Toyama is one of major cities in Hokuriku region. This city is known as the base of Tateyama Kurobe Alpine Route and Kurobe Gorge (Kurobe Keikoku). You also can access to Tateyama by both train and bus, and Shirakawago and Shin-Hotaka by bus directly. This station is the hub of this region.
Matsumoto is the second biggest city in Nagano prefecture. But the station is not a huge terminal station, like Tokyo. But Matsumoto is the junction of many destinations by trains and buses. If you travel this area, you may have to change the trains and the buses at Matsumoto.
Takayama is one of the most popular destinations for overseas travelers. Especially spring and fall seasons are very popular since the festivals are held. This city is also known as the gateway to UNESCO World Heritage Site, Shirakawago. I would like to tell you about the access to Takayama in this post.
