Claustrum is the metal item brand of Steel Inc. in Ginza, Tokyo. This brand develops simple yet groundbreaking products that are based on functional research.
Inside the Brand
Ground-breaking metal items from Ginza Tokyo
All of Claustrum’s items feature brand new functions that can be found nowhere else, including one-hand operation and smart motion. In addition to the physical realm, we also explore functions in terms of aesthetics, intellect, society, economy and other fields.
The results are put through a repeated cycle of trial manufacture, experiments, and trial use at the Ginza Factory until they can be realised in the simplest fashion possible.
As we accumulate experience in this way, we product new mechanism, construction methods and surface processing methods that are truly unique.
