Yes. NVIDIA RTX 5090 capacity is confirmed available in Japan through multiple domestic providers: GDEP Solutions lists RTX 5090 alongside H200 and RTX PRO 6000, and holds accreditation from Japan's MEXT under a research-support partnership programme. CAT Network and Applied Technology also rent RTX 5090 directly. The RTX 5090 is a consumer/workstation Blackwell card, not a rack-scale datacenter part: 32GB GDDR7 memory, 1.79TB/s bandwidth, 575W TDP. For rack-scale training, H100 and B200 in Japan remain the better fit.
