Overnight ferry experience from Hokkaido to mainland Japan

A popular long distance ferry ride from Hokkaido to Mainland of Japan is quite incredible. Ferry ships can carry both passengers and vehicles. Several routes operate from Hokkaido to Mainland of Japan. During sailing, the ferry also serves food and restaurants, convenience store, souvenir shops, Onsen, cinema services. Depends on the ferry, you can choose Japanese style bedroom or western style bedroom according to the pricing. The ticket price from Hokkaido to Niigata costed around 220 USD for one Japanese style room for me. I took a reservation for Yukari overnight ferry from Hokkaido. The ferry shopped around 30 mins at Akita prefecture to ride off the passenger at the early morning. Yukari ferry is serving for 846 people and 18,229 tons of cargo. It can be available to carry the vehicle.
