In a stunning turn of events, the long-standing CEO and Chairman of Suntory, one of Japan’s most influential beverage giants, tendered his resignation amidst a police investigation into supplements allegedly containing THC, a cannabis-related compound. The resignation has shocked both the Japanese business community and international markets, raising questions about corporate governance, leadership accountability, and the fragility of trust in global brands.

The Incident Unfolded

The scandal began when police launched an investigation into supplements imported from the United States. These products were suspected of containing tetrahydrocannabinol (THC), the psychoactive component of cannabis. Authorities searched the CEO’s home in Tokyo and questioned him, though no illegal substances were ultimately seized.

The executive explained that he believed the supplements to be legal health products and even claimed that they had been sent by an acquaintance without his request. Despite this defense, the investigation cast a shadow over his position as the head of a company that represents Japan’s traditional corporate values.

Faced with growing scrutiny, the CEO submitted his resignation. Suntory’s board accepted the decision, stating that although wrongdoing had not been proven, the damage to public confidence and corporate governance standards necessitated a leadership change.

Leadership Legacy and Corporate Culture

The departing chairman was the first non-family leader of Suntory and had guided the company through a period of global expansion. Under his leadership, Suntory acquired major overseas brands and positioned itself as a world-class beverage powerhouse. He was also known as a prominent voice in Japan’s business and political discussions, often advocating for economic reforms and globalization.

However, in Japan’s corporate culture, the perception of impropriety can be as damaging as the act itself. Even unconfirmed allegations are enough to undermine the reputation of a leader. In this case, the mere association with a controlled substance, regardless of intent, was considered unacceptable for the figurehead of a global corporation.

Why This Case Matters

The resignation illustrates several deeper truths about Japanese business culture and international corporate leadership:

  • Accountability Over Intent: Even if a leader insists they had no knowledge of potential wrongdoing, they are expected to step down once public trust is compromised.
  • Corporate Image as Public Trust: Companies like Suntory are not just commercial entities; they are cultural institutions. Any scandal involving top executives threatens to tarnish decades of brand equity.
  • The Fragility of Leadership: A single misstep, even one perceived as minor or unintentional, can undo years of credibility and achievements.

This case serves as a reminder that the higher the position, the greater the responsibility to anticipate and avoid even the perception of misconduct.

My Perspective: The Price of Trust

From my viewpoint, this incident reveals how leadership in Japan extends far beyond business performance. It is deeply intertwined with notions of honor, integrity, and social responsibility.

The former CEO’s explanation—that he thought the supplements were lawful and unsolicited—may hold some truth. Yet in leadership, perception often outweighs explanation. The public does not measure leaders solely by their achievements, but also by the standards of judgment they embody.

Trust, once shaken, is rarely restored quickly. That is why his resignation feels less like an admission of guilt and more like a symbolic act to preserve the company’s honor and protect the reputation of the Japanese business community as a whole.

What Comes Next for Suntory

Looking ahead, Suntory faces the challenge of stabilizing its leadership and restoring stakeholder confidence. The company will need to:

  • Appoint a credible successor who can signal stability and continuity.
  • Strengthen internal compliance measures to reassure both domestic and international markets.
  • Rebuild trust with consumers who may question the ethical compass of the corporation.

The case also signals a warning to other Japanese firms: global expansion brings exposure not only to new markets but also to different cultural and legal risks. Companies must be prepared to scrutinize even personal choices by their executives, as those choices can quickly become corporate crises.

Final Thoughts

The resignation of the CEO of a major beverage maker highlights the fragility of leadership in Japan’s corporate world. Even without proven illegality, the association with a controlled substance was enough to trigger a seismic leadership change.

This episode underscores a universal truth: in corporate leadership, performance can build success, but integrity sustains it. Leaders who forget this balance risk not only their positions but also the legacies of the institutions they represent.
