New 'Friend Invitation Feature' arrives on the official Karaoke BanBan app - Coupons presented to both the inviter and the invitee

Karaoke BanBan, operated by Shin Corporation (Headquarters: Minato-ku, Tokyo; President and CEO: Norihiko Kawaguchi), released a new 'Friend Invitation Feature' on the official Karaoke BanBan app on Monday, May 25, 2026. When an app member invites a friend, family member, or colleague who has not yet registered for the Karaoke BanBan app, and that person visits for the first time, coupons are presented to both the inviter and the invitee. The 'Friend Invitation Feature' is an advantageous incentive program where Karaoke BanBan official app members share an invitation code with friends, family, or colleagues who are not yet registered, and discount coupons are granted to both the inviter and the invitee. The flow of invitation establishment is as follows: 1. The inviter shares the invitation code with friends, family, or colleagues. 2. The invitee downloads the Karaoke BanBan official app and registers as a member. 3. The invitee enters the invitation code in the app. 4. The invitee visits a Karaoke BanBan group store for the first time and checks in as the representative. 5. Coupons are granted to both the inviter and the invitee. Coupons can be checked from the coupon screen of the Karaoke BanBan official app. The expiration date is 3 months from the date of grant. Please note that you must visit within 30 days after entering the invitation code. The benefits are a 300 yen OFF coupon for the inviter and a 500 yen OFF coupon for the invitee. To commemorate the release of this feature, we will hold a 'Friend Invitation Campaign' from Friday, June 5, 2026.
