Disclaimer
Educational estimate, not an official calculator. Budgets can run out without notice; the price at checkout is final.
Rules as of 2026-10-13 from the Japan Tourism Agency (観光庁) and the seven prefecture campaign sites. Not affiliated with any government body, travel agency or booking site.
What this is
A free educational calculator. A dated copy of the Kyushu Fukko Ouenwari 2026 (九州ふっこう応援割) rules published by the Japan Tourism Agency and the seven Kyushu prefectures returns the discount, the price to pay and the per-person cap for a booking, and checks whether the nights and booking date fall inside each prefecture's published sales and stay windows for the chosen channel.
What it is not
It is not an official calculator and it cannot see live budgets. Each prefecture's budget, and each seller's own allocation, can run out without notice; sellers decide which plans carry the discount and how they round it. The discounted price at checkout is what you pay. Rules can change; check the prefecture campaign site or call its call center (Japanese) before you book. Not affiliated with the Japan Tourism Agency, any prefecture, travel agency or booking site.
