No release day — book any time

This house takes overseas bookings only through hotel concierges, or does not accept them, so we can't request it — follow for the alert and book it the way the house asks. We email you before it opens — the day before, on the morning of release day (08:00 JST) and about 30 minutes before when the opening time is known — with the time in your time zone, how this house takes bookings, and a link to the step-by-step page. Free.
