Japan beer giants raided over suspicions they colluded to set the price of beverages

Antitrust regulators in Japan have searched the headquarters of the country's four leading breweries amid allegations that they conspired to fix the prices of beer and other drinks.

Investigators from the Fair Trade Commission inspected the premises of Asahi Breweries, Kirin Brewery, Suntory Beer, and Sapporo Breweries earlier this week. The four companies jointly account for over 90% of Japan's domestic beer sector. Authorities suspect the producers violated the nation's anti-monopoly regulations by coordinating wholesale pricing strategies.

Hiroo Iwanari, the secretary general of the Fair Trade Commission, confirmed that an inquiry is underway but withheld further operational specifics. Representatives for the four brewing giants stated that their firms plan to cooperate fully with the regulatory inquiry.

The investigation focuses on whether the companies formed a cartel that artificially inflated retail prices for consumers buying beverages at supermarkets, convenience stores, dining establishments, and bars, according to the Mainichi Shimbun. Media reports indicate that sales executives from the rival breweries are suspected of holding confidential discussions over an extended timeframe. During these meetings, they allegedly agreed on both the scheduling and the magnitude of price increases, which typically ranged from a few yen to several dozen yen per beverage.

Regulators suspect the manufacturers opted to collude rather than engage in normal competitive pricing, aiming to protect corporate margins against rising expenses. In recent years, beverage makers have repeatedly raised prices for traditional beer and happoshu, a low-malt substitute, attributing the adjustments to growing distribution and raw ingredient costs.

Coordinated price hikes took place across the quartet in October 2022, October 2023, and most recently in April of last year. Local media reported that the watchdog views the case as exceptionally grave due to its broad reach across the consumer economy, noting the probe might ultimately yield criminal charges.

The raids prompted a drop in share prices for all four beverage corporations on Wednesday. The action marks an unprecedented antitrust probe of this scale within Japan's food and drink sector. It follows a similar regulatory raid three months prior, which targeted six domestic ice cream manufacturers facing separate cartel allegations.

Overall alcohol sales in Japan reached 3.8 trillion yen, or roughly 24.3 billion dollars, in 2024 despite long-term declines driven by demographic shifts and evolving preferences among younger demographics. Standard beer generated 30% of those retail figures, while happoshu and malt-free third-category drinks collectively represented 11.9% of the market.
