Raiten Booking

Raiten turns your opening hours into bookable slots and sells them through your normal checkout, so bookings arrive as ordinary orders. No separate payment flow, no separate order list. Everything customers read is in Japanese. You can rewrite the calendar and the reminder email from the admin. No theme code needed. Capacity is held per slot, so a slot never takes more than you set. Customers change or cancel from their own link, and bookings appear in a daily list you can export to CSV.
