Diamond Princess review searches usually come from cruisers trying to answer a more specific question than usual, is this one of the few older Princess ships that actually gets more interesting because of where it sails and what it was built for?
That is exactly the right question.
Diamond Princess is not just another older Princess ship hanging on in the fleet. It was built in Japan, it has a long-standing identity tied closely to Japan and Asia itineraries, and it offers a few onboard features that make much more sense in that context than they would on a generic Caribbean ship. That gives Diamond Princess a clearer personality than many ships from the same era.
My own Princess baseline still comes from one much older sailing on Ruby Princess when I was younger. What stayed with me was not some giant headline feature. It was the overall feel, calmer decks, stronger service, better dining room food, and a more grown-up atmosphere than the Carnival ships I had done before.
That memory still shapes how I think about Princess now, and it is part of why Diamond Princess stands out to me. This feels like the kind of ship that could keep that more classic Princess identity intact while also feeling more destination-specific than a lot of other older ships.
Britini and I have not sailed Diamond Princess yet, but this is exactly the kind of ship I would look at if I wanted Japan or Asia first and the ship second, while still wanting the ship to feel like part of the destination, not just transportation.

Quick Answer: Is Diamond Princess Worth Booking?
Yes, especially if Japan or Asia is the reason you are cruising in the first place.
| If This Sounds Like You | Diamond Princess Makes Sense | You May Want Another Princess Ship |
|---|---|---|
| You want a Princess ship that feels tied to Japan and Asia, not just assigned there | Yes | No |
| You prefer destination fit and ship personality over newest hardware | Yes | No |
| You want the most modern Princess class or newest public spaces | No | Yes |
| You like the idea of a more traditional Princess ship with unique regional features | Yes | No |
My read is simple: Diamond Princess can be a very smart booking for travelers who want a classic Princess ship that feels especially well matched to Japan and Asia rather than simply good enough to sail there.
Diamond Princess Review: Key Facts at a Glance
| Detail | Diamond Princess |
|---|---|
| Inaugural cruise | March 13, 2004 |
| Class | Grand Class |
| Guests | 2,710 |
| Crew | 1,100 |
| Tonnage | 115,875 |
| Decks | 18 |
| Builder | Mitsubishi Heavy Industries in Japan |
| Signature onboard feature | Izumi Japanese Bath, the largest of its kind at sea |
| Standout deployment | Japan and Asia |
Those details matter because Diamond Princess is not just another mid-2000s ship. Princess still leans heavily into the ship’s Japan-built identity, and that helps explain why it stands out more than some older ships that simply feel generic by comparison.
What You Need to Know Before You Book Diamond Princess
Diamond Princess Was Built in Japan, and It Shows
This is the single biggest reason the ship matters.
Princess still highlights the fact that Diamond Princess was built by Mitsubishi Heavy Industries in Japan and designed with features that connect closely to Japanese cruising. That is not just trivia. It shapes the ship’s identity in a way that actually matters to the booking decision.
A lot of cruise ships could be moved from region to region with minimal personality shift. Diamond Princess feels more rooted than that.
The Japan and Asia Identity Is a Real Selling Point
This is not just marketing fluff.
Princess continues to use Diamond Princess heavily in Japan and Asia, and the line specifically promotes the ship as designed for that destination. For the 2026 season, Diamond Princess returns for a longer Japan season from February through November 2026, with 50 departures, 35 itineraries, and visits to 38 destinations across three countries. That is a lot more than a token regional presence. It is a core part of the ship’s role in the fleet.
That matters because when a ship and a region are that closely linked, the onboard experience often feels more coherent.
Izumi Bath Is More Than a Gimmick
Diamond Princess is home to the Izumi Japanese Bath, which Princess describes as the largest Japanese bath of its kind at sea. It includes indoor and outdoor bathing experiences, steam rooms, saunas, and hot tubs with ocean views. That is a genuinely unusual feature in the fleet and one of the clearest reasons the ship feels different from Sapphire Princess or other older Princess ships.
This is not enough reason by itself to book the ship. But if you are already interested in Japan sailings, it helps make the ship feel like part of the trip rather than a neutral platform.
Diamond Princess Review: What This Ship Princess Does Best
It Gives You Classic Princess With a Stronger Sense of Place
This is the clearest strength.
A lot of older ships can still work fine, but they do not always feel especially tied to where they sail. Diamond Princess is more interesting because it does. It keeps the calmer, more traditional Princess identity while also feeling more connected to Japan and Asia than a standard fleet ship would.
