This service eliminates the boundary between the real and virtual worlds, allowing users to enjoy everyday experiences such as attending live music performances, enjoying art, having conversations with friends, and shopping―anytime, anywhere.
Furthermore, in collaboration with domestic and international partners, KDDI will provide support in introducing Japanese creators and content to the world. KDDI will build a creator economy in which creators can produce value and be compensated for their work.



KDDI launched Virtual Shibuya, an urban-linked metaverse, in May 2020, and Digital Twin Shibuya, which links real and virtual spaces, in October 2022 as part of its continuous initiatives to expand urban experiences by utilizing 5G communications and AR/MR technologies. For the past three years, Virtual Shibuya has offered a new form of entertainment enabled by technology, such as live music performances from artists, talk shows featuring anime and manga characters, and other urban-linked experiences that are anchored in a virtual space.
αU will evolve from a traditional public space for experience to a space for communication.

αU metaverse

This is a metaverse service that allows users to encounter a variety of communities where they can enjoy live music performances from artists and talk with other users within the cities of Shibuya and Osaka recreated in a virtual space.


  • (1) Voice communication with avatars
    Participants communicate with a voice as the avatar of their choice. Using voice lets them comfortably interact with each other since voice can convey feelings that text cannot capture. Users gather and talk at bars, izakaya taverns, cafes and other communication spaces, which in turn develop into communities. These communities facilitate the birth of new entertainment experiences and creatives.
  • (2) Venue for events and meet & greets that are unique to the metaverse
    This virtual space serves as a venue for new types of live music performances, live talk shows from celebrities, and exhibitions from creators. In the meet & greets that take place after the events, users can communicate directly with the artists and other fans. They can talk with others in close proximity through avatars―something that can only be achieved in the metaverse.
  • (3) Everyone can become a creator
    Users can start creative activities by redecorating their own room (My Room) in a separate location from the city with furniture and other items to express their own uniqueness. In the future, users will be able to hold live talk shows as an extension of fun conversations with other people invited to My Room, as well as to create and sell avatars and furniture for My Room. In the metaverse, everyone is free to become a creator.
