Prepare tofu and inari, and remove excess moisture.
Mash the tofu finely and stir-fry in a pan to evaporate the moisture.
Mix the stir-fried tofu, a pinch of salt, vinegar, and sugar into the rice.
Open the inari pouch and fill it with the rice, shaping it.
Finish by topping with seaweed or sesame seeds as desired.
