Sunrise Inc. is a Japanese animation studio.
Found in 1972 as Sunrise Studio YK, the studio soon carved out an impressive reputation for robot anime, including working on numerous shows with Toei. They really made their name with Mobile Suit Gundam in 1979, becoming the go-to studio for the long-running franchise. They eventually became part of Bandai, though the company is still nominally separate.
Sunrise produced the animation for Machine Robo Rescue.