That is a real differentiator.
It Makes More Sense for Japan Than Many Newer Ships Would
This is one of the smartest reasons to care about Diamond Princess.
A newer ship is not always the better ship if the destination fit is weaker. Diamond Princess feels like one of the few Princess ships where an older platform can still be the smarter answer because the ship’s identity and region are so closely aligned.
If I were choosing a Princess ship for Japan, this would matter a lot to me.
It Keeps the More Traditional Princess Feel Many Cruisers Still Like
Diamond Princess is still a Grand Class ship, so it offers a more traditional Princess experience than Royal Class or Sphere Class ships.
That means the appeal is less about wow-factor and more about:
- manageable scale
- calmer ship flow
- a more classic cruise atmosphere
- a destination-first mindset
For some travelers, that is a much better fit than the newer Princess direction.
How Diamond Princess Compares to Sapphire Princess and the Newer Fleet
This is the comparison that matters most.
Start with Princess cruise ship classes if you want the class-level breakdown first, then use Princess cruise ships by size and Princess cruise ships by age to see where Diamond Princess fits in the broader fleet.
| Ship | Best Reason to Book | Watch Out For |
|---|---|---|
| Diamond Princess | Strong Japan and Asia identity with unique regional features | Older hardware and less modern wow-factor |
| Sapphire Princess | More classic Princess feel with a broader itinerary-first identity | Less destination-specific personality than Diamond |
| Royal Princess | Original Royal Class identity and larger modern platform | Less region-specific and more hardware-driven |
| Regal Princess | Practical early Royal Class option | Larger and more modern-feeling than some classic-ship fans want |
| Discovery Princess | Most finished Royal Class version | A very different booking logic than Diamond |
| Sun Princess | Bold new Princess direction | Much bigger and much less traditional in feel |
| Star Princess | Newest Sphere-class follow-up | Newer hardware, but not the same Japan-specific identity |
Book Diamond Princess if
- Japan or Asia is the main reason for the trip
- you like the idea of a ship with a stronger destination identity
- you prefer classic Princess scale and atmosphere
- unique onboard features like Izumi Bath genuinely matter to you
Book Sapphire Princess if
- you want a similar classic Princess feel without the Japan-specific angle
- itinerary fit is stronger there
Book Royal Class or Sphere Class ships if
- you care more about newer hardware than destination-specific ship personality
- the ship itself matters as much as the route
If you are making that choice now, read Sapphire Princess review, Royal Princess review, Regal Princess review, Discovery Princess review, Enchanted Princess review, Sky Princess review, Sun Princess review, and Star Princess review after this one because that is where the “classic Princess versus newer hardware” decision gets much clearer.
Diamond Princess Review: Cabins and Suites on This Ship
Cabins are still part of the value here, but not in the same way as newer ships.
Princess markets Diamond Princess as a comfortable destination-first ship rather than a showcase for the latest cabin product. That means I would look at the room choice here mainly through a practical lens… balcony access, convenience, and how much private space matters on a Japan or Asia itinerary.
What matters most here:
- older cabin product than newer classes
- location still matters for convenience and noise
- private space matters more on longer or scenic sailings
- the ship’s appeal is broader than just the stateroom itself
On a ship like this, I would still pay close attention to what is above and below the room, how close you are to elevators, and whether easier access to dining, theater spaces, or outer decks matters more to your day.
Diamond Princess Review: Dining Expectations
Dining is one of the areas where Diamond Princess can feel more distinctive than a lot of older ships.
Princess highlights features like Kai Sushi and regionally connected culinary touches on Diamond Princess, and that matters because it supports the broader Japan-focused identity of the ship. Combined with the line’s more polished mainstream dining reputation, that gives Diamond Princess a dining profile that may feel more memorable than a generic older-ship lineup.
What I would expect overall:
- a solid main dining room foundation
- regionally influenced options that fit the itinerary better
- a calmer dining rhythm than party-first cruise lines
- a good fit for travelers who care about food quality and destination connection more than novelty for its own sake
Atmosphere and Onboard Feel
This is where Diamond Princess probably makes the most sense.
The ship seems built for travelers who want Princess to feel calm, familiar, and destination-friendly, but with a more specific regional personality than many ships offer. That is a useful niche.
A lot of newer ships can make the ship itself feel like the main event. Diamond Princess looks more like a ship that supports the destination while still giving you enough onboard character to remember it.
