The distance by road from Shikoku to Tokyo is 800km. I took a ferry because it was slightly too far to go by bicycle.
It's easy when I use the ship because I can carry the bicycle without dismantling it.
As for the fare, it was 10,000 yen per person, 2,800 yen per bicycle, and the travel time was 18 hours.

I waited for the sunrise and started cycling so I arrived at the Tokyo Port before daybreak. I cycled to my house via Ginza, which is the greatest shopping street in Tokyo. Ginza in the early morning was still "sleeping".
