East China Tide – Ishigaki & Keelung from Naha

About this cruise

4 nights is all it takes to completely reset. This cruise from Naha on July 16, 2026 visits Ishigaki and Keelung and you'll feel it from day one. It splits nicely: 2 days seeing places and 0 days doing nothing at all. Tokyo's neon at one port, Kyoto's temples at the next. You cover centuries in a few days. You get around 8 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. If you like having options (restaurants, bars, activities, entertainment), a big ship delivers that. A July departure puts you in the best summer conditions: long days, warm nights, plenty of sun. 4 nights of not thinking about anything except where to eat next. That's the pitch.
