Kuramochi & Co.
20 years in operation (1950–1970)
About Kuramochi & Co.
Kuramochi produced battery-operated tin toys and robots for the export market. Their 'CK' trademark — not the 'KO' mark, which belonged to Yoshiya — appears on tin robots, cars and novelty toys collected as examples of the creative and colorful Japanese tin toy tradition.
History of Kuramochi & Co.
Kuramochi, trading with the "CK" mark, was one of the larger Tokyo tinplate houses and had a longer history than most of the postwar export firms — it had been active before the war and resumed afterwards. Its postwar output covers friction cars, battery-operated novelties and space toys, including tin robots.
The robots and space toys are the collected end. Japanese tin robots of the late 1950s and early 1960s are among the most valuable postwar toys in the world, and CK-marked pieces sit within that market alongside those of Nomura, Horikawa and Masudaya.
Documentation for Kuramochi, as for the whole Tokyo tinplate trade, is thin, and trademarks were shared, licensed and confused. Kuramochi is frequently and wrongly credited with the "KO" mark, which belonged to Yoshiya; a CK-marked toy is best described as such rather than confidently assigned.

Identifying & Dating Kuramochi & Co. Toys
- Look for a "CK" mark, sometimes in a circle or diamond, lithographed on the base with "Made in Japan". Do not confuse it with Yoshiya's "KO".
- "Occupied Japan" markings date a piece to 1945–1952 and are worth a premium.
- Importer marks — Cragstan, Rosko, Linemar — may appear instead of or alongside the maker's mark and identify the distributor, not the factory.
Collector's Notes
- Robots and space toys are the high-value items and must be complete: antennae, arms, battery hatch, and any accessory pieces, all of which are commonly missing.
- Battery corrosion is the standard destroyer of this material. Open the compartment and look before buying.
- The Japanese tinplate robot market has serious money in it and correspondingly serious reproductions and restorations. Buy from specialists for anything expensive.
