企画デザイン工房 戦船

Ikusabune was established on March 28, 1991 and headed by Toshio Akashi (赤司俊雄). The company's focus was on planning, CG design, and animation; programming and sound were usually handled by a co-developer or outsourced.

It merged with Seta in April 2004, with Ikusabune's development business becoming Seta Visual Contents Department (株式会社セタ 映像コンテンツ事業部). Seta was shuttered by its parent company Aruze on February 9, 2009, including the former Ikusabune studio.
