Japan first, with selective voyages beyond
The programme is anchored in Japanese homeports and follows the country’s seasons, festivals, islands and regional ports. Short domestic circuits sit beside calls in Korea and Taiwan, while selected longer voyages extend into the South Pacific, Tahiti and Australia. This concentration gives Mitsui Ocean Cruises a clear geographic character: even when an itinerary travels beyond Japan, the voyage remains framed through Japanese service, food and cultural interpretation rather than being adapted into a generic international cruise.
