THE DIAMOND PRINCESS

I asked Google AI what is the most popular cruise ship in Japan:

Several major international cruise lines operate an extended season of sailings around Japan, attracting both Japanese and international travelers. 

• 
  Diamond Princess: This ship is arguably the most famous international vessel to homeport in Japan. Princess Cruises has a significant and long-standing presence in the Japanese market, offering a vast number of itineraries and sailings around the islands.

So I searched further and found:  The Best Japan Cruises 2026:  An Insider's Guide to Unforgettable Cultural Experiences.

Want to experience authentic Japanese culture and festivals—but not sure where to start?
