Primary baseline food shares will be recalibrated as standardized regional grocery baskets are established.

Japan's food expenditure model incorporates a standard baseline of two restaurant meals per week. However, actual living expenses often lean higher due to two urban realities: ultra-compact apartment layouts (1K/1DK) with minimal kitchen infrastructure, and premium retail pricing on fresh produce. As a result, home cooking offers marginal savings compared to dining out, leading urban workers to rely heavily on prepared meals.
