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.
Revoltech (リボルテック?) is a portmanteau for "Revolver Technology," in reference to the unique "Revolver Joint" articulation which all of the figures in this particular series utilize. This gives the figures a wide range of motion and stability, allowing for many dynamic and varied poses.
The subject matter for the Revoltech line can be broadly split into four categories—Real Robot, Super Robot, Humanoid and Creature. Thus far, robots and characters from anime, video games, manga, tokusatsu, film and television have been covered.
