Explore our flagship modular battery containers, liquid-cooled industrial cabinets, and high-voltage off-grid battery packs deployed across Tokyo's high-tech corridors.
Tokyo stands at the nexus of Japan’s ambitious Zero Emission Tokyo Strategy 2050 and the Ministry of Economy, Trade and Industry (METI) Green Transformation (GX) roadmap. As urban density increases and demand for decentralized microgrids, high-frequency trade data centers, and advanced autonomous robotics accelerates, original equipment manufacturers (OEMs) and commercial facilities across Greater Tokyo demand specialized battery solutions.
Standard off-the-shelf battery packs frequently fail to satisfy Tokyo's stringent spatial, thermal, and regulatory constraints. Our rapid prototyping ecosystem bridges this critical gap. Combining over 120 years of collective battery engineering expertise with state-of-the-art multi-chemistry assembly, we empower Tokyo-based engineers to move seamlessly from initial 3D CAD modeling to functional, certified, field-ready battery prototypes within 14 to 21 business days.
From seismic-resilient commercial building basements in Chiyoda to automated logistics hubs surrounding Tokyo Bay, our custom battery packs are architected specifically for Japan's unique operating environments.
Tokyo's core financial sector demands zero-downtime Business Continuity Planning (BCP). We prototype compact, high-discharge (C-rate up to 5C) rack-mounted LiFePO4 battery modules equipped with fast-switching BMS that transition from TEPCO grid utility to battery backup in under 4 milliseconds.
Serving Tokyo’s premier precision machining and robotics manufacturers in Ota Ward, we supply low-profile, shock-resistant 24V and 48V custom lithium battery packs with high cycle stability, supporting fast opportunity charging for 24/7 autonomous warehouse fleets.
In alignment with the Tokyo Metropolitan Government’s earthquake preparedness policies, our 100kWh to 5MWh containerized BESS solutions provide off-grid resilience during natural disasters, incorporating Tokyo Fire Department-approved gas suppression systems.
Heavy-duty, IP67-rated 699kWh to 1MWh liquid-cooled lithium battery containers designed for coastal anti-corrosion performance, enabling heavy harbor cranes, tugboats, and delivery trucks to zero out operational carbon emissions.
Deploying robust 10ft / 20ft containerized solar BESS units to island microgrids administered by Tokyo Metropolitan Government, reducing reliance on costly diesel imports and stabilizing island solar-plus-storage microgrids.
High-reliability smart battery packs compliant with IEC 60601-1 medical device standards. Designed for portable diagnostic equipment used in Tokyo’s world-class university hospitals and specialized research clinics.
Exporting battery systems to Japan or manufacturing locally within Tokyo requires strict adherence to safety certifications and grid interconnection protocols enforced by METI and TEPCO.
