From Japanese Restaurant Chains Face High Costs Due to Leafy Green Shortages

How could the persistent lettuce supply shortage affect MOS Food Services' menu offerings?

Likely What happens if… A possibility worth considering, not a forecast.

Lettuce shortage may force Mos Food Services to change menu ingredients Due to a supply shortage caused by poor weather, leafy green prices in Japan have soared, with lettuce retail prices reaching ¥1,143 per kilogram between October 5 and 7. Because the shortage is expected to continue at least through the end of the month, MOS Food Services, which operates Mos Burger, is considering changing the vegetables used in some of its menu items if the green leaf lettuce supply remains unstable. This operational change would be a direct response to the difficulty in securing a stable supply of the required ingredients.

Why it matters

For MOS Food Services, the primary concern is maintaining the quality and consistency of its menu offerings while managing rapidly increasing input costs. If the shortage persists, the company may be forced to substitute key ingredients, which could alter the consumer experience and require adjustments to production and sourcing logistics.

This issue is not isolated to MOS Food Services. Major restaurant chains across Japan, such as the Royal Host restaurant chain, have already switched vegetables used in set meal salads and side dishes from lettuce to cabbage and kale. This indicates that the supply instability and high prices for leafy greens are a widespread industry challenge in Japan.
