I went to Muroto Cape in Kochi prefecture in Shikoku island, Japan by train and bus half round of island of Shikoku from Osaka by only public transportation, but no bullet train. (I had a discount ticket only use for local trains and buses.)
Here Muroto Cape is one of the beatiful cape in Japan, and there is spa and sea salt factory, and Samurai style house town.
There is a huge Kobo daishi monk statue who used to travel around the country to pray, and he was the monk who started pilgrimage in Shikoku island. There was a cave that he used to pray in there, so somebody built the statue recently next to the cave.
