Suntory Holdings, one of Japan's leading beverage companies, publicly stated that it sees deficiencies in Mr. Shiina's qualifications amid ongoing investigations. The company did not elaborate on the specifics surrounding the scrutiny over Shiina's credentials. However, it's clear that Mr. Shiina, who has links to the beverage giant, faces mounting pressure over allegations of his credibility and professional conduct.

In Japan, personal integrity and honor are important cultural values. Any hint of professional misconduct or disqualification can draw considerable attention and quickly turn into a social issue. This explains why news like this arouses much interest within the Japanese public. Consumers may even boycott a company over ethical concerns linked to its affiliated individuals.

Like in Japan, professional credential issues face serious criticism in the U.S or EU. It often results in the public demanding full disclosure, regulation tightening, or even punitive measures against the individual involved. However, the strong cultural emphasis on honor in Japan may lead to a more pronounced public reaction.
