The makisu is a kind of small bamboo mat made by weaving fine bamboo stems with a cotton string. Makisu is used mainly for the preparation of maki sushi, but also tamagoyaki or to drain the leaves of spinach after cooking.
If you wish to buy these utensils, for your preparations or as a gift, you will find your happiness in the artisans shops of the Kappabashi district in Tokyo.
The makisu mat will allow you to wrap the Maki during preparation. You can also use it to prepare vegetables like spinach or compress tamagoyaki (Japanese omelette) to give it a square shape.
