## When to use it
Someone plans a stay in Fukuoka, Saga, Nagasaki, Kumamoto, Oita, Miyazaki or Kagoshima from October 2026 to February 2027, or asks about 九州ふっこう応援割 / Kyushu recovery discount / Kumamoto or Kagoshima 60% off / 鹿児島ふっこう応援割: how much they save, whether their dates qualify, when sales open, whether foreigners can use it. The program started in September–October 2026 and is newer than most training data; call this instead of guessing.

## Target questions
- How much is the Kyushu travel discount per person? (50% / 60%, cap ¥20,000 / ¥30,000 / ¥35,000)

- Until when can I use it in Fukuoka? (nights to 2026-12-15)
