Map showing our location

About one hour ride by bus or car from the nearest railway station “Aso”. It would be most recommendable to drive your car or rented car to reach our place. If you use bus, please contact us, ikoi, before visit.

Although Kurokawa Spa is located in Kumamoto, Kyushu, southern part of Japan, it snows often during the winter because of high altitude. Please make sure of snow chains or stud-less (snow) tires to avoid slips.
