Softmax, which established a Japanese subsidiary on May 1. (Dreamcast Magazine [Vol. 20, 2000/6/9-16], p. 21)
