When you go to Kagoshima, Kyushu Shinkansen is the best way to get there. It is fast and the trains come very frequently. But if you have a time, please consider the route from Kumamoto to Kagoshima-Chuo via Hitoyoshi and Yoshimatsu on Hisatsu line (肥薩線). It is very scenic route. JR Kyushu operate very attractive trains on this route.
Udo Jingu shrine (鵜戸神宮) was one of the place where I really loved to go. When I had a trip to Takachiho, I had a time to go there. I use a local bus on the way and get on cruising train Umisachi-Yamasachi on the way back from Udo Jingu shrine.I would like to show you how to access to Udo Jingu shrine by both transportation.
Takachiho is known as the land of Japanese mythology. There are lots of shrines and places that are related to the mythology. And also Takachiho Gorge is one of the “Must-See” spots in southern Kyushu area.
I visited there in mid March, 2012. I would like to share my experience with you. I hope this will be helpful for your trip to Takachino.
