We resonate with the spirit of "CRAFT SAKEWEEK 2026" to "rediscover Japanese culture and connect it to the future," and have decided to open a restaurant and operate a retail booth on this occasion.

At the restaurant, we will collaborate with "Kudan", a renowned establishment in Gakugei-Daigaku, Tokyo, known for its homemade oden and sake. For five days, from April 21 (Tuesday) to April 25 (Saturday), we will offer a special limited-edition menu for this event that makes full use of "SIIDA®︎"'s three unique and flavorful dashi types – 〈焚 (HUN)〉, 〈燻 (KUN)〉, and 〈酵 (KOU)〉 – as well as the dashi lees.

Additionally, we will set up a retail booth where you can see and purchase "SIIDA®︎" dashi packs, which are usually sold exclusively online. At the venue, an experience corner will be available to compare the unique "aromas" of the three types of dashi. You can enjoy the world of "SIIDA®︎", which adds depth to everyday cooking, through your five senses.
