East China Tide – Ishigaki & Keelung from Naha

About this cruise

This is the kind of trip that just works. 4 nights from Naha, visiting Ishigaki and Keelung, sailing July 31, 2026, and nothing about it feels forced. That gives you 2 days in port and 0 at sea, enough of each to find a rhythm. Karaoke bars, hot springs, and temples draped in moss. East Asia does culture and chaos in equal measure. 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. Pro tip: fly in the day before. Naha has plenty to offer, and you'll board relaxed instead of rushed. It's peak season, so the weather is at its best and the ship will be full. That's part of the fun. Whether you've cruised before or not, this 4-night itinerary is a genuinely good one.
