Cobalt Tides – Nagasaki, Busan & Hakodate

About this cruise

8 nights is that sweet spot where you actually start to relax. This sailing from Yokohama on July 28, 2026 visits Nagasaki, Busan, Aomori and Hakodate and doesn't try to cram in too much. The shape of this trip works well: open water on either side with 4 port calls clustered in the middle. Bullet trains visible from the harbour, cherry blossoms, and thousands of years of history. East Asia is a lot to take in. Keep an eye out for Hakodate: Hokkaido's star-shaped fortress and million-dollar night view. Around 12 hours per port on average, which is generous enough to go beyond the obvious. There are 12 restaurants on Diamond Princess, so you'd need to double up a few evenings to try them all in 8 nights. Yokohama itself is worth spending some time in. Don't just treat it as a departure point. The timing works well too: warm evenings on deck, late sunsets, and a lively atmosphere. That's 8 nights well spent.
