4 days, one-way from Sasebo to Naha
About this cruise
4 nights is all it takes to completely reset. This cruise from Sasebo on August 13, 2026 visits Yeosu, Keelung and Naha and you'll feel it from day one. The trip wraps in Naha, so you won't retrace your steps. It's a fast-paced itinerary that leans heavily toward time ashore. Good if sitting still isn't your thing. 3 countries (South Korea, Taiwan and Japan) across the Japan, Korea, China & Taiwan, each with its own character. You get around 9 hours in each port, which is enough for an excursion, lunch, and some wandering around on your own. When you're not ashore, Costa Serena holds 3,014 guests across 13 decks. It's a big ship, with plenty to keep you busy. An August departure puts you in the best summer conditions: long days, warm nights, plenty of sun. Whether you've cruised before or not, this 4-night itinerary is a genuinely good one.
