Japan has built one of the world’s most sophisticated supermarket refrigeration markets by solving a challenge very different from Europe or North America. Rather than focusing on large hypermarkets or long-distance logistics, Japanese manufacturers have engineered highly efficient refrigeration systems for dense urban supermarkets and more than 55,000 convenience stores. Government incentives, high electricity prices and strict safety regulations have accelerated the adoption of compact transcritical CO₂ (R744) refrigeration, making Japan the global benchmark for small-format natural refrigerant systems. Today, Japanese engineering continues to influence supermarket refrigeration projects worldwide through advanced controls, automation and energy-efficient cooling technologies.

Why Japan Matters
Japan has taken a different route from Europe in its transition to natural refrigerants.
While many European retailers adopted propane (R290) for plug-in refrigeration cabinets, Japan pioneered compact transcritical CO₂ (R744) condensing units designed specifically for convenience stores and small supermarkets. Strict domestic safety regulations surrounding flammable refrigerants, combined with government incentives and high electricity costs, encouraged manufacturers to invest heavily in CO₂ technologies instead.
The result is one of the world’s most mature markets for compact natural refrigerant refrigeration.
1. Panasonic Corporation
Founded: 1918
Headquarters: Kadoma, Osaka
FY Revenue: More than ¥8 trillion
Panasonic is widely regarded as the global pioneer of compact transcritical CO₂ (R744) condensing units for supermarkets and convenience stores.
Its systems have been installed across thousands of Japanese convenience stores and have become an international reference point for urban retail refrigeration. Panasonic’s continued investment in energy efficiency, remote monitoring and low-GWP technologies has helped shape commercial refrigeration standards well beyond Japan.
2. Daikin Industries
Founded: 1924
Headquarters: Osaka
FY Revenue: More than ¥4 trillion
Although best known globally for air conditioning, Daikin has significantly expanded its commercial refrigeration portfolio.
The company supplies integrated supermarket cooling systems, heat pumps and energy-efficient refrigeration technologies that support retailers looking to reduce operating costs while meeting environmental targets.
3. Hoshizaki Corporation
Founded: 1947
Headquarters: Toyoake, Aichi Prefecture
FY Revenue: More than ¥400 billion
Hoshizaki is one of Japan’s leading manufacturers of commercial refrigeration and foodservice equipment.
Its refrigeration systems are widely used in supermarkets, convenience stores and hospitality businesses, where reliability, hygiene and low operating costs remain essential.
4. Mayekawa Manufacturing (MYCOM)
Founded: 1924
Headquarters: Tokyo
FY Revenue: Private
Mayekawa has earned a global reputation for industrial refrigeration and natural refrigerant technologies.
Its expertise spans ammonia, CO₂ and other environmentally friendly refrigerants used throughout food manufacturing, cold storage and logistics operations.
5. Mitsubishi Electric
Founded: 1921
Headquarters: Tokyo
FY Revenue: More than ¥5 trillion
Mitsubishi Electric plays an important role in refrigeration automation, controls and intelligent building management.
Its technologies enable supermarkets to improve equipment performance through predictive maintenance, remote diagnostics and energy optimisation.
6. Sanden Corporation
Founded: 1943
Headquarters: Isesaki, Gunma Prefecture
FY Revenue: Private
Sanden remains an established name in Japan’s commercial refrigeration industry despite undergoing financial restructuring after Hisense became the majority shareholder of Sanden Holdings.
The company continues supplying commercial refrigeration equipment and maintains a presence in Japan’s supermarket and convenience retail sectors.
7. Hitachi Global Life Solutions
Headquarters: Tokyo
FY Revenue: Private
Hitachi Global Life Solutions develops refrigeration technologies that combine cooling performance with intelligent energy management.
Its systems support retailers seeking greater operational efficiency and lower electricity consumption.
8. Carel Japan
Headquarters: Tokyo
FY Revenue: Private
As the Japanese subsidiary of Italy’s Carel Group, Carel Japan supplies advanced refrigeration controls, electronic expansion valves and monitoring systems.
Its technologies are widely used in natural refrigerant installations requiring precise temperature management.
9. BITZER Japan
Headquarters: Tokyo
FY Revenue: Private
BITZER Japan supports the country’s refrigeration sector through compressors designed for commercial and industrial cooling.
Although the company is part of Germany’s BITZER Group, its Japanese operation plays an important role in supplying equipment for supermarket refrigeration projects.
10. Danfoss Japan
Headquarters: Tokyo
FY Revenue: Private
Danfoss Japan provides electronic valves, controllers and energy optimisation technologies used throughout the refrigeration industry.
Its products help retailers improve system performance while reducing maintenance costs and electricity consumption.
Industry Outlook
Japan’s refrigeration market continues to evolve around five major themes.
The first is compact CO₂ leadership. Japan remains the world’s leading developer of small-capacity transcritical CO₂ refrigeration systems for convenience stores and urban supermarkets.
The second is government support. Programmes led by Japan’s Ministry of the Environment have helped retailers replace HFC-based refrigeration with natural refrigerant technologies through financial incentives covering a significant share of installation costs.
The third is automation. Labour shortages and high operating costs are encouraging supermarkets to integrate refrigeration with predictive maintenance, IoT monitoring and remote diagnostics.
The fourth is engineering philosophy. Japanese manufacturers have traditionally prioritised reliability, quiet operation, compact equipment footprints and long service life, making their refrigeration systems particularly well suited to densely populated urban environments.
Finally, the environmental advantages remain clear:
- Traditional refrigerant R404A has a Global Warming Potential (GWP) of approximately 3,900.
- CO₂ (R744) has a GWP of 1.
These environmental benefits continue to drive investment across Japan’s supermarket sector.
What Happens Next?
Japan is expected to remain a global leader in compact commercial refrigeration and intelligent cooling technologies.
The continued rollout of compact CO₂ refrigeration is creating new opportunities across the Japan retail technology sector. For the Japan grocery store industry, advanced refrigeration has become a strategic investment supporting energy efficiency, food safety and operational reliability. Across the wider Japan FMCG sector, investment in digitally connected cold-chain infrastructure is helping retailers reduce emissions while maintaining exceptionally high product quality.
As automation becomes increasingly important, refrigeration systems will play a larger role in connected store management, predictive maintenance and energy optimisation, reinforcing Japan’s position as one of the world’s most influential refrigeration innovation hubs.
