Disaster Information in JMA with Amazon Cloud Service
Japan Meteorological Agency (JMA)
Applied Services: Amazon S3
The Japan Meteorological Agency (JMA), a department of the Ministry of Land, Infrastructure, Transport and Tourism, operates 60 weather stations across Japan. Classmethod designed an AWS architecture enabling extended data storage using Amazon S3 with access controls — supporting long-term disaster data retention, immediate information sharing between weather stations, and local disaster management case studies.
Features of the System
Intuitive Data Backup
Simple, reliable backup across all 60 weather stations
Unrestricted Storage
No capacity ceiling — scale as disaster data accumulates over decades
Multi-Region Replication
Data stored across Tokyo and Singapore regions with automatic multi-zone replication
Enterprise Security
Encrypted communications and administrator account controls for government data
Amazon S3 Durability
Amazon S3 provides 99.999999999% (11 nines) durability — storing data across a minimum of three physical Availability Zones with automatic replication. For JMA's disaster management data, this means effectively zero risk of data loss regardless of localized infrastructure failures.
Results Achieved
- • Disaster information stored durably across Tokyo and Singapore regions
- • Immediate data sharing between all 60 weather stations
- • 99.999999999% durability via S3 multi-zone replication
- • Encrypted communications protecting sensitive government weather data
- • Pay-as-you-go pricing — no upfront storage infrastructure investment
This case study uses Amazon S3.
Classmethod helps government and public sector organizations deploy Amazon S3 for critical data storage — delivering enterprise-grade durability, access controls, and multi-region replication for data that cannot be lost.
