Overview
Mitsui Ocean Fuji is a relatively small luxury cruise ship operated by Mitsui O.S.K. Lines through its Mitsui Ocean Cruises brand. The vessel was originally built for Seabourn Cruise Line and entered service in 2009 as Seabourn Odyssey, becoming the first new ship delivered to Seabourn in more than a decade. Its construction began at CIMAR Shipyard, where its hull was the first produced at the newly established facility, while final outfitting was completed by T. Mariotti in Genoa, Italy. The ship was completed in May 2009, ahead of its expected schedule. It undertook sea trials on 22 May 2009, was named in Venice on 24 June, and was delivered on 29 June. It began carrying guests on 25 June 2009, shortly after its naming ceremony, on a 14-night itinerary to Istanbul. Its first operating season focused on the Mediterranean. In January 2010, the ship began its first world cruise, planned as a 108-day voyage calling at 42 ports. Under Seabourn, the vessel was positioned as an intimate luxury cruise ship rather than a mass-market resort ship. Its amenities included 11 guest decks, two swimming pools, six outdoor whirlpools, a spa, a marina platform, four restaurants, and recreational facilities such as a nine-hole miniature golf course, giant chess, and shuffleboard. Seabourn promoted the ship's large spa and generous space-per-guest ratio as distinguishing features of its design. The vessel also formed part of a new-generation Seabourn fleet that included the sister ship Seabourn Sojourn, launched in 2010. The ship received several significant refurbishments during its Seabourn career. In June 2017, Trimline carried out a five-day interior refit that refreshed staterooms, bathrooms, and a restaurant. A further ten-day dry-dock project in Genoa took place in July 2019 and updated public areas and selected suites as part of a technology and design renewal. Mitsui O.S.K. Lines announced in 2023 that it had purchased the ship for its new Mitsui Ocean Cruises operation. The acquisition reflected the vessel's suitability for smaller-scale cruising in Japanese waters, especially the Seto Inland Sea. Seabourn continued to operate the ship under a lease arrangement and completed its published itineraries through August 2024. The ship's final Seabourn voyage began on 2 September 2024, and it reached Yokohama on 26 September. It was then transferred to the new owner and sent for a major refit in Yokohama. The vessel was renamed Mitsui Ocean Fuji, taking its new name from Mount Fuji and Fuji Maru, a cruise ship previously operated by Mitsui O.S.K. Lines until 2013. It is based in Japan and began its first voyage under the new identity from Yokohama on 1 December 2024. The formal renaming took place on 7 December 2024. Its current role is therefore that of a Japanese-operated luxury cruise ship serving regional and international itineraries, with an emphasis on access to ports and waterways suited to a smaller vessel.
History
Mitsui Ocean Fuji began life as Seabourn Odyssey, a new luxury cruise ship commissioned for Seabourn Cruise Line. The keel was laid on 15 July 2007 at CIMAR Shipyard. Its hull was the first built at that shipyard, after which the vessel was transferred to T. Mariotti in Genoa for outfitting. The ship was completed in May 2009, undertook sea trials on 22 May, and was named in Venice on 24 June. T. Mariotti delivered it on 29 June 2009. Contemporary reporting cited a construction cost of approximately 550 million euros, although that figure is not independently repeated here as a current financial measure. The vessel entered guest service in June 2009 with a 14-night voyage to Istanbul and spent its first season in the Mediterranean. Seabourn appointed Captain Karlo Buer as commander in June 2008. In January 2010, Seabourn Odyssey undertook its first world cruise, planned to cover 108 days and 42 ports. Its relatively compact scale, suite-oriented accommodation, multiple restaurants, pools, whirlpools, spa, marina, and recreational spaces supported Seabourn's intimate luxury positioning. The ship was modernized several times during its original career. Trimline completed a five-day interior refit in June 2017, refreshing staterooms, bathrooms, and a restaurant. In July 2019, a ten-day Genoa dry dock delivered further technology and design updates, including work in public areas and selected suites. A major ownership and brand transition was announced in 2023. Mitsui O.S.K. Lines acquired the vessel for its Mitsui Ocean Cruises brand, while Seabourn continued operating it under lease through the end of its previously published program. The ship's final Seabourn cruise began on 2 September 2024 and ended in Yokohama on 26 September. It then underwent a major refit in Yokohama before entering Japanese service. The new name, Mitsui Ocean Fuji, refers to Mount Fuji and Fuji Maru, a former Mitsui O.S.K. Lines cruise ship operated until 2013. The ship was intended for Japan-based cruising, including the Seto Inland Sea, where its smaller size offers operational and itinerary advantages compared with much larger cruise vessels. It made its first voyage under the new name from Yokohama on 1 December 2024, with the official renaming recorded on 7 December.
