The Japan National Tourism Organization (JNTO) has launched a fantastic new comprehensive golf guide for tourists. This site is the official guide of the Japanese government and is a tremendous guide for golfers coming to Japan.
You can discover some great courses, routes, and activity planners and it ties in with all the other amazing experiences in Japan- which are also part of the larger site.
