◆ THE SHORT ANSWER

Yes. You can rent B300 GPUs in Japan now through vetted partners, contracted directly with the operator running your nodes. On B300 price per hour, the median on-demand rate was $7.50 across 11 tracked providers as of 11 September 2026, with the market spanning $6.50 to $15.00 and hyperscaler rates reaching $17.80. Fujitsu began manufacturing "Made in Japan" sovereign AI servers featuring NVIDIA HGX B300 GPUs at its Kasashima plant from March 2026, a domestic production response to geopolitical supply concerns, though B300 capacity currently runs through specialist providers rather than a confirmed deep hyperscaler regional launch. The revised APPI applies extraterritorially and Article 24 governs provision to foreign recipients, so in-country placement removes the consent step for Japanese residents' personal information. For deeper, more established inventory, H100 and H200 in Japan remain the safer default today; for the same memory ceiling at a lower power draw, see B200 in Japan.

◆ PRICING

What B300 costs in Japan

B300 price per hour here is the tracked market rate. Hokkaido siting saves more in absolute terms at B300's draw than it did for earlier generations, worth asking about even with the added latency.

Market reference ranges as of 11 September 2026, quoted in USD, not Japan-specific quotes. Fujitsu's domestic manufacturing confirms real B300 supply, though thinner than H100 or H200.

Where B300 capacity earns its keep

The workloads Japan's B300 supply is built for.

Fujitsu began manufacturing "Made in Japan" sovereign AI servers featuring NVIDIA HGX B300 GPUs at its Kasashima plant from March 2026, a deliberate response to geopolitical supply chain concerns rather than a routine hardware refresh. The revised APPI applies extraterritorially and Article 24 governs provision to foreign recipients, so in-country placement removes the consent step for Japanese residents' personal information. For Japan-based buyers, B300 access exists today but through a genuinely different supply story than H100 or H200's deep, established Tokyo footprint.

/01

Frontier reasoning at scale

Train frontier-scale models that need the full 288GB memory ceiling, where B300's 15 PFLOPS of dense FP4 compute and higher memory bandwidth reduce the GPU count needed for a given run.

HGX B300 · 288GB · NVFP4

/02

70B+ inference, no sharding

Serve 70B and larger models without sharding across GPUs, since B300's memory headroom avoids the communication overhead that erodes throughput on split deployments.

/03

Long-context without offload

Run long-context inference and reasoning chains without offloading KV cache to slower memory, holding more context in-GPU than any prior generation.

High-density agentic serving

Serve high-concurrency agentic workloads where token throughput per GPU, not just raw FLOPS, decides your cost per request.

◆ FAQ

Frequently Asked Questions

Can I rent B300 GPU cloud capacity in Japan?

Yes, through vetted specialist providers with Japanese placement, contracted directly with the operator. Fujitsu is manufacturing sovereign AI servers with HGX B300 GPUs domestically from March 2026. Tell us your requirement and we will confirm availability within 24 hours.

How much does B300 cost per hour in Japan?

The B300 price per hour globally had a median on-demand rate of $7.50 across 11 tracked providers as of 11 September 2026, with the market spanning $6.50 to $15.00 and hyperscaler rates reaching $17.80. Wholesale rates through GPUaaS.com are quoted per enquiry and vary by commitment term, configuration and placement.

What makes Japanese B300 supply different from other markets?

Domestic manufacturing. Fujitsu is producing "Made in Japan" sovereign AI servers with NVIDIA HGX B300 GPUs at its Kasashima plant from March 2026, a response to geopolitical supply concerns rather than a hyperscaler regional launch.

Why does Fujitsu's domestic manufacturing matter for B300?

It signals a deliberate sovereignty strategy: producing AI servers domestically rather than relying solely on imported hardware, which matters for buyers with supply chain or national security sensitivities.

Does Japanese data protection law affect B300 deployment?

The revised APPI applies extraterritorially and Article 24 governs provision to foreign recipients, so in-country placement removes the consent step for Japanese residents' personal information.

Which workloads suit B300 in Japan specifically?

Frontier-scale training and high-concurrency reasoning inference needing the 288GB memory ceiling, particularly workloads where Japanese data residency or supply chain sovereignty is a specific requirement.
