Japan Raids Big Four Brewers Over Suspected Beer Price Coordination
Japan's Fair Trade Commission searched the offices of Asahi Breweries, Kirin Brewery, Suntory Beer and Sapporo Breweries this week on suspicion they colluded to set the price of beer and other beverages. The Guardian
Together the four brewers control more than 90% of Japan's domestic beer market. Commission Secretary General Hiroo Iwanari confirmed that an investigation had begun. Asahi, Kirin, Suntory Beer and Sapporo said they would cooperate with authorities.
Investigators suspect sales managers and other executives met secretly over a prolonged period to coordinate the timing and scale of retail price increases. The suspected increases ranged from several yen to several dozen yen each time. The focus is coordination of timing and size, rather than one single price.
The four breweries raised prices at the same time in October 2022, October 2023 and April 2025. On each occasion they cited rising costs of materials and distribution. The Guardian
Japan's alcohol sales reached 3.8 trillion yen ($24.3 billion) in 2024, with beer accounting for 30% of the total. Shares in Asahi, Kirin and Sapporo fell after the Wednesday raids. Suntory is not publicly listed. BBC
Suntory said in a statement that it was undergoing an on-site inspection by the Fair Trade Commission. ABC News Three months before the October 2026 beer raids, the Commission raided six Japanese ice-cream makers over allegations of operating a cartel, a secret agreement to limit competition.
The broader context here is enforcement in a highly concentrated consumer market. An oligopoly, where a few firms dominate sales, does not by itself break Japan's anti-monopoly law. Parallel price moves are not proof either, since firms can react separately to the same cost pressure like runners starting after hearing the same gun. Investigators will need to establish contact, exchange of sensitive price intentions, and alignment of conduct.
Looking at what this means for competition policy, the sequencing is worth attention. A food-sector cartel inspection followed within a quarter by action against brewers controlling more than nine-tenths of domestic beer supply points to sustained scrutiny of pass-through pricing, when higher input costs are passed to shoppers, during an inflation cycle. For the brewers, cooperation at the inspection stage leaves the questions of liability, administrative surcharge exposure, or fines, and potential criminal referral still to be decided through the Commission's procedure.
