Aug 11 (Solo Travel Japan) - I tried a brand new overnight ferry in Japan, which is like a capsule hotel.
The Yokosuka - Shinmoji route was newly opened on the 1st of July, 2021. Tokyo Kyushu Ferry operate two ships (Hamayu and Soleil) Mon to Sat.
There are five different types of cabins on the ferry.
Deluxe, State, State with pets, Tourist S and Tourist A.
