Suntory CEO Takeshi Niinami has resigned after telling the company he was under police investigation over a supplement he believed was legal. Tokyo Shimbun reported that authorities probed whether cannabis-component supplements were sent to his home; police questioned him and searched his Tokyo residence. No illegal possession or use has been confirmed. Niinami informed Suntory of the probe on 22 August and stepped down on 1 September, the firm said. (Suntory CEO resigns.)
What Investigators are Looking at
Japanese media reports say the investigation centres on products allegedly containing THC, a prohibited cannabis ingredient in Japan. The Financial Times also reported that officers searched Niinami’s home and conducted a urine test; Niinami has denied wrongdoing and said he thought the product contained legal CBD.
Company Response and Leadership Context
Suntory President Nobuhiro Torii praised Niinami’s growth record, calling his leadership “bold” and “decisive,” while expressing regret over the departure. Niinami, 66, became the first non-family head of Suntory in 2014 after leading Lawson, and he also chairs the Keizai Doyukai business lobby and has advised Japanese prime ministers.
Under his watch, the group expanded globally across whisky and soft drinks, including Orangina; Suntory also grew after acquiring the maker of Jim Beam for $16 billion in 2014. (Suntory CEO resigns.)
Why This Matters in Japan
Japan enforces strict drug laws and corporate leaders have previously faced swift consequences for suspected violations. The case underscores reputational risk around supplements as THC rules tighten, even while CBD products occupy a legally sensitive space. Suntory said it was notified of the probe in late August and held internal hearings before the resignation.
The Road Ahead for the Drinks Giant
Suntory, known for global spirits (Jim Beam, Laphroaig) and soft drinks, now navigates an abrupt leadership shift as it stresses due diligence in wellness products. The company has not announced a permanent successor.
