Value proposition
Industry-lowest cost GPU cloud service (up to 75% cheaper than hyperscalers like AWS) by repurposing idle facilities (closed schools) in regional Japan, using outside-air cooling, and stripping unnecessary enterprise features to deliver pure computing power.
Products and solutions
GPUSOROBAN (GPU cloud service), AI Supercomputer Cloud (B200 clusters), High-Performance Computing, Remote Workstation, PICSOROBAN (browser-based image generation AI), High-power housing service, EdgeHUB
Unique value
Japan's most cost-effective GPU cloud — 1/4 the price of AWS — powered by regionally distributed, repurposed-facility data centers with PUE < 1.1, enabling domestic AI development without reliance on expensive foreign cloud providers.
Target customer
AI/ML startups, enterprise R&D teams, academic research institutions, manufacturing/construction firms, and government agencies needing GPU compute for LLM training, inference, image generation, CAE simulations, and rendering.
Industries served
AI/ML, Manufacturing, Construction, Academia & Research, IT, Gaming, Media
Technology advantage
NVIDIA Elite Partner (first Japanese CSP); NVIDIA "Best CSP Partner of the Year" 2022; METI "Cloud Program" supply security plan certification; Patents on heat-efficient data center design; ISO27001/27017 ISMS certification; P-Mark privacy certification; Proprietary "differentiated roof" cooling architecture; 5 data centers across Ishikawa, Kagawa, Saga prefectures.
How they differentiate
1) Cost leadership: 1/4 the price of AWS by eliminating non-essential features and using repurposed regional facilities; 2) PUE < 1.1 (industry-leading power efficiency via outside-air cooling, no AC); 3) Regional distributed DC network using closed schools for local economic revitalization; 4) First Japanese CSP to achieve NVIDIA Elite Partner status; 5) Japan GPU Alliance co-founder with KDDI and Sakura Internet for mutual GPU resale.
Main competitors
Sakura Internet ("Takaburi" GPU cloud), KDDI (GPU Cloud / WAKONX), AWS, GCP, Azure (hyperscaler GPU instances), Preferred Networks (Chainer/CUDA ecosystem), ABEJA (AI platform with GPU infra)
Key partnerships