Itineraries: Why Diamond Princess Can Still Make Sense
This is one of the strongest reasons to care.
Princess’s current Japan and Asia deployment for Diamond Princess is not minor. The ship returns for a longer 2026 Japan season from February through November, sailing a broad mix of itineraries from Japanese homeports. That gives Diamond Princess one of the clearest region-ship matches in the fleet.
If I were choosing it, I would be booking Diamond Princess because the destination and ship identity fit together unusually well.
Who Diamond Princess Looks Best For
Diamond Princess looks strongest for:
- couples who want a calmer mainstream cruise
- travelers who are prioritizing Japan or Asia itineraries
- cruisers who prefer a more traditional Princess feel
- readers who want a ship with clearer destination identity
- food-focused travelers who like more regionally connected onboard touches
Who Should Skip Diamond Princess
Diamond Princess is probably not your best fit if you are looking for:
- the newest Princess class in the fleet
- the most modern public spaces
- the newest cabin product
- attraction-heavy family features
- a cruise where the ship itself needs to feel like the main attraction
That matters because Diamond Princess wins on destination fit and ship character, not on modern hardware.
Diamond Princess Review: Common Mistakes to Avoid
Treating Diamond Princess Like Just Another Older Ship
Why it is a problem: You miss the biggest reason the ship still matters… its Japan-built identity and region-specific appeal.
Extra considerations: This ship makes more sense when you see it as part of the destination, not just part of the fleet.
Better alternatives: Compare it directly with Sapphire Princess review and the Royal Class ships before assuming age tells the whole story.
Comparing It to Newer Princess Ships for the Wrong Reasons
Why it is a problem: Diamond Princess is not trying to beat Sun Princess or Star Princess on modern wow-factor.
Extra considerations: The smarter comparison is destination fit, manageable size, and classic Princess appeal.
Better alternatives: Decide first whether you want the newest ship or the ship that makes the most sense for Japan.
Ignoring How Strong the Japan Match Really Is
Why it is a problem: You can miss one of the clearest ship-region fits Princess has.
Extra considerations: Princess continues to make Diamond Princess a major Japan and Asia platform, not a secondary afterthought.
Better alternatives: Choose Diamond Princess because it fits the destination unusually well, not just because it happens to be available.
Step by Step: How to Decide Whether Diamond Princess Is Right for You
1. Decide whether Japan or Asia is the real reason for the trip
If yes, Diamond Princess gets much stronger.
2. Compare it with Sapphire Princess first
That is usually the most useful classic-Princess comparison.
3. Decide whether you want classic Princess or newer Princess
That matters more than the launch year alone.
4. Think about whether destination-specific features matter to you
If they do, Diamond Princess stands out more.
5. Choose your cabin carefully
Even on a more traditional ship, location still affects noise, convenience, and daily flow.

Jim’s Take on Diamond Princess review
Diamond Princess review comes down to one simple idea for me, this feels like the Princess ship you book when you want the destination and the ship to make sense together.
That is a real strength. Not every cruise ship has a strong identity beyond its age, class, or hardware. Diamond Princess does. It was built in Japan, it still carries that connection in meaningful ways, and Princess continues to use it as a major Japan and Asia platform. That gives the ship a stronger reason to exist than a lot of older ships have.
My one early Princess sailing on Ruby Princess still shapes how I see the line. I liked the calmer feel, the stronger service, and the sense that Princess aimed a little more upscale than the louder mainstream options I had done before.
Diamond Princess seems like the kind of ship that keeps that older-school Princess identity intact while adding a much clearer regional personality on top of it.
Britini and I have not sailed it yet, so I am not pretending this is firsthand. But if I were booking Japan with Princess, Diamond Princess would feel like one of the most logical ships in the entire fleet to consider.
Final Recommendation After Diamond Princess Review
If you want a Princess ship that feels classic, destination-friendly, and unusually well matched to Japan and Asia, Diamond Princess is absolutely worth considering.
Book it for the Japan-built identity, the Izumi Bath, the calmer Princess atmosphere, and the fact that it still feels more relevant than many older ships because its destination fit is so strong.
Skip it if you specifically want the newest class, the most modern public spaces, or a cruise where the ship itself is the main attraction.
The smartest way to think about Diamond Princess is simple: it is not the newest Princess ship. It may be one of the most destination-specific ones. Learn more facts about diamond princess.
