Ichiju Sansai One Soup Three Sides Meal Structure
Origin
Japan — documented in Heian period court documentation; formalised as household standard through Muromachi and Edo periods; enshrined in washoku UNESCO Intangible Cultural Heritage designation (2013)
Description
Ichiju sansai (一汁三菜, 'one soup, three sides') is the foundational structural principle of the Japanese meal — a framework that has governed washoku preparation for over a thousand years. The format consists of: gohan (steamed white rice, the main staple), one soup (typically miso soup or clear broth), one main dish (usually protein-based: fish, meat, or tofu), and two side dishes (typically one cooked vegetable and one pickled preparation). This is the minimum structure; formal kaiseki expands to ichiju sansai or further, but the household meal revolves around this core. The principle ensures nutritional completeness, seasonal variety, and the correct flavour contrast between rich (main), light (soup), and refreshing (pickles).
