East Sea Dash – Yeosu, Keelung & Naha

About this cruise

It's the kind of trip that's easy to say yes to. 4 nights from Sasebo on August 13, 2026, visiting Yeosu, Keelung and Naha. You get off in Naha, which is a good excuse to tack on a few days on land. There's a new port nearly every day, 3 days ashore total, so you're kept busy. The Japan, Korea, China & Taiwan route takes in South Korea, Taiwan and Japan, 3 countries, and the differences show up in the food, the architecture, and the mood. Most ports give you about 9 hours, so you can do more than just tick off the main sights. As for the ship itself, Costa Serena: 3,014 guests, 13 decks. Entertainment, dining, and enough space that it never feels cramped. If you like having options (restaurants, bars, activities, entertainment), a big ship delivers that. It's peak season, so the weather is at its best and the ship will be full. That's part of the fun. 4 nights of not thinking about anything except where to eat next. That's the pitch.
