When we talk about trains in Japan, some of us tend to think only of the Shinkansen, the high-speed train. Extremely practical, comfortable, punctual and fast, it's also very expensive. Hence the need to use a Japan Rail Pass.
Riding trains during a trip to Japan is also borrowing a multitude of small lines in the countryside, or commuter trains around major cities, which are no less clean. And most importantly, the experience is often more charming and perfectly quiet to enjoy beautiful landscapes.
