Mitsui Ocean Cruises Unveils 2027 Small-Ship Voyages on Mitsui Ocean Fuji and Mitsui Ocean Sakura: What Tourists Need to Know

Those dreaming of Japan and Korea in a slower, more intimate pace than most will love the brand new 2027 program of Mitsui Ocean Cruises, a program seemingly created with time spent gazing over landscapes rather than crossing sights off a list. The line has opened sales on an extensive season of 68 itineraries on sister-ships Mitsui Ocean Fuji and Mitsui Ocean Sakura that chart cherry blossoms, firework festivals, snow festivals and autumn hues across the archipelago.

At the heart of the programme is the brand’s commitment to connecting guests with regional culture, food and nature while staying close to Japan’s shores in a distinctly Japanese onboard atmosphere. Sailing with a deliberately small-ship philosophy, the two-vessel fleet focuses on lesser-visited ports and hidden harbours that larger vessels simply cannot reach.

Two-ship fleet dedicated to Japan

Mitsui Ocean Cruises, operated by MOL Cruises, positions its fleet as a bridge between Japan’s maritime heritage and modern luxury, with both Mitsui Ocean Fuji and Mitsui Ocean Sakura sailing under the Japanese flag. Mitsui Ocean Fuji, formerly Seabourn Odyssey, launched her inaugural season for the brand in late 2024 with roundtrip voyages from Tokyo, Yokohama and other major ports, introducing an all-suite ship where Japanese design, wellness and cuisine are central to the experience.

Mitsui Ocean Sakura, the line’s second all-suite vessel and former Seabourn Sojourn, is due to enter service in September 2026 with 29 debut cruises before rolling into full-year deployment. Both ships offer spacious suites, multiple restaurants serving Japanese and international dishes, bars and lounges, plus spa and wellness facilities, with Sakura adding features such as a sushi bar and foot bath to reinforce the sense of place at sea.

Mitsui Ocean Fuji: seasonal circuits around Japan and Korea

In 2027, Mitsui Ocean Fuji will operate seven itineraries around Japan, with embarkation and disembarkation in key cities including Yokohama, Kobe and Hakata. Several routes weave through the scenic Seto Inland Sea, calling at ports such as Matsuyama and Hiroshima, while late-spring departures include two back-to-back circumnavigations of Japan roundtrip from Yokohama that reach the Sea of Japan, Iwanai and Hokkaido.

Highlighted examples from the 2027 programme include:

• Spring Gardens of Japan & Korea (6 nights): a Kobe–Yokohama sailing visiting Busan, Hososhima and Shingu, ideal for travellers following early blossoms and coastal shrines.
• Northern Japan in Bloom (12 nights): a Yokohama round-trip that traces a floral arc through Sasebo, Busan, Tottori, Nanao, Ryotsu, Oga, Otaru and Hakodate as spring moves north.
• Golden Week (10 nights): a celebratory Yokohama roundtrip to Tokachi, Esashi, Akita, Toyama Shinko and Sokcho, timing Japan small ship cruises to one of the country’s liveliest holiday periods.
• Silver Week (9 nights): sailing Tokyo to Yokohama via Shodoshima, Shingu, Tomonoura and Saiki, linking historic ports and island communities in late-September sunshine.

Across these voyages, the line pairs port days with a shore excursion programme designed to highlight hot springs, gardens, local cuisine and traditional districts ashore.

Mitsui Ocean Sakura: 61 departures and festival-focused escapes

Mitsui Ocean Sakura will shoulder the lion’s share of departures in 2027, with 61 itineraries that lean heavily into short-break travel, more than half lasting just one to three nights. This approach is intended to appeal to guests seeking weekend-style escapes or add-on coastal journeys around longer land trips in Japan.

Signature seasonal routes showcase Japan and Korea at their most atmospheric:

• Sapporo Snow Festival (6 nights): a Yokohama roundtrip calling at Tomakomai, Sendai and Oarai, giving guests easy access to Hokkaido’s famous winter celebration and snow-covered streets.
• Golden Week (8 nights): an itinerary from Yokohama to Miyazaki, Tanegashima (Nishinoomote), Koshikijima, Aokata and Kure, blending space history, island scenery and coastal towns.
• Tohoku Festival & Tateyama Fireworks (7 nights): sailing Tokyo–Akita–Aomori–Tateyama–Yokohama, timed around local festivals and summer fireworks displays.
• Shimonoseki Fireworks (9 nights): a Yokohama roundtrip via Jeju Island, Shimonoseki, Komatsushima, Kiitanabe and Kumanooki, pairing Korean island culture with illuminated Japanese harbours.

The deployment underlines Mitsui Ocean Cruises’ strategy of using Mitsui Ocean Sakura to deliver flexible Japan coastal voyages that still feel immersive, even on shorter stays.

Onboard style: Japanese omotenashi at sea

On both Mitsui Ocean Fuji and Mitsui Ocean Sakura, the onboard experience is crafted to reflect Japanese concepts of wellbeing and hospitality rather than generic luxury-cruise styling. Suites feature balconies and thoughtful touches such as full bathtubs and shower toilets, while public spaces include multiple dining venues, lounges, pools, whirlpools and wellness facilities that encourage guests to slow down between port days.

The line emphasises locally rooted cuisine, with menus showcasing Japanese flavours alongside international favourites, and shore excursions curated to bring guests into contact with regional producers, artisans and landscapes. According to the company’s leadership, the cruise business is framed as a way to support port communities around Japan while offering travellers “beautiful encounters” with the country’s coastline and island life.

Why these Japan and Korea itineraries will appeal to travellers

For travellers weighing up Mitsui Ocean Cruises 2027 options against other Japan and Korea cruise holidays, the draw is a combination of intimacy, access and cultural depth. The small-ship scale allows for calls at compact harbours, while itineraries are structured around seasonal moments such as cherry blossoms, snow festivals and fireworks that feel inherently photogenic and experiential.

Many guests are likely to appreciate that most voyages are roundtrip from major gateways like Yokohama or Tokyo, simplifying pre- and post-cruise travel, with select routes also tapping ports such as Kobe and Hakata. For those who already love Japan and for first-timers alike, the 2027 programme positions Mitsui Ocean Fuji and Mitsui Ocean Sakura as floating bases for discovering the country’s coastal character at a pace that leaves room for serendipitous views from the rail as much as shore-side sightseeing.
