The Marine Gate Hachinohe Ferry Terminal serves as a crucial link between Honshu and Hokkaido, primarily for the Silver Princess ferry route to Tomakomai. This journey is a significant part of many travel itineraries, especially for those exploring the Tohoku region and Hokkaido. Travelers often highlight the convenience of the terminal's amenities, particularly the onboard souvenir shop which offers a more affordable selection of snacks and drinks compared to what's available on the ferry itself.

For those considering the trip, booking a private room is frequently recommended. While it incurs an additional cost, reviewers emphasize that it significantly enhances the travel experience by providing a comfortable and private space for the duration of the voyage. Arriving with sufficient time before departure, even with a vehicle, is also advised, as the friendly staff are known to be accommodating.

The ferry ride itself is a substantial part of the day, typically lasting around 7-8 hours. It offers a unique perspective of the ocean and serves as a transition between the mainland and the island of Hokkaido. For those driving, the experience of arriving in Hokkaido in the early morning or late afternoon can be quite memorable, with some travelers describing the drive south from Hokkaido in the early hours as a journey from a dream to reality.
