Introduction

Kumamoto City has taken a significant step toward modernizing its governance and decision-making processes by adopting Snowflake's AI data cloud technology. On April 24, 2026, Snowflake Inc., headquartered in Tokyo, Japan, announced that it has completed its registration under the Government Information System's Security Assessment Program (ISMAP) and is launching its full-scale entry into Japan's public sector. The adoption of Snowflake's technology in Kumamoto City is a groundbreaking initiative that signals a robust commitment to leveraging data for better governance.

Background

In recent years, local governments in Japan have faced numerous challenges, including population decline, an ageing society, and the need for disaster response and infrastructure maintenance. To tackle these issues effectively, there is a growing need for data-driven decision-making, known as Evidence-Based Policy Making (EBPM). Many local governments have vast amounts of dispersed data. This has made cross-departmental analysis and swift decision-making quite difficult. Hence, Kumamoto City identified the need for a unified data utilization platform.

Overview of the Kumamoto Data Utilization Platform

The newly established data utilization platform employs Snowflake’s AI data cloud service, which is recognized for its unique architecture that separates storage from computing. This allows for flexible expansion of processing capabilities according to analytical needs. Previously, Snowflake's services were primarily adopted by private enterprises. However, with ISMAP registration confirming its robustness, Kumamoto City has become the first public entity to implement this technology in Japan, achieving a stable yet scalable data utilization environment.

Features of the Kumamoto Data Utilization Platform

• - First Public Entity to Adopt Snowflake:

Snowflake provides high-speed processing, scalable architectures, and stringent security measures, facilitating the diverse utility of data. Consequently, the speed of data analysis is significantly enhanced.

• - Accessibility for All City Staff:

Every employee within Kumamoto City can log into Snowflake without requiring any special technical skills, allowing them to access the latest data from their desks.

• - Efficient Data Shaping with No-Code Tools:

The integration of the data linkage tool, ASTERIA Warp, automates data collection and processing to Snowflake, greatly reducing the workload for personnel involved in data management.

• - Highly Scalable and Secure Cloud Infrastructure:

Built on AWS, the platform enhances its network security and monitoring systems, ensuring flexible adaptation for future scaling needs.

• - Cross-Organizational Data Sharing through Snowflake:

The integration of various data sets allows for enhanced analysis across departments.

Efforts Toward Operational Improvement

The platform is expected to alleviate the administrative burdens involved in data collection and analysis. By linking with Business Intelligence (BI) tools, it automates aggregation and graphical representation of data, considerably easing the workload associated with traditional report generation.

Incorporation of Open Data and Advanced Utilization

In addition to internal data, the system incorporates open data published by the government’s statistical portal, e-Stat. Snowflake’s high data integration capabilities enable the management of various formats and granularities, facilitating analyses that connect population dynamics and socio-economic indicators to policy impacts. This capability supports a more compelling exploration of policy considerations and assessments of policy effectiveness.

Future Outlook

This initiative is a pioneering example of leveraging data platforms in public sector governance. Kumamoto City aims to further advance its managed governance processes based on data. Looking ahead, officials are considering the use of Snowflake Intelligence, a dialogue-based AI feature that allows staff to access data interactively, enhancing their analytic capabilities even without advanced skills.

Perspective from Snowflake’s Leadership

Ryuji Ukita, the President of Snowflake, expressed, "We are tremendously honored that Kumamoto City is the first local government in Japan to fully adopt Snowflake after our ISMAP registration. The ability to use data effectively in the public sector is crucial for solving regional challenges in Japan. This implementation demonstrates that Snowflake’s robust security, governance, and exceptional data processing capabilities meet strict administrative standards. We look forward to further supporting local governments, especially through our partnership with NTT Data Kyushu, to advance EBPM in Japan."

Through its advanced data and AI platform, Snowflake envisions supporting the promotion of EBPM and the enhanced utilization of data across other municipalities, contributing to the establishment of sustainable local communities.
