We do have a large retail store in the Shinjuku area of Tokyo.
You can place an order in our webshop and have the items ready for collection in our store at a specific date. Let us know if you are interested and we'll give you further instructions.
This link should take you directly to the Google Maps Street view in front of the building where the store is located. If you look up you will see the red Isami logo outside the building. There usually is a small sign standing by the street to let passersby know that the Isami store is there.
Here's the address and contact information:
