OSAKA -- Sushiro, Japan's leading conveyor belt sushi chain, will raise prices on its 100-yen plates after nearly four decades due to rising costs and the weak yen.
"Because about 70% of the raw materials are imported, the weak-yen environment has been harsh," Koichi Mizutome, president of Sushiro parent Food & Life Cos., said Monday. Japan's currency has depreciated to 20-year lows against the dollar in recent weeks.
