Kaiyodo (海洋堂, Kaiyōdō) is a Japanese company which manufactures figurines and garage kits. Its headquarters is in Kadoma, Osaka Prefecture. While the company mostly focuses on anime related characters, it recently has acquired other licenses, e.g. King Kong, and some Godzilla characters.

Kaiyodo was originally a small shop in Japan, but grew into a famous company over the years, leading them to sell collectables worldwide. One of their most famous sculptors is Bome, who is most well known for his Mon-sieur BOME collection. In recent years, his figurines have become well known and sought by collectors, and his works have been displayed on a worldwide scale at conventions, including Paris, Tokyo etc.
