The focus is on maintaining the health of inmates rather than indulgence. Each meal is carefully portioned to provide adequate calories and nutrients based on guidelines set by the Japanese Ministry of Justice. The ingredients used are often seasonal, ensuring freshness and variety.
Breakfast might include rice, miso soup, a small portion of pickled vegetables, and sometimes a slice of grilled fish. Lunch and dinner are similar, with rice as the staple, accompanied by a protein source like tofu, fish, or chicken, and a couple of vegetable side dishes. The food is cooked in a simple manner, often steamed or boiled, with minimal use of oil and seasoning.
Inmates eat their meals in their cells or designated dining areas, and the food is served on trays with each portion separated. The diet in Japanese prisons is strict, emphasizing moderation and discipline, reflecting broader cultural values around food and health.
