MUJI retail chain operator Ryohin Keikaku plans to establish MUJI ENERGY, an 80:20 renewable development joint venture with JERA, in September 2025, the companies announced on June 25, 2025.
According to the companies’ statement, the JV aims to develop 13MW of solar within one year, enough to cover approximately 20% of Ryohin Keikaku’s annual power consumption. The household and consumer goods retailer expects to invest 2.1 billion yen in the new vehicle over the same timeframe, a separate filing shows.
The move follows discussions the companies formally launched in January 2025.
JERA Cross will aggregate output from MUJI ENERGY-owned power plants and sell the associated non-fossil certificates (NFCs) to Ryohin Keikaku under a virtual PPA. The decarbonization-focused JERA subsidiary will sell the generated power into the wholesale market while the retail chain operator will continue to procure power from a separate retailer.
Ryohin Keikaku plans to use the purchased NFCs to decarbonize its tenant stores, where it has less control over power supply than at free-standing shops, and make progress toward its target of covering all of its consumption with renewable generation by 2030.
The company also aims to equip all of its free-standing outlets with on-site solar power plants by 2030. It began installations in August 2023 and, as of January 2025, rolled them out at 25 stores. Separately, it added a 1.4MW rooftop solar system at its logistics center in Hatoyama Town, Saitama Prefecture.
MUJI ENERGY’s planned launch highlights commercial and industrial power consumers’ increasing equity involvement in their power supply chains. Among other such initiatives, it follows Seven & i Energy Management, a power retailer established by Seven & i Holdings in August 2024 and Yamato Transport’s wholly-owned subsidiary Yamato Energy Management founded in January 2025.
