Model Factory Hiro is based in Tokyo, Japan. It’s perhaps not the best known kit manufacturer in the world, but from what I’ve seen of their kits, they are probably one of the best. Despite using methods more usually associated with ‘garage kit’ production the kits are of the highest quality.
Despite being a relatively small manufacturer they produce a huge array of kits, and also create detailing parts, paint and reference works.
HobbyLink.tv recently filmed a fascinating factory tour which you can see in the two videos below.
