Should I buy 7 days JR pass

Hi there!

Lets check your JR ticket costs. You'll need to spend over ¥28,300 on JR tickets in order to make a 7 day JR Pass cost effective:

1. Hakata > Kumamoto: ¥4,990 (35mins, 118km)
2. Kumamoto > Aso(kumamoto): ¥1,080 (99mins, 49km)
3. Aso(kumamoto) > Kagoshima: ¥8,910 (152mins, 223km)
4. Kagoshima > Miyazaki: ¥2,420 (160mins, 122km)
5. Miyazaki > Tokyo: ¥31,590 (589mins, 1589km)

JR ticket cost: ¥48,990 for 5 legs

• 7 day Japan Rail Pass (¥28,300) saving: ¥20,690

For Kurokawa onsen you should aim for Aso station, and then use the bus from Aso to Kurokawa. On arrival at Aso station turn right for the bus ticket office or left for the tourist information desk for further information. Please note the times taken for this travel - although you will make savings if you do this all via JR it will take time (Miyazaki in particular wil take time to get to).

Hope this helps!
