Princess Cruises’ Diamond Princess has once again deployed to her seasonal homeport of Singapore and is about halfway through her first voyage, a 16-night cruise visiting destinations in Malaysia, Thailand, and Vietnam.

The Gem-class ship, which accommodates 2,700 guests in double occupancy, is an annual visitor to Singapore, offering a series of Southeast Asia sailings before traditionally launching a Japan series in February.

In 2026, her repositioning to Yokohama (Tokyo) will begin on February 10, but first she will sail another six voyages roundtrip from Singapore.

Diamond Princess’s current itinerary features eight port calls, with just two remaining — Da Nang and Ho Chi Minh City, Vietnam, on December 19 and 21, respectively, before returning to Singapore on December 23, 2025.

Her holiday cruise, a 14-night “Malaysia, Thailand & Vietnam” sailing that departs December 23, 2025, offers guests the chance to spend Christmas and New Year’s onboard the ship as she calls at popular destinations in each country, plus Sihanoukville, Cambodia.

Cruises roundtrip from Singapore are of varying lengths and are offered into mid-February 2026, including the 10-night “Vietnam With Halong Bay,” departing on January 20, 2026. It will visit four destinations in Vietnam: Ho Chi Minh City, Nha Trang, Halong Bay, and Da Nang.

Diamond Princess will reposition to Yokohama at the conclusion of her February 10, 2026 voyage, a 14-night sailing that calls at Ho Chi Minh City and Nha Trang, Vietnam, Hong Kong, Keelung, Taipei, and Osaka and Shimizu, Japan.

The ship will launch her Japan series with the 10-night “Japan Explorer” cruise departing on February 24, 2026. The voyage will enable cruisers to immerse themselves in Japanese culture while calling at seven of the country’s ports — Beppu, Hiroshima, Shimonoseki, Nagasaki, Aburatsu, Kochi, and Toba, plus Busan, South Korea.

Diamond Princess will offer a wide variety of Japan itineraries in 2026, ranging from 9 to 20 nights.

Other Princess Cruises’ ships will make calls in Singapore in 2026-27.  Crown Princess, for example, will call in May 2026 during her 114-night world cruise, and Royal Princess will make her maiden call to the destination on October 16, 2026 during a 9-night cruise roundtrip from Singapore.

Royal Princess will also operate a 13-night cruise roundtrip from Singapore on November 10, 2026.

New Eatery Offers Japanese Specialties

Diamond Princess was constructed in Japan and designed for the Japanese market; however, the cruise line continues to enhance the ship’s cultural offerings. 

In fall 2025, a new restaurant, Makoto Ocean, was added to Diamond Princess. The eatery debuted onboard the line’s newest ships, Sun Princess and Star Princess, and was created in partnership with celebrity Chef Makoto Okuwa, who is noted for his Edomae-style sushi.

Onboard Diamond Princess, Makoto Ocean replaced the Kai Sushi venue. The new restaurant was also added to Sapphire Princess, a ship that will join Diamond Princess in the Japan market in 2027.

In August 2025, Princess Cruises announced it would double its capacity in Japan by adding Sapphire Princess to the region, joining Diamond Princess from March to December 2027. Also Japanese-built, Sapphire Princess is a sister ship to Diamond Princess.

The two ships together will sail 78 itineraries in 2027. Sapphire Princess will sail from Tokyo.
