Welcome to B with U

From BMSG came the greatest fan platform, B with U.
With the spread of the Internet and social media, I think it's clear everywhere that the relationship between artists and fans is truly big and important.

On the other hand, sometimes it is precisely because something is important that it becomes a problem.
B with U will help us build the ideal relationship we envision for the year 2024 and for society going forward.
Please make your support visible and feel closer to your favorite artists.

B with U can be enjoyed within the app, on the web, and from all over the world. We will continue to add many new features as needed. Please look forward to it. Also, if you are already using BMSG SHOP or B-Town, you do not need to create a new account. You can go back and forth between all of them with one account.

Let's create an ideal space together where you can fully appreciate the artists' human charm and send them your love and support.
Welcome to B with U.
