Microsoft lists two public Azure regions in Japan: Japan East, in Tokyo and Saitama, and Japan West, in Osaka. Microsoft pairs the regions with each other and lists three availability zones for each. That does not mean every Azure service is available in both regions—or supports zones there—so check the service-specific coverage before choosing a deployment location.
What are the Azure regions in Japan?
Microsoft’s current List of Azure regions names Japan East and Japan West as public regions in Japan. Its table gives Japan East’s physical location as Tokyo and Saitama, and Japan West’s as Osaka.
| Azure region | Physical location listed by Microsoft | Paired region | Availability zones listed |
|---|---|---|---|
| Japan East | Tokyo and Saitama | Japan West | 3 |
| Japan West | Osaka | Japan East | 3 |
These are the locations and zone counts in Microsoft’s current region table; they do not establish a region’s original launch date or the service coverage available within it. For broader context on Azure geographies and regions, see Microsoft’s Choose the Right Azure Region for You.
Does “now available” mean the regions just launched?
No launch date for the two underlying Japanese regions is established by Microsoft’s current region list. The dated announcement relevant to Japan West is narrower: Microsoft said Azure Availability Zones launched there in April 2025. That is a zone launch, not evidence that Japan West itself first became available in April 2025. Microsoft described the zone launch in its Asia infrastructure announcement.

What is the difference between Japan East and Japan West?
Location and user proximity
The listed physical locations differ: Japan East covers Tokyo and Saitama, while Japan West is in Osaka. For an application serving users in Japan, evaluate latency from the locations where users and dependent systems actually operate; the region names alone do not establish workload-specific performance.
Pairing and resilience planning
Microsoft lists each as the other’s paired region. That pairing is relevant when designing a multi-region architecture or disaster-recovery plan, but it does not by itself deploy, replicate, or fail over an application. Confirm that each required service supports the intended architecture and determine how data replication, recovery objectives, and failover will work for that service.
Rank #2
- Universal Plug Compatibility: Type A (US / Canada / Japan / China), Type C (EU), Type G (UK / Singapore), and Type I (Australia).

- What You Get: 1× Anker Nano Travel Adapter (5-in-1, 20W), welcome guide, 18-month warranty, and our friendly customer service.
Availability zones
Microsoft’s region table lists three availability zones in each Japanese region. Zones can help with designs that need separation within a region, but zone support varies by service. Microsoft’s Azure Availability Zones overview warns that some services may not support zones in every region that has them. Check the service’s own documentation rather than assuming the region-level count applies to your deployment.
Which Azure services are available in Japan East or Japan West?
Region presence is not a guarantee of service presence. Microsoft publishes regional coverage by service, and availability can differ between Japan East and Japan West. For example, Microsoft’s Azure DocumentDB regional availability page lists both Japanese regions. That example does not establish availability for other Azure products.

Coverage can also include service-specific qualifications beyond whether a region is listed. Microsoft’s Anomaly Detector regions page lists both Japan regions and states that this service does not store or process customer data outside the region where its instance is deployed. That is a statement about Anomaly Detector, not a general guarantee about all Azure services or every data flow.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How to choose a Japanese Azure region
- Check coverage for every required service. Open each service’s regional availability page and verify the exact region, required features, and any limits that affect your design.
- Check zone support separately. If your architecture depends on availability zones, confirm that the specific service and deployment option support zones in the chosen region.
- Evaluate user geography and application latency. Test or model the paths that matter to your workload; Microsoft’s region locations do not provide a latency result for your application.
- Plan cross-region recovery explicitly. If using the paired region for resilience, verify service compatibility, replication behavior, failover steps, and recovery requirements rather than relying on pairing alone.
- Review data residency and compliance requirements for the workload. Confirm the applicable rules and the service’s documented data handling. A region’s location or one service’s processing statement is not a legal-compliance conclusion.
Microsoft’s region table verifies the two locations, their pairing, and the listed zone counts. It does not establish workload-specific latency, pricing, or whether a particular deployment meets a legal or compliance requirement; assess those separately for your application and service.
