Japan cloud computing providers focus on 'data sovereignty'

Cloud computing providers in Japan are responding to customer demands for better security by offering what's known as "data sovereignty" services.

Data sovereignty refers to safeguarding information by keeping it within a country's borders and subject to local laws and regulations.
The European Union and a number of other countries are adopting such procedures to improve data security.

Fujitsu has teamed up with US IT giant Oracle to start a cloud computing service in fiscal 2025 that will keep data transfer and storage within Japan.

Officials say the agreement ensures use of Fujitsu's local data centers and no information will move offshore.

In a related development, NEC and NTT offer a service to Japanese companies that use generative AI. It processes data through in-house servers, without using data centers.

The providers say the service has limits in processing capacity, but meets the security needs of businesses for the internal storage and transmission of data.
