木綿豆腐 (cotton tofu) - как раз таки твердый, а не очень мягкий.

Although drained and pressed, this form of fresh tofu retains a high moisture content. It has the firmness of raw meat and bounces back readily when pressed. The texture of the inside of the tofu is similar to that of a firm custard. The skin of this form of tofu retains the pattern of the muslin used to drain it and the outside is slightly more resistant to damage than the inside. It can be picked up easily with chopsticks
