As previously notified, the terminology "DLsite Account" will be changed to "viviON ID" on April 21st, 2025 (JST) due to a transfer of management from subsidiary (EISYS, Inc.) to parent company (viviON, Inc.)

This is strictly a terminology change and there are no changes to the nature of the service itself.
Users who are currently using our services can continue to do so without the need to perform any complicated procedures
Please note that the provision of DLsite will continue to be handled by EISYS, Inc.

* What is a "viviON ID"? (Previously "DLsite Account")
viviON ID is an integrated ID service which gives users access to various services provided by viviON Group via a single Login ID.
This ID is currently used to log in to services such as DLsite, Ci-en, DLsite NijiGAME, etc.
We plan to introduce even more services in future.
