Management principle

Message from the Representative Director.

We would like to thank you for your patronage.

We are proud to say that Our product is the ultimate in traditional craftsmanship, which can only be completed after about 5,000 processes,integrating techniques unique to Japan such as goldsmithing, woodwork, Kyoto textiles, braided cord, and leather crafts.

Each of the 5,000 steps in the processes is filled with the precious thoughts and spirit of the craftsmen.

In this age of mass production, we feel great joy and pride in being able to create the one and only treasure of a lifetime for children who are born and have been born and we strive to create products every day, believing that what lies ahead will be the “smiles” and “impressions” of many people.

We will always keep the spirit of challenge in mind, and in order to provide even better products, we will continue to work diligently to manufacture products by further refining our original methods and sophisticated technology, while inheriting the technology from the first generation.

We look forward to your continued support and patronage.
