Metal House is a small Tokyo based family firm still making tin plate robots as it did back in the 1960s. They made most (if not all) of the SH Horikawa robot models and also made robots for Daiya, Yonezawa and Linemar. The company was established in the 1930s and originally called ‘Marumiya’.

Robot Family

The Piston Robot III is a relatively modern design. 1990s or early 2000s, I’m not sure. You can tell by the fact it takes AA batteries rather than the old D-cells. Early ancestors include S.H. Horikawa piston robots from the late 1970s which had translucent heads as well as chest windows. The circular, ringed chrome ears on this version III have design similarities to these earlier models.

Five Retro Toy Robots

Take a look at 5 toy robots from my collection. In this video I showcase these awesome battery powered tin toys so you can see what they do and how they move. They walk, they shoot, the spin around with flashing lights, robot sounds and puffing smoke effects. PREPARE FOR EPIC! The five toy robots include ‘Space Evil Robot’ and ‘Piston Robot III’ made by Metal House in Japan. ‘Chief Robotman’ and ‘Chief Smoky’ are reproductions made by the Haha Toy Factory. The other Piston Robot is the oldest in the group and was manufactured in Taiwan by SJM I believe. It’s a super high quality copy of a Horikawa design but with taller metal legs (which I think looks a lot better tbh).
