- If a seat comes back
This house takes bookings only by phone, so there is no online vacancy alert.
We still send you release-date alerts: for a set release date, the day before, on the morning of release day (08:00 JST) and about 30 minutes before when the time is known; for houses that open a little every day, a weekly summary.
