Remove moisture from the tofu and mash it finely.
Lightly stir-fry the mashed tofu in a pan to evaporate the moisture.
Add salt, vinegar, and sugar to the stir-fried tofu and mix well.
Mix the prepared tofu and the measured amount of sushi seasoning evenly into the rice.
Blanch the inari (fried tofu skins) in boiling water to remove oil, then squeeze out excess moisture.
Shape the seasoned rice into appropriate portions and stuff into the inari pockets to finish.
