Kyoto Prefecture is one of Japan’s 47 prefectures―government bodies charged with the oversight of the region’s administrative functions. Kyoto Prefecture is composed of six districts and 26 municipalities. Approximately 2.6 million people live in the prefecture.

Since 2009, local municipalities in the prefecture have participated in a cloud computing trial instigated by Japan’s Ministry of Internal Affairs and Communications. The initial goal of the local government initiative was to use cloud computing as the backbone for e-government and to streamline operations by sharing documentation systems. These systems would be housed in a common data center, and municipalities would access them using a governmentwide network.

As part of the trial, Kyoto Prefecture took part in a project to demonstrate data center functions, the interconnectivity between different data centers, and application integration.

The prefecture implemented Oracle GoldenGate, Oracle VM, and Oracle Database with Real Application Clusters to demonstrate how the document-support system could be backed up remotely and restored in real time within a virtual environment. Kyoto Prefecture proved it was possible to restart an operating system and application in 10 minutes in a virtual environment, and that critical business systems supporting document management and decision-making functions could be recovered within two to four hours of a disaster.

Move to E-Governance

A word from Kyoto Prefecture

  • “Using Oracle GoldenGate and Oracle Real Application Clusters, we proved it was possible to remotely back up different operating systems and databases in real time. This ensures our systems can be swiftly restarted in the event of a natural disaster, which is critical if we are to provide emergency services to the public.” – Masato Hirose, Section Manager, Information Policy Division, Department of Policy Planning, Kyoto Prefecture

In 2004, the Policy Planning Division of Kyoto Prefecture created an e-government promotion department. The department developed 14 systems and relevant tools as part of a three-year plan to establish e-government practices. The project also involved extensive business process re-engineering, including staff training.

Almost all 14 systems became operational in 2007, and business reforms yielded concrete results, including greater transparency into procedures, such as tax processing and welfare payments; real-time status updates; and standardization of processes, such as human resources, payroll, and general administration. Gradually, the prefecture moved to a new style of management that enabled better staff development and improvements in the IT infrastructure rebuilding process.

In 2008, Kyoto Prefecture embarked on its next project: adopting a structured approach to data management. At that time, each of the prefecture’s divisions used its own systems, and this was inefficient, expensive to maintain, and prevented data sharing. By integrating systems and managing data in a structured manner, the prefecture hoped to invert conventional practices so that, instead of linking data to services, it would link services and activities to data.

“Managing data in this way enabled us to see a clear flow of services, and we currently run our systems in a structured manner,” said Masato Hirose, section manager, information policy division, department of policy planning, Kyoto Prefecture.

Adoption of Cloud Computing

Backup Efficiency Improved

Full System Recovery in Two to Four Hours




  • Transfer data in different environments, such as Oracle Database on Linux or Oracle Database on Microsoft Windows, to a backup site
  • Minimize the time and cost of backups, while managing the risk to the prefecture if business systems fail
  • Ensure that in the in case of an emergency, business systems immediately fail over to a remote server and full administrative functions are recovered


  • Restarted operating systems and applications in the virtual environment in 10 minutes
  • Recovered critical business systems within two to four hours, even in the event of a large-scale natural disaster, such as an earthquake or tsunami
  • Improved backup efficiency by enabling data to be replicated in different environments, and by backing up heterogeneous environments in an integrated manner in real time
  • Ensured citizens’ services can be quickly resumed in the event of a disaster, using the flexible virtualized system to migrate and restart the database and systems in a safe location
  • Enabled data to be backed up to a remote site in real time, ensuring critical information is not lost in the event of an earthquake or a fire
  • Allowed extra servers to be provisioned on demand, as Oracle VM enables three virtual machines to be run on one physical server
  • Kept operating costs to a minimum while still managing risk, as the virtual backup infrastructure requires only a small initial investment and can be quickly scaled up

Why Oracle

Kyoto Prefecture was attracted to Oracle GoldenGate because the software enabled data to be replicated in different environments, enabling the prefecture to back up heterogeneous environments in an integrated manner. In addition, Oracle was a proven solution, with the vendor providing many cases in which Oracle VM and Oracle Real Application Clusters had delivered tangible results for customers.

“We believed Oracle could provide us with a one-stop service,” said Kawaguchi.

Implementation Process

Kyoto Prefecture undertook the data center synchronization experiment in October 2010, after spending some months building the required infrastructure, implementing the Oracle technology, and completing the network connections between the Kyoto and Hokkaido data centers.

Advice from Kyoto Prefecture
•    Ensure your IT team is knowledgeable about your implementation project, is fully trained at all levels, remains committed to completing the project, and works to resolve any problems, even if they fall outside the original project scope.
