How to find it
9F of the ten-storey MT Building, one block east of Chuo-dori on the back street between Akihabara and Suehirocho stations. Take the lift from the ground-floor entrance; a separate girls bar occupies 10F of the same building, so check the floor sign.
Tips
- Opens at 16:00, so it is shut during the day; open year-round, closing at 1:00 the next morning per the official site.
- The charge system and menu are posted only as images and no payment methods are stated, so bring cash to be safe.
- The cast working that day is posted daily on the official Schedule page and on X (@mermaid_bar).
