Chicken and eggs are long regarded as affordable staples for budget-conscious consumers in Japan. Chicken prices hit a record high in Japan, with the average retail price of chicken thighs in June 2026 at 155 yen (about $1) per 100 grams, the highest level since comparable records began in 2003, according to Mainichi.jp. The rise in chicken prices has forced a growing number of restaurants and food manufacturers to either change their menus or raise prices, according to Mainichi.jp. Kiyoken Co. replaced 'chicken in chili sauce' with 'shrimp in chili sauce' in its 'Yokohama fried rice' bento on June 1, 2026, according to Mainichi.jp. Some businesses are changing menu items despite risks to customer loyalty.
