Toaplan Co., Ltd. was a Japanese video game developer based in Tokyo responsible for the creation of a wide array of scrolling shooters and other arcade video games. The company was founded in 1979 but its gaming division was established in 1984 by former Orca and Crux employees, who wanted to make games, after both companies declared bankruptcy. Their first shoot 'em up game, Tiger-Heli (1985) on arcades, was a success and helped establish Toaplan as a leading producer of shooting games throughout the 1980s and 1990s that would continue to characterize their output.

Though initially exclusive to arcades, they expanded with the Sega Genesis in 1990. The company ceased development of shoot 'em up projects before declaring bankruptcy in 1994. Several offshoot developers such as Tamsoft, Eighting, CAVE, Gazelle, and Takumi Corporation were formed prior to and after the closure, while former members later joined to other studios such as Bandai Namco Entertainment, Capcom, Square Enix and Taito. Toaplan has since earned recognition from critics, being called one of the greatest and most influential Japanese shoot 'em up developers and "master" of the scrolling shooter genre.

Currently their official website is still active and they still license the branding of their products on different kinds of merchandise including t-shirts and limited re-releases of their classics.
