Imperial Circuit – Keelung, Busan & Nagasaki

About this cruise

A 18-night sailing gives you something shorter trips can't: the feeling that you're not just visiting places but actually living somewhere else for a while. This one leaves Yokohama on June 23, 2026 and visits Keelung, Ishigaki and Naha, with additional stops along the Japan, Korea, China & Taiwan. You ease into this one, with a few sea days up front to find your rhythm before the 9 port calls start. The route threads through 3 countries along the Japan, Korea, China & Taiwan coast: Taiwan, Japan and South Korea. Ishigaki alone is worth the trip, Japan's tropical gateway to Yaeyama coral reefs. Around 10 hours per port on average, which is generous enough to go beyond the obvious. Diamond Princess has 12 restaurants on board, which means you could eat somewhere different nearly every night. The longer time on board means you'll catch several shows, themed nights, and start feeling like a regular at your favourite bar. 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. Worth booking. That's the short version.
