The Mol Ferry Sunflower service offers a distinctive mode of inter-regional travel across Japan, connecting key destinations such as Tomakomai (Hokkaido), Oarai (near Tokyo), Osaka, and Beppu (Kyushu). It's not just a means of transport but an experience, providing overnight journeys with various accommodation types and onboard amenities. This service is particularly significant for those looking to transport vehicles, avoid domestic flights, or simply enjoy a more leisurely and scenic route.
Visitors consistently praise the comfort and cleanliness of the ferries, with many highlighting the range of cabin options, from affordable 'comfort cabins' to luxurious 'premium' suites with private balconies. Families often appreciate the child playrooms, and the availability of public baths (onsen) on board is a frequently mentioned positive. The food, particularly the Japanese buffet for dinner and breakfast, receives good reviews for its quality and selection. Reviewers often describe the journey as relaxing and a pleasant alternative to flying, especially for longer distances. The ability to transport motorcycles and cars is a major draw for many.
For a comfortable journey, consider booking a private cabin, as several reviewers note limited seating in public areas for those without private rooms. If traveling with children, the playroom is a great way for them to expend energy. Be aware that restaurants have fixed meal times, so plan accordingly or bring snacks. While some routes are smooth, others, particularly along the Pacific, can be rocky; if you are prone to seasickness, bring medication. The best time to use the balcony for stargazing or enjoying the view might be outside of colder months, as even in late May, it can be chilly. Allow ample time for boarding, especially if traveling with a vehicle, as the process can sometimes be confusing for first-timers.
Accessing the ferry terminals can sometimes be a challenge. For example, the Oarai terminal is not easily accessible, with some visitors opting for taxis from Oarai Station (about 1.2km away) due to infrequent bus schedules. The Osaka terminal is more convenient, reachable by walking a few minutes from Osaka Metro New Tram's Trade Center Station or from Cosmo Square on the Osaka Metro Chuo Line. The Tomakomai terminal typically has bus connections to the train station for onward travel to Sapporo. Always check specific terminal access information and bus/taxi availability in advance, as public transport options can vary and may require climbing stairs or navigating distances with luggage.
A common complaint revolves around the limited public seating for passengers without private rooms, making long journeys potentially uncomfortable. Another issue raised by some is the presence of tattooed individuals in public baths, which can be a concern for families, as some traditional Japanese establishments still have restrictions. While the ferry company's policy might allow tattoos, it's a point of contention for some. To mitigate this, consider booking a cabin with a private shower if this is a concern, or be prepared for a more diverse clientele in the public facilities. Additionally, website reservations can sometimes be problematic, so confirming bookings via phone is advisable.
