Volcanic Shoreline – Nagasaki, Jeju & Hakodate

About this cruise

You board in Yokohama on April 19, 2026 for 10 nights visiting Nagasaki, Jeju Island, Hakodate, Muroran and Aomori, and you come back from this kind of trip wondering why you don't do it more often. A few ports come in quick succession, which is great for sightseeing but means you'll appreciate the sea days when they arrive. Bullet trains visible from the harbour, cherry blossoms, and thousands of years of history. East Asia is a lot to take in. Hakodate alone is worth the trip, Hokkaido's star-shaped fortress and million-dollar night view. Around 11 hours per port on average, which is generous enough to go beyond the obvious. From casual buffets to proper sit-down restaurants, Diamond Princess has 12 dining spots on board, most of them included. There are enough performances, events, and social mixers on a cruise this length that you couldn't do them all if you tried. And that's a good problem. Timing-wise, spring usually means comfortable temperatures and lower prices than peak season. Worth booking. That's the short version.
