Japanese Cooking

About Us

Welcome to Kai House Japanese Cooking and the culinary wonders of washoku, Japanese cuisine! We have two studios conveniently located in central Tokyo. The Kai House studio in Iwamotocho, near the tourist spot Akihabara, is only a 10-minute train ride from Asakusa, another popular spot. And the other studio AMY’S in Minamiaoyama is only a 5-minute train ride from Shibuya Station.

Our classes are organized by KAI Corporation which was established in 1908 and is Japan’s largest producer of kitchen knives. As you might have guessed from our long history, our ability to produce knives can be traced back to the making of katana, a samurai warrior’s sword.

Washoku has been recently added to UNESCO’s Intangible Cultural Heritage list. Washoku embodies Japanese people’s deep respect toward nature and the four seasons. This also includes the importance they place on the sustainable use of local produce.

Let us guide you on the traditional Japanese style of preparing and eating delicious dishes.


Team-Building Cooking Classes

Perfect for strengthening a sense of camaraderie, our team-building cooking classes offer an out-of-the-ordinary experience for novice and seasoned cooks alike.

Your staff will cook washoku, the internationally popular Japanese cuisine. The collaborative nature of cooking will help train your team and enrich your company’s future long after leaving the kitchen. For bookings, please choose from the two courses below.

Cook Off Course

Your staff will be divided into groups to compete with each other on the finish of washoku dishes. This will heighten competitiveness between the groups, whilst increasing team spirit. Winning or losing, best of all is the joy of cooking savored as one. Menu: Popular Japanese Menu

Challenge Course

Food brings out the best in people, especially when cooked together. In this course, your staff will work in groups in a comfortable setting away from a work environment to enjoy cooking washoku. Our Challenge Course offers the opportunity to build friendships and create an open atmosphere. Menu: Choice of the Popular Japanese Menu or the Seasonal Japanese Menu

Available from 11:00 a.m. to 9:00 p.m. weekdays except certain holidays. For inquiries, please contact us.
