Pricing & System

Entry and exit are handled smoothly via the LINE app

Entry and exit at filament are handled entirely through the LINE Mini App. Just open the app and slide — everything from check-in to payment is done. If you don’t use LINE, you can do the same with just an email address. No membership registration is needed.

Check-out

During staffed hours, please tell a staff member when leaving. During unstaffed hours, slide the checkout bar on the screen you used to enter (the LINE Mini App or the email link); the door unlocks automatically after payment. Everyone must leave by 24:00.

Private room reservations

You can check private room availability in the same app and reserve — and pay in advance — on the spot.

If you don't use LINE

First-time visitors are welcome during unstaffed hours. Scan the QR code at the entrance with your smartphone and choose the LINE Mini App or your email address (with email, you enter from the link we send you). No membership registration is needed. If you do not have a smartphone, please visit during staffed hours for in-person assistance.
