Online Shopping While in Japan
Official online store: http://www.tadafusa.net
Our online store ships within Japan only.
If you place an order while visiting Japan, we can ship your items directly to your hotel. Please include your hotel information in the remarks section when placing your order.
If you use a third-party forwarding or shipping service to purchase from our Japan-only online store, please note that we cannot take responsibility for any issues that may occur, including shipping problems, loss, or damage.
If you would like to purchase our knives outside Japan, please check our list of Foreign dealers. Some of them offer international shipping.
Factory Visit
For safety reasons, the factory is not an area visitors can walk through on their own, so a guided visit is required and offered for a fee.
– Reservations are required at least three days in advance via our website or by email.
– Fee: JPY 1,100 per person (tax included)
– Duration: around 30 minutes (may vary depending on factory operations)
– Available for small groups of around five people
– Only the processes running at the time will be shown
– Tours may be conducted in Japanese if the staff member in charge is unavailable.
– Tours may not be available on certain days, depending on factory conditions
Since many visitors come to our shop to purchase knives, we kindly ask that factory visits be for shopping purposes rather than for sightseeing only.
During the summer months, temperatures inside our factory can become extremely high. For the safety and comfort of our visitors, factory visits may not be available depending on the weather conditions.
Workshop Classes in Sanjo
Hands-on workshops are not currently available at TADAFUSA.
If you would like to experience a hands-on workshop, Sanjo Blacksmith Dojo is a great option, located about 10 minutes from our shop by car.
One of the workshops they currently offer is knife making. You can experience almost every step of the knife-making process with guidance from skilled craftsmen. Many visitors from overseas have participated in their workshops before or after visiting our shop. Why not make a one-of-a-kind knife yourself?
Learn more about their knife making workshop here.
