Japan is undergoing significant regulatory and structural changes within its alcoholic beverage market. The government has implemented a liquor tax reform designed to unify tax rates across beer, Happoshu, and ‘new genre’ beverages to 54.25 yen per 350ml to restore fairness and reduce price disparities.

Parallel to these tax changes, the Japan Fair Trade Commission (JFTC) has launched a compulsory criminal investigation into four major manufacturers—Asahi, Kirin, Suntory, and Sapporo—which together control approximately 90% of the domestic market. The companies are suspected of violating the Antimonopoly Act by coordinating shipment prices for beer, quasi-beer (happoshu), and third-category beverages over several years.

Investigators conducted raids on company headquarters in Tokyo using court-issued warrants to seize evidence. The probe focuses on whether sales executives used informal meetings, such as the ‘Ichimokukai’ held after regular Brewers Association of Japan gatherings, to align the timing and scale of price increases. Specific instances of interest include synchronized price hikes for beer and chu-hi (low-alcohol canned cocktails) occurring in October 2022 and April 2025.

While some sales representatives have reportedly denied the allegations to wholesalers, multiple sources indicate that some company officials have admitted to price coordination during questioning by authorities. Asahi and Kirin have confirmed their cooperation, though leadership has previously denied awareness of such agreements. The JFTC is considering criminal referrals to prosecutors given the potential impact on consumers in a market valued at approximately 1.6 trillion yen annually.
