Nutrition Calc Japan (MEXT8th)

Menu planning and nutrition calculation for dietitians working with Japanese food data. The complete Standard Tables of Food Composition in Japan — 8th revised edition, amended 2023 (2,538 foods × 54 components) — built in and fully offline.

■ Complete MEXT food tables (Japanese)
Search by food code, name, or kana. Energy, protein, fat, carbohydrates, fiber, vitamins, minerals, and salt equivalent. Trace / estimated / unmeasured markers are preserved as published, and foods missing from a total are always flagged.

Build dishes (recipes), place them on a menu, and totals scale by servings automatically. Supports sub-recipes and order-quantity calculation from refuse percentage.

■ Dietary Reference Intakes for Japanese (2025)
Reference values (EAR / RDA / AI / DG / UL) looked up by sex, age group, and physical activity level, with at-a-glance adequacy judgment. Includes additions for pregnancy and lactation.
