Aki is an independent, free, alerts-only tool that watches Rakuten Travel for cancellations at highly-rated, sold-out hotels around Japan's biggest events — fireworks shows, festivals, concerts, and marathons — and notifies you the instant a room reopens. It is not an official Rakuten service and does not sell or hold reservations. Availability and booking links come via the Rakuten Travel API and Rakuten Affiliate, and the project is funded by affiliate commissions.
Aki is independent and unofficial — not affiliated with, endorsed by, or sponsored by Rakuten Group, Inc. or any festival organizer. All names, logos, and trademarks belong to their owners. Every booking, payment, change, and cancellation happens on Rakuten Travel under Rakuten's and each hotel's terms.
Aki is free to use. Booking links are Rakuten Affiliate links, and we may earn a commission when a booking completes through one. Those commissions fund this free service; they never add any cost to you.
Availability, prices, and review scores come through the Rakuten Travel API (Supported by Rakuten Web Service). Data can be delayed, cached, or inaccurate, and a room shown here may already be booked by the time you click. Always confirm the final price, room, and conditions on Rakuten before you book.
No account is required. If you enable background alerts, an anonymous Web Push subscription is created and stored only to deliver vacancy alerts. See the Privacy Policy for details; you can turn alerts off at any time.
Aki is an unofficial tool provided by an independent operator, separate from Rakuten Group. The operator's details and contact are listed in the Privacy Policy.

No — it's free. The project is funded by affiliate commissions, at no cost to you.
