11 days, one-way from Yokohama to Tokyo

About this cruise

You won't run out of things to do on a trip this long, but you also won't feel like you have to do any of them. 11 nights from Yokohama on October 7, 2026, visiting Kobe (Osaka), Kochi and Kagoshima, with additional stops along the Japan, Korea, China & Taiwan. Last stop: Tokyo. There's a stretch of back-to-back port days, so those days are busy, but the sea days around them give you time to recharge. Karaoke bars, hot springs, and temples draped in moss. East Asia does culture and chaos in equal measure. Most ports give you about 10 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. 11 nights is long enough to build a routine on board: favourite restaurant, favourite deck chair, favourite people. It starts to feel like a floating village. If you like having options (restaurants, bars, activities, entertainment), a big ship delivers that. Pro tip: fly in the day before. Yokohama has plenty to offer, and you'll board relaxed instead of rushed. Being shoulder season helps: golden light, comfortable weather, and shorter queues at the popular spots. Good route, good ship, good timing. It all lines up.
