Traveling in Japan. Trains and the Ferry.
A majority of travel in Japan is by rail be it JR,subway,Shinkansen or other rail operators. If you are traveling to Japan, purchase a Japanese rail pass it will save you thousands of dollars or whatever currency you are using. One must purchase before departure to Japan at a travel agency. I recommend H.I.C Travel agency. I also took the ferry from Amakusa to Nagasaki. Japanese transportation is very, very reliable and professional. To quality for sure!
