Access by airplane
Although there are flights available to Kumamoto Airport from Haneda and Itami Airports as there aren't many scheduled the best option may be to use the bus service from Fukuoka airport.
From JR Kumamoto Station you can take "Kyushu Odan (Trans-Kyushu) bus" direct to Kurokawa Onsen. This service is to Kurokawa Onsen via Kumamoto airport.
We would also recommend the direct "Fukuoka/Fukuoka Airport—Kurokawa Onsen" Nishitetsu Bus.
From Kagoshima, take the Shinkansen from JR Kagoshima Central Station and from Miyazaki take the Express Nanpu bus (Kyushu Sanko Bus), then disembark at JR Kumamoto Station and take the Kyushu Sanko bus to Kurokawa Onsen.
Reservations may be made using the reservation form or by telephone.
