The Kobayashi Pharmaceutical Koji Incident

The recent Kobayashi Pharmaceutical Koji incident has escalated tensions following revelations of inconsistencies in the administrative documents released by Osaka City. The company, known for its safe food products, has raised alarm regarding contradictions concerning the identification of the harmful mold species, Penicillium adametzioides, at its former Osaka factory.

Timeline of Events

On April 19, 2026, Osaka City requested a test to analyze certain wipe samples from the old Osaka factory, with reference number R6-1007. However, before the results of this analysis were made public on December 4, there seems to have been a premature confirmation of the identification of the mold in question. A formal internal review of the city's records indicates that there was no conclusive decision on the identification by May 28, 2026, which contradicts the claims made shortly after.

On May 29, during the third council meeting addressing food poisoning measures related to Kobayashi Pharmaceutical's koji products, documentation stated unequivocally that the isolated mold had been confirmed as Penicillium adametzioides through genetic testing. This claim raised eyebrows, especially since there was no actual documentation verifying that such identification had been established prior to the announcement.

The contradiction itself appears stark: from the time the city requested the testing in mid-April until the formal results were issued in early December, the city had publicly asserted the mold's identity in May, all the while acknowledging that the conclusive identification record did not exist.

Company Actions and Responses

In light of these discrepancies, the Kousei Club (株式会社薫製倶楽部), based in Okayama, led by Mr. Masaaki Mori, has formally reached out to the Osaka Mayor's office as of July 26, 2028. Their letter requests a detailed written explanation addressing the contradictions by July 31, 2028. If no sufficient response is received by this deadline, the company is considering further actions, including potential administrative reviews and appeals.

This incident raises pressing questions about the diligence exercised by local authorities in ensuring public health and the accuracy of food safety communications. As the timeline continues to unfold, all eyes are on the Osaka City administration to clarify their stance and factual basis concerning this troubling issue.
