If a seat comes back

Cancellations: on the restaurant's Ikyu page, tick "空席通知メールに登録する" (vacancy-notice email) and Ikyu notifies you — members only, offered by some restaurants, and it does not hold the seat. faq.ikyu.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.
