Demand for Clarity on Pubeluric Acid from Osaka City

In light of health concerns regarding products related to red yeast rice from Kobayashi Pharmaceutical Co., Ltd., Kyunsei Club, based in Okayama Prefecture, has been actively pursuing the verification of facts surrounding these issues. This stems from a health incident reported in connection to Kobayashi's products. On March 10, 2026, the company initiated a public disclosure request directed at relevant authorities to unfold the facts concerning these health concerns.

Background of the Information Disclosure Request

On June 7, 2026, Kyunsei Club filed a request for information disclosure aimed at obtaining scientific documentation held by Osaka City, which would confirm the presence of Pubeluric Acid in “Red Yeast Rice Cholesterol Help” and related products. However, the reply received on July 22, 2026, categorized as “Partial Disclosure Decision No. 8202,” revealed a troubling aspect: four out of five disclosed documents were submitted by Kobayashi Pharmaceutical itself to Osaka City, with no scientific documents generated or held by Osaka City included. This raises questions regarding the basis on which these products were mentioned publicly.

Key Facts Identified

A significant point highlighted in this situation is Osaka City’s reference to Pubeluric Acid in a detailed food poisoning report submitted to the Ministry of Health, Labour and Welfare on March 19, 2025. This reference clearly indicates that the city had identified and named the substance, implying that there must have been some basis or evidence supporting this identification. Nonetheless, the partial disclosure decision did not include any proprietary Osaka City documents that would provide the scientific basis for this identification.

Requests Made in the Opinion Statement

In light of the facts presented, Kyunsei Club has articulated specific demands directed at the Mayor of Osaka City, Mr. Hideyuki Yokoyama, through an opinion letter submitted on July 25, 2026:

1. Prompt Disclosure of Basis: The city should expeditiously disclose any independently-held documents that support the reference to the substance Pubeluric Acid made on March 19, 2025.
2. Clarification if No Documents Exist: Should such supporting documents not exist, the city needs to provide a clear explanation of the basis upon which it used the term “Pubeluric Acid” in its reports.
3. Disclosure of All Relevant Scientific Data: If there are other scientific basis documents held independently by Osaka City regarding the matter, those should also be disclosed without further delay.

Summary of Submission

• - Submission Date: July 25, 2026
• - Recipient: Mayor Hideyuki Yokoyama of Osaka City (Department of Health and Life Hygiene)
• - Subject of Decision: Partial Disclosure Decision No. 8202 (Notification dated July 22, 2026)

As a company, Kyunsei Club remains committed to demanding accountability in the administrative processing of this sensitive issue. We pride ourselves on our transparency and dedication to health, and we will continue our efforts until clarity is reached regarding the implications of Pubeluric Acid.
