The Japan Fair Trade Commission launched compulsory searches at the four companies’ premises on Wednesday as part of a criminal-style investigation into suspected violations of the Antimonopoly Act through price fixing. The regulator is examining whether the brewers which together command more than 90 percent of the domestic market exchanged information on the timing and magnitude of price hikes for beer low-malt happoshu and third-category beverages. Officials are weighing the possibility of a criminal complaint to prosecutors given the probe’s potential effect on consumers nationwide according to sources familiar with the matter. Industry assessments have long identified the quartet as controlling the overwhelming share of beer and beer-like drink sales.
The four brewers are suspected of having coordinated their pricing strategies since at least several years ago often using meetings that followed gatherings of their industry association. They implemented simultaneous price increases in October 2022 October 2023 and April 2025 each time attributing the moves to higher raw material energy and transportation costs. Sales representatives reportedly met to align on how much to raise wholesale prices which in turn influence retail prices at supermarkets convenience stores and restaurants.
National Tax Agency figures show that domestic sales of beer and low-malt beer reached approximately 1.6 trillion yen equivalent to about 10 billion dollars in 2024. The four companies dominate the sector making any coordinated behavior likely to have broad repercussions for household budgets across Japan. The watchdog’s decision to deploy its warrant-backed search powers marks the first such action against food and beverage firms. A parallel compulsory probe targeted diesel fuel distributors in September 2025 and later produced criminal accusations against five oil companies.
Asahi Breweries Kirin Brewery Sapporo Breweries and Suntory Spirits each confirmed the investigation and pledged full cooperation with authorities. Kirin Holdings stated that its subsidiary was searched on suspicion of a violation of the Antimonopoly Act and that the company takes the matter very seriously. The statement added that Kirin would fully cooperate with the Japan Fair Trade Commission’s investigation and any requests for cooperation.
Shares of Sapporo Breweries fell as much as 3.73 percent Kirin Holdings dropped more than 3 percent at one point and Asahi Group Holdings declined nearly 2.5 percent after the news broke. Suntory Spirits is not publicly listed so its parent company did not see an immediate equity market reaction. Market trading records indicated the declines came as investors weighed possible fines or reputational damage from the antitrust case.
The investigation centers on wholesale shipment prices rather than final consumer tags yet the effects cascade through the supply chain to affect what drinkers ultimately pay. Previous price adjustments by the brewers have drawn scrutiny amid ongoing cost pressures in the industry that have prompted multiple rounds of increases. The Japan Fair Trade Commission has signaled that the scale of the alleged cartel in an essential consumer market warranted the escalated investigative approach. Authorities continue to gather evidence from the raided sites to determine the full extent of any coordination.
