Mitsui Ocean Cruises announced the upcoming retirement of the cruise line’s 422-guest Nippon Maru.

The cruise ship will officially retire from the fleet on May 10, 2026, in Yokohama.

The ship first entered service in 1990 and has since traveled 2,877,642 nautical miles – approximately 133 times around the earth – sailing over 2,000 cruises, hosting more than 600,000 guests, and visiting over 400 ports in and out of Japan, the company said.

“With full hearts and deep gratitude, we bid a bittersweet farewell to Nippon Maru, which has served us well for over 35 years,” said Tsunemichi Mukai, president of Mitsui Ocean Cruises.

“Though a difficult decision, it is time to retire her for operational and economic reasons. We’re excited to carry on her legacy of fine hospitality aboard our new luxury ships, Mitsui Ocean Fuji and our recently announced second ship, where many of our cherished crew will continue to serve.”

The retirement of the Nippon Maru will make way for the company’s second recently acquired ship, the current Seabourn Sojourn, which joins the fleet in late 2026.
