Train is most common and useful tarnsporation in Japan. You can go anywhere in Japan by using just trains. The rails will bring you Hokkaido to Kyushu. So if you know how to use train in Japan, then you will never have problem with going anywhere. And there is shinkansen as well. Shinkansen is very expensive but much much faster than trains. You can use shinkansen instead of using airplane. Shinkansen takes longer than airplane but much much convenient. Plus, between Tokyo-Osaka takes around the same time.

Very useful and much faster transportaion. It is also very expensive. It is even more expensive than airplanes. Alought you just need to go train station and you will never have security check and stuff like that. So much much convenient compare to airplane. I highly recomand you to use shinkansen if its not super far. Like Tokyo to Osaka, Kyoto, Hiroshima.
There is IC card in Japan which you can use it for bus, train, taxi, every single transportation in Japan. If you get one, you can use it all over Japan. And IC card looks diff from each area of Japan. Good for your gift from Japan! It will cost 500 yen to make at first but when you leave Japan, you can give your IC card back at train station. If you do, you will get 500 yen back. Just get it!! It will makes your trip in Japan much nicer! Let's enjoy Japan!!!
