Craftsmanship
A Craft Passed Down Through Five Generations
Certified Skill, Recognized Tradition
Our workshop was founded in 1886 in Nagoya, and later moved through Sendai before establishing its current workshop in Tokyo.
For over 140 years, the craft of hand-carved hanko has been passed down through five generations of the same family. Today, the workshop is led by the fifth-generation master craftsman, continuing the techniques and values inherited from those before him.
One Name, One Artisan, One at a Time
Every hanko is made only after an order is placed. A single craftsman carefully carves each character by hand, adjusting balance, depth, and line thickness to suit both the name and the material.
No two stamps are ever exactly the same. This is not a product made to be replaced. It is made to be carried — and used — for a lifetime.
Materials Chosen with Care
We work with natural materials such as wood and black buffalo horn, selected for their durability and stamping quality. The buffalo horn used in our hanko is sourced exclusively as a by-product of the livestock industry. No animals are harmed specifically for the purpose of producing hanko.
Our craftsman has worked with trusted suppliers for decades to ensure that materials are handled responsibly and with respect — a standard that is deeply important in Japanese craftsmanship.
A Living History
In 1945, during the war, the third-generation master returned home and rebuilt both his life and the family workshop — so the craft would not be lost.
The tools, the hands, and the quiet dedication you see today belong to the same lineage. Unchanged in spirit, refined through time.
Carried Forward by the Fifth Generation
Today, the workshop is led by Shohei-san, the fifth-generation master.
He carries forward 140 years of tradition, shaping each hanko by hand — one at a time.
This is not just a stamp. It is a story still being written.
