Controversy Surrounds Kobayashi Pharmaceutical Amidst Red Yeast Rice Lawsuit

The Ongoing Controversy Surrounding Kobayashi Pharmaceutical



In a striking turn of events, the Ministry of Health, Labour and Welfare of Japan finds itself under scrutiny for its role in a recent scandal concerning animal testing related to red yeast rice. This followed the public's discovery that Kobayashi Pharmaceutical Co., a key player in this saga, was both the commission agent and the party responsible for the animal experiments.

The principal question arises: Why was Kobayashi Pharmaceutical, directly involved in the issues at hand, entrusted with conducting these vital tests? Moreover, there are pressing concerns over why the results of these tests were seemingly prioritized in the Ministry's official evaluations and why the public was not adequately informed of Kobayashi's involvement as the principal tester.

Recent Developments


On September 18, 2024, the Ministry disclosed the findings of an investigation conducted by the National Institute of Health Sciences (NIHS), confirming kidney-related injuries associated with the compound known as N-(2-Hydroxyethyl)acetamide (PUVA). Through a public records request, relevant information came to light within the final report titled, “BK1, BK2 and PA: A 7-Day Repeated Oral Toxicity Study in Rats Final Report.”

Key details found within this report include:
  • - The animal tests involving PUVA were conducted between March 29 and June 25, 2024.
  • - It explicitly notes that Kobayashi Pharmaceutical Co. was the commission agent for these tests.
  • - The names of the institutions and contractors conducting the tests remain redacted, raising eyebrows regarding transparency.

Legal Action


In light of these revelations, a legal action has been initiated against the government of Japan, with the lawsuit filed in Okayama District Court. The complaint seeks to overturn the non-disclosure orders related to the identity of the test contractors and facilities involved in these experiments. The lawsuit is officially registered as case number Reiwa 8 (Gyō W) No. 16. The first oral argument for this case has been set for October 6, 2024, at 11:00 AM in courtroom 202 of the Okayama District Court.

This lawsuit could potentially illuminate deeper issues regarding regulatory practices and accountability in Japan's pharmaceutical sector, particularly concerning how public health policies are formulated and the extent of corporate influence in related research.
