5 days, one-way from Hakata-Fukuoka City to Naha

About this cruise

Some of the best trips are the ones you barely had to plan. 5 nights from Hakata (Fukuoka) on July 23, 2026, visiting Busan, Keelung and Naha, and you're home before the laundry piles up. Last stop: Naha. You're in port almost every day, so pack shoes you can actually walk in. The route threads through 3 countries along the Japan, Korea, China & Taiwan coast: South Korea, Taiwan and Japan. Of the stops, Keelung tends to be the one people talk about: Taiwan's rainy harbour of night-market magic. Roughly 8 hours ashore per stop. No need to rush. Costa Serena carries up to 3,014 guests over 13 decks. Multiple pools, a theatre, and more restaurants than you'll get through. Hakata (Fukuoka) itself is worth spending some time in. Don't just treat it as a departure point. And July means long, warm days. Good for the ports, good for the pool. Sometimes the best trips are the ones you just go ahead and book.
