Regulatory Guidance on Procurement Issues at Hamaoka Nuclear Plant

On April 7, 2026, Japan’s Ministry of Economy, Trade and Industry (METI) issued guidance to Chubu Electric Power Co., Inc. regarding improper procurement procedures for safety improvement measures at the Hamaoka Nuclear Power Plant. This development underscores the importance of compliance with procurement regulations and safety standards in Japan’s energy sector.

Background & Context

The Hamaoka Nuclear Power Plant, located in Shizuoka Prefecture, has been under scrutiny due to safety concerns and regulatory compliance issues. The Japanese government has implemented various laws to ensure the safety and reliability of nuclear energy, including the Nuclear Reactor Regulation Law (Genshiryoku Kisei-hou) and the Act on the Regulation of Nuclear Source Material, Nuclear Fuel Material and Nuclear Reactors (Genshiryoku Shigen Shihou-hou). Following the Fukushima disaster in 2011, Japan’s nuclear regulatory framework was significantly tightened, leading to increased oversight by the Nuclear Regulation Authority (NRA, Genshiryoku Shingi-in). Recent guidance from METI aims to reinforce compliance in procurement processes, particularly in the context of safety improvements at nuclear facilities.

1. Foreign Residents Already Operating a Business in Japan
For those involved in the energy sector or related industries, it is essential to review procurement practices to ensure compliance with METI’s guidelines. This may involve conducting internal audits and revising contracts with suppliers. Failure to comply could result in penalties or reputational damage. It is advisable to consult with legal experts specializing in corporate law to navigate these regulations effectively.

2. Foreign Nationals Planning to Establish a New Company
Entrepreneurs looking to enter the Japanese energy market should be aware of the stringent procurement regulations and safety standards. It is crucial to develop a comprehensive business plan that includes compliance strategies for procurement processes. Engaging with local legal counsel can help in understanding the regulatory landscape and ensuring that all necessary permits and licenses are obtained.

3. Foreign Investors Who Are NOT Residents of Japan
Investors considering investments in Japanese energy companies should conduct thorough due diligence on the companies’ compliance with procurement regulations. Understanding the regulatory environment can mitigate risks associated with investment. Investors should also monitor ongoing regulatory changes and consider engaging local partners who are familiar with the Japanese market and regulatory framework. Inaction could lead to financial losses or missed opportunities in a rapidly evolving market.
