MOL Sunflower (Tokyo area ↔ Hokkaido)
The "SUNFLOWER" operated by MOL Sunflower Ltd. is a ferry that allows you to travel between Tokyo and Hokkaido at a very economical price. A new ship which went into service in 2017 (the evening ferry) has luxurious suites and relaxing, Japanese style rooms.
Even though I'm sensitive to the cold, I still had a blast. The scenery was amazing!
