Neptune Limited (株式会社ネプチューン Kabushiki-gashia Nepuchūn?) is a Japanese video game developer founded in 1998 by Hiroshi Nakajima and is based in Taito, Tokyo, Japan. The company works closely with Forcefield Holdings, and is best known for developing the Baku Baku Carnival, eXu and RX Racing series, as well as assisting Forcefield Holdings with the Pulse, Wrigley and Zyntic series.


Neptune was founded in July 1998 as an electronics manufacturer, and would assist Forcefield with the Q-Bee Pocket, a successor to the Q-Bee programmable calculator. Neptune would later assist the company with development of StarCore Plus, as well as developing the Forcefield Neptune arcade hardware. Many of the company's employees were from Forcefield, who left prior to the company's financial struggle during the late 1990's.

The company produced their first video game, Action Kung-Fu, for their Neptune N-12 hardware in December 1998, and would later shift focus into developing video game hardware and software, and continues to work alongside Forcefield Entertainment in the present day.
