When you don't plan, sometimes things can go wrong, I didn't realized that on Saturdays in Japan almost all hotels are fully booked. So we took the shinkansen and went to the south of Japan. The idea was to go to Kumamoto and rent a car there. Book a hotel and drive to Takachiho, it was a good plan. But the navigation was in Japanese, so we went to the hotel and asked for them to put in Takachiho in the navigation system. They did but it was a different Takachiho :(...
