The head of one of Japan's most recognizable drinks companies has resigned after police opened an investigation into whether he broke the country's strict cannabis laws by purchasing supplements suspected to contain THC.
Takeshi Niinami, 66, stepped down as chief executive of Suntory Holdings following reports from Tokyo media that he is under investigation for allegedly buying products containing THC — the psychoactive compound found in cannabis. Niinami has denied any wrongdoing and told the company he genuinely believed the supplements he purchased were legal.
A Company With Deep Western Roots
For those who may not immediately recognize the Suntory name, the Japanese conglomerate has a much wider reach than most people realize. The company owns some surprisingly familiar brands across the Atlantic, including Ribena, Lucozade, and the well-regarded Scotch whisky distillery Bowmore. Suntory is also the parent company of Beam Suntory, the spirits group behind Jim Beam and Maker's Mark, making it a significant player in the American bourbon and whisky market.
What the Investigation Is About
Japanese law around cannabis remains among the strictest in the developed world. Unlike the United States, where THC products are legal in many states for both medical and recreational use, Japan maintains a near-total prohibition on cannabis and its derivatives. Even trace amounts in supplements can trigger serious legal consequences.
Niinami is suspected of obtaining products that contained THC, putting him in potential violation of those laws. The investigation was enough to prompt his departure from the top job, regardless of how the legal process ultimately plays out.
The Company's Response
Suntory's president, Nobuhiro Torii, did not hold back when addressing the situation publicly. Torii stated that Niinami's actions 'fall short of the qualities required' of a leader, a pointed remark that made clear the company viewed the situation as a serious breach of the standards expected at the executive level.
The swift resignation signals that Suntory was not willing to let the investigation drag out while Niinami remained in the top seat. Japanese corporate culture places enormous weight on the conduct of senior leadership, and the reputational risk of an ongoing criminal probe against a sitting CEO is something most major Japanese firms move quickly to contain.
Niinami's Position
Despite stepping down, Niinami has been clear that he does not believe he did anything wrong. His position is that he purchased the supplements under the assumption they were legal, which raises questions about where and how the products were obtained and whether they were clearly labeled in a way that would have indicated their THC content.
That argument — that the buyer was unaware of the illegal ingredient — is not uncommon in cases involving supplements, where labeling can sometimes be misleading or incomplete, particularly when products are purchased abroad or through less regulated channels.
What Comes Next
The investigation remains open, and the legal outcome for Niinami is still unknown. His resignation removes him from the immediate spotlight in a corporate sense, but it does not shield him from whatever the police inquiry ultimately concludes.
For Suntory, the priority now shifts to leadership stability and protecting the reputation of a company that operates on a genuinely global scale. With bourbon, Scotch, energy drinks, and soft beverages all under its umbrella, the company has a lot to manage beyond the headlines coming out of Tokyo.
The case is a reminder that executive conduct — even in personal life — carries significant weight at the top levels of major corporations, and that the gap between what is legal in one country and illegal in another can catch even experienced business leaders off guard.
