ISMAP (Government Information System Security Management and Assessment Program)
Japan's government cloud security program — analogous to FedRAMP. Cloud services used by Japanese government agencies must be ISMAP-authorized. Managed by the Digital Agency and the Information-technology Promotion Agency (IPA).
Who must comply: Cloud service providers selling to Japanese national and local government agencies.
Why it matters: Like FedRAMP, ISMAP is a procurement gate. Authorization is time-consuming and expensive. A compute marketplace provider with ISMAP authorization has exclusive access to the Japanese government market. First-mover advantage is significant — as of 2025, fewer than 100 services are ISMAP-registered.
