SAKIGAKE管理人 In September 2025, SAKIGAKE JAPAN, in collaboration with Cold Storage Japan and Personal Business Corporation, was selected for the “Global South GX Promotion Project” sponsored by the Tokyo Metropolitan Government.
▶️ Read the official press release:
This joint initiative aims to tackle challenges in food and agricultural logistics in Indonesia by leveraging a Japan-developed, off-grid cold storage technology. It’s a practical project that simultaneously addresses greenhouse gas (GHG) reduction and food waste, representing a new model of Green Transformation (GX) and disaster resilience.
“The Risk of Not Being Able to Keep Things Cold” in Indonesia
In many agricultural and coastal regions of Indonesia, reliable cold storage infrastructure is lacking. About 70% of cold storage units depend on diesel generators, resulting in frequent power outages, soaring fuel costs, and disruptions in food safety, quality, and income. These infrastructure gaps cause a 20–40% spoilage rate in harvested crops and seafood—amounting to an annual economic loss of approximately ¥1 trillion and significant GHG emissions from wasted food.
A Japanese Innovation Transforming the Way We “Keep Cool”
To address these issues, our team is deploying off-grid, solar-powered cold storage units featuring:
- No external power required (solar + battery system)
- High-efficiency insulation and cooling using patented technology (Patent No. 7357401)
- Stable internal temperatures within ±1°C, even in harsh climates (35–40°C)
- IoT-enabled remote monitoring and optimization
- Targets of over 90% energy self-sufficiency and 98% uptime
With this system, we aim to achieve an annual CO₂ reduction of 75 tons and a 20–30% reduction in food loss.

MOBILE COLD STORAGE BOX 2.2M Off-Grid Model
A Circular Model for GX × Disaster Resilience
Each of the three companies brings its strengths to the table to deliver sustainable impact on-site:
- SAKIGAKE JAPAN: Driving implementation-focused GX and disaster resilience projects, including policy design and capacity building
- Cold Storage Japan: Providing next-generation cold chain technology
- Personal Business: Enabling real-time monitoring and data-driven evaluation through IoT and AI
By listening to the needs of local communities and optimizing solutions accordingly, we aim to build a resilient, adaptable, and sustainable model.
From Indonesia to Tokyo: Envisioning Reverse Technology Transfer
This project is not limited to Indonesia—it’s also designed with Tokyo in mind. We are exploring reverse application of the solutions to strengthen Japan’s disaster preparedness:
- Deploying emergency cold storage units at disaster hubs in Tokyo
- Implementing off-grid cold chains for remote islands
- Reducing food waste at central wholesale markets
Through this “technology round-trip” model, we aim to establish a circular GX framework that connects Tokyo and the Global South.
A Collaborative Path Toward the Future
This initiative follows a three-year plan:
- Year 1: Local research and planning
- Year 2: Pilot implementation at three sites in Indonesia
- Year 3: Commercialization and regional expansion across ASEAN
Our goal is to scale up to 1,500 sites, ultimately cutting 37,500 tons of CO₂ per year and standardizing this sustainable cold chain infrastructure across the food sector.
In Closing: GX Begins with Real-World Action
GX—or Green Transformation—may sound abstract, but for us, it starts with listening, showing up, and working alongside communities to build tangible solutions.
- Protecting food security
- Reducing environmental impact
- Strengthening resilience against disaster
We believe these are not just buzzwords, but real, practical goals that require innovation, systems, and collaboration. Through this project, we hope to embody a GX that’s grounded, hands-on, and future-focused.
Thank you for your continued interest and support for SAKIGAKE JAPAN’s mission.
