TableCheck has no vacancy alert for future dates; its emails are about your own booking, and a same-day queue exists only where the restaurant turns it on. support-diners.tablecheck.com
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.
