Overview of the Red Yeast Rice Incident

In March 2024, a significant health issue emerged involving red yeast rice products linked to claims about a substance known as Puberulu acid. This incident drew the attention of the Ministry of Health, Labor and Welfare (MHLW), National Institute of Health Sciences (NIHS), and the city of Osaka, leading to multiple announcements suggesting a concerning connection to health damages attributed to this compound. The company Kunsei Club, based in Hayashima Town, Okayama Prefecture, has undertaken a thorough investigation following these claims, looking for corroborating evidence from the stated administrative bodies.

Initial Government Announcements

On March 29, 2024, the MHLW announced that the health issues related to red yeast rice were likely due to an 'unknown component,' postulating that it could be Puberulu acid derived from blue mold. In September of the same year, the MHLW and NIHS released analysis results asserting they had detected and identified Puberulu acid in both raw and processed red yeast products. Animal testing reportedly demonstrated that this substance could lead to renal impairment. The narrative shaped around Puberulu acid became accepted fact, not only in official government statements but also in media reports.

Findings from Information Disclosure Requests

In response to information disclosure requests made by Kunsei Club between the years 2024 to 2025, each of the government agencies provided concerning responses:
1. MHLW claimed no original analytical data was created or retained regarding the identification of Puberulu acid, as well as no documents indicating that it had determined the existence of the substance before March 28.
2. They also stated they didn’t possess any records evaluating the toxicity of Puberulu acid or its classification.
3. The NIHS denied any involvement or creation of related documents, asserting such materials were non-existent.
4. Osaka City revealed that four of the five disclosed documents were submissions from Kobayashi Pharmaceutical and found no evidence of independent identification of Puberulu acid in documents they possessed.

This showed a troubling reality: no substantial or legally recognized documents corroborating the identification of Puberulu acid existed across any of the governmental bodies involved in the health claims.

Distinction Between Claims and Evidence

A critical point to understand from this disclosure is the difference between an official announcement and the physical documentation that should support such claims. Although the MHLW and Osaka City publicly stated that Puberulu acid was a likely cause, the lack of associated substantiating documents presents a significant gap in legitimacy. We need to differentiate between the act of announcing a conclusion and the existence of the evidence that would validate that conclusion.

Clarity on What’s Known and What Remains Unknown

This investigation has revealed that while the government did announce that Puberulu acid was implicated as a health risk, the necessary administrative documentation to support that assertion remains unverified and inaccessible. This finding does not necessarily conclude that Puberulu acid was not present in the red yeast rice or unrelated to health impacts, but places doubt on the validity of the governmental actions based on their statements, including withdrawal orders or public exposé of companies involved.

The 2024 Annual Report from the NIHS notes provisional identification of Puberulu acid based on initial preliminary assessments, yet the lack of follow-up documentation to firmly establish this claim raises critical questions.

The Company's Position

Kunsei Club emphasizes that this incident is not limited to Kobayashi Pharmaceutical; it poses a serious challenge to the entire industry engaged in functional foods, specifically products made with red yeast rice. The lack of evidentiary support confirming the administrative announcements substantially undermines the validity of the government’s actions throughout this case.

The issue raised is not about the existence of Puberulu acid itself, but rather the absence of proper documentation to justify the grave actions taken by the government against entities in the industry, such as recalls and public naming of companies.

In light of the circumstances surrounding this incident, Kunsei Club strongly insists on a comprehensive and scientifically sound elucidation of this matter, as we are dedicated to producing food products containing red yeast rice.
