Diamond Princess entered service in 2004 as a Gem-class variant of the Grand-class design, built wider than her sisters specifically to serve the Japanese market — and she remains one of the very few ships purpose-designed for a specific region rather than adapted to it. She's homeported in Yokohama for most of the year, sailing round-trip Japan, South Korea and wider Asia itineraries, with a winter season from Singapore covering Southeast Asia. At 115,875 gross tons and under 2,700 guests, she's smaller and more intimate than most modern Princess ships, with a loyal following among cruisers who value her destination focus and distinctive onboard culture over mega-ship scale.

✦ The standout feature

Izumi Japanese Bath — the largest bathhouse at sea, an 818-square-metre traditional onsen with indoor and outdoor stone-and-timber bathing areas, steam rooms and ocean-view hot tubs, found on no other cruise ship in the world.

  • Cruisers wanting a genuine onsen bathhouse experience
  • Fans of smaller, more intimate ships
  • English-speaking travellers comfortable with a strong Japanese guest mix

Guests wanting the newest MedallionClass tech or mega-ship entertainment scale. Diamond Princess is an older, purpose-built ship whose onboard culture and signage reflect her large Japanese-speaking guest base, which not everyone finds equally comfortable.

Frequently Asked Questions

What is the Izumi Japanese Bath on Diamond Princess?
Izumi is a traditional Japanese onsen-style bathhouse — the only one at sea. It has indoor bathing areas (swimwear not permitted, gender-separated by day) modeled on Japanese bathing customs, plus an outdoor tub where swimwear is required. It's built from stone and timber with large ocean-view windows.
Where does Diamond Princess sail?
She's homeported in Yokohama, Japan for most of the year, sailing round-trip itineraries around Japan, South Korea, Taiwan and wider Asia. In winter she typically repositions to Singapore for Southeast Asia sailings, visiting destinations like Thailand, Malaysia and Vietnam.
Why was Diamond Princess built differently from other Grand-class ships?
Diamond Princess and sister ship Sapphire Princess were purpose-built for the Japanese market with a wider beam (123 ft vs. 118 ft on other Grand-class ships) and Japan-specific features like the Izumi Japanese Bath, giving them their own 'Gem-class' designation within the Grand-class family.
Is Diamond Princess a modern ship with MedallionClass technology?
She's one of Princess's older ships, launched in 2004, and her MedallionClass retrofit is more limited than on newer vessels. Guests get core wearable-tech benefits, but the ship's real draw is her destination-first Asia deployment and one-of-a-kind onsen, not cutting-edge tech.
