Costa Cruises announced two new itineraries aboard the Costa Serena, exploring Asia during the winter 2025-26 season, according to a company statement. 

The first itinerary is a 15-day journey that explores Japan. The full itinerary includes Hong Kong, Keelung (Taiwan), Naha (Japan), Kagoshima (Japan), Tokyo (Japan), Kobe (Japan), Nagasaki (Japan), Busan (South Korea) and Hong Kong.

The second itinerary sails through South-East Asia for 15 days. Destinations included in this itinerary are Hong Kong, Nha Trang (Vietnam), Phu My (Vietnam), Koh Samui (Thailand), Singapore, Bandar Seri Begawan (Brunei), with a 12-hour long stopover, Puerto Princesa, Palawan (Philippines) and Hong Kong. 

The new Asia itineraries are available from November 21, 2025, through January 30, 2026, departing from Hong Kong and Tokyo.

 The two itineraries can be combined into a single 28-night holiday, visiting all 14 destinations on the two routes. The ideal solution, for example, to celebrate the end of 2025 and the beginning of the New Year. In addition, there will be the possibility of extending your stay in the destinations by choosing the dates of the flights of your preference, independently of those determined for the cruise.

Travelers with less time for exploration can opt for a one-week sailing instead.
