Hiyayakko

Hiyayakko (冷奴, cold tofu^?) is a Japanese dish made with chilled tofu and toppings.

The choice of toppings on the tofu vary among households and restaurants, but a standard combination is chopped green onion with katsuobushi (dried skipjack tuna flakes) and soy sauce. Other toppings include:

Hiyayakko is also known as hiyakko or yakko-dōfu. Hiya means cold, and yakko refers to the servants of samurai during the Edo period in Japan. They wore a vest on which the "nail-puller crest" was attached, on the shoulders; therefore, cutting something (e.g. tofu) into cubes was called "cutting into yakko" (奴に切る, yakko ni kiru^?). "Hiyakkoi" or "hyakkoi", the Tokyo dialectal term equivalent to the standard Japanese "hiyayaka" (冷ややか^?), is also a possible etymology.

In the Tofu Hyakuchin (豆腐百珍^?), it is said that hiyayakko is so well known that it needs no introduction.
