Prologue

I walked from Tokyo to Kyoto for 13 days on June, 2016.

At that time, I was not employed, so I had time.

An idea occured to my mind. It's good occasion to do an interesting challenge.

Tokaido road is one of the most important five roads of Edo Era. Two of the five roads connect Osaka and Tokyo and one of them is named Tokaido, the other is Nakasendo. Tokaido runs along the sea side and Nakasendo goes through the mountain sides. Tokaido has 53 post towns.

Nakasendo seemed more difficult, because it has several mountains and peaks. On the contrary, Tokaido has only few mountains and peaks. It looked easier to walk.
Compared to Tokaido, Nakasendo has less big cities. In this journey, I planned to stay at Manga cafes, which are similar to Internet cafes but offer individual rooms. Staying there was good to my wallet. The bigger the cities are, The more Manga cafes there are.
I've travelled from Tokyo to Nagoya by bicycle before. At that time, I biked a portion of Tokaido, so I had some knowledge about it. From my experience, I was confident this journey was possible.
At first, Ohenro(visiting 88 temples in Shikoku by foot) came to my mind. But the total length is about 1,400km, so it would take over a month. It's a bit too much for me.
