Nomura means 'field village', or 'wilderness field' and is also known as TN. It was one of the biggest and most prolific of all post-war Japanese toy makers and was specialized in mostly mechanical and wind-up friction toys featuring very creative designs.
Nomura started manufacturing tin toys in the late 1940s and quickly dominated the marketplace. They made orgiginal colorful tin toy cars and other vehicles that represented the new 'role model' of Western technology and Japanese spirit: Wakon Yosai.
Nomura had long been at the top of their game when Astro Boy and Tetsujin (Iron Man) 28 arrived to herald the age of homegrown SF robots, and tinplate was the perfect material to render them in three dimensions. Robby the Robot from Forbidden Planet flew in from the USA to create a perfect storm, and Nomura was right there at the right time an place.
