What is Tendon?
In Japanese cuisine, Tendon is a dish that combines tempura (deep-fried battered seafood or vegetables) with Donburi (a bowl of rice). The word “Tendon” is a blend of “Tempura” and “Donburi“, and it features a serving of hot rice topped with various pieces of crispy tempura, typically shrimp, fish, and seasonal vegetables like sweet potato or pumpkin.
History of Tendon, a beloved commoners food in Japan, is known to date back to the Edo era (1603–1867).
Our brand name, “Kohaku (amber)”, embodies our commitment to “capture the genuine flavors of ingredients while embracing the history and tradition of Tendon“, just like ambers encapsulating the integrity of ancient plants and other creatures. A bowl of our supreme tendon epitomizes the spirit of “visiting old, learning new”. TENDON KOHAKU is a proud testament to Japan’s delectable tradition of Tendon.
