From Kumamoto, we rented a car for our road trip to first
Mt Aso (too bad we cant go up because of eruption warning),
then Kurokawa Onsen for onsen hopping and visited one of the special onsen – cave onsen.
After that we spent one night at an Onsen Hotel with private onsen in our room. We had a great dinner and breakfast at the hotel.
The next morning we drive to Takachiho Gorge for boat riding before heading back to Kumamoto to return the car. Before we returned the car we stopped by to visit the famous Kumamoto Castle (Top three castle in Japan) that become ruins after 2016 earthquake. The restoration process of the castle still ongoing and we heard it might take as long as 10 years for full restoration.
