As of March 2023, there were 721 retailers, with PPSs (i.e. Shindenryoku<\/em>) accounting for approximately 17.7 percent of total retail electricity sales,[2]<\/a> illustrating the growing role of competitive suppliers in Japan\u2019s energy landscape. The number of retailers has continued to rise, reaching 780 companies as of August 25, 2025.[3]<\/a><\/p>\n\n\n\n Against this backdrop of market expansion, retail electricity suppliers are required to comply with detailed rules under the Electricity Business Act, its Enforcement Regulations, and the Retail Guidelines. In particular, following the April 2024 amendments to the Act, the obligations to provide explanations to customers and to deliver written documents have been further tightened. Non-compliance can expose suppliers to corrective action or even public disclosure of violations by the Electricity and Gas Market Surveillance Commission.[4]<\/a><\/p>\n\n\n\n Download Full Article (PDF)<\/a><\/span><\/strong><\/p>\n\n\n\n [1]<\/a> This communication is provided as a service to our clients and friends and is for informational purposes only.
