Aug 31 (Solo Travel Japan) - I tried a Japanese style cabin with tatami mats on the ferry from Osaka to Shinmoji. Tatami mats are made from Igusa (rush). It will be a unique experience.
The fare was 17,100 JPY / 156 USD for one person
Deluxe Japanese Style Cabin is designed for two or three people. It's required to pay extra fee to use it alone. Above fare includes the extra fee.
Two people: 22,800 JPY / 207 USD
Three people: 34,200 JPY / 311 USD
