メタカープ is a smartphone app designed exclusively for members of the Carp Fan Club to participate in a Carp-themed metaverse using Carp Boy and other avatars. It offers a next-generation Carp support experience, allowing users to enjoy watching home games and communicate with fellow fans.

With the app, you can watch live broadcasts of home games on a giant screen within the metaverse. This feature is only available for Carp home games.

The app also provides communication features, allowing users to select from 12 different avatars with different genders, hairstyles, and uniforms. You can enjoy watching games and communicating with others using your preferred avatar. Within the metaverse, you can cheer alongside up to 100 avatars, using unique Carp fan features such as squat cheering, as well as sending stamps and messages.

To join メタカープ, up to 5,000 people can enter the metaverse for each game. Entrance to the metaverse is limited to Carp Fan Club members, who can also invite one person per game, such as a non-member family member or friend, to join メタカープ.
