A Precious Craft Preserved in Modern Tokyo
In the vibrant district of Okachimachi, where Tokyo’s traditional commerce and culture flourish, stands “Sano Inbou,” a venerable establishment preserving the art of Japanese seal making. With over 90 years of history, this family business offers a rare glimpse into an essential element of Japanese cultural identity that remains relevant in contemporary society.

Excellence in Tradition Since 1932
The history of Sano Inbou dates back to the Showa era when it was established in 1932 as a specialized shop for seals and printing. Through turbulent times, including World War II, the Sano family has preserved the craftsmanship of making hanko—seals that have functioned as legal signatures in Japan for centuries.
Craftsmanship in Every Seal
What distinguishes Sano Inbou is their unwavering commitment to traditional craftsmanship. Each seal is meticulously finished with techniques backed by tradition. The artisans transform materials such as animal horn and boxwood into distinctive seals that beautifully express the essence of the owner’s name in kanji characters.
Visitors can witness the remarkable precision involved in the creation process, from the initial design consultation to the final carving that demands absolute accuracy. The carving techniques, passed down through generations, produce seals that leave clear and distinct impressions for decades.
A Cultural Souvenir Beyond the Ordinary
Visiting Sano Inbou offers a deep cultural immersion. Japanese seals are still used for important documents, banking transactions, and official procedures. They proudly speak of creating “seals that become lifelong companions,” emphasizing the personal connection between Japanese people and their hanko.
Located at the intersection of Kasuga Street and Kiyosubashi Street, the shop is easily accessible to tourists visiting the Okachimachi area, known for its jewelry stores and vibrant market atmosphere.
