Costa Serena’s New Asia Routes Link Six Countries by Sea

Costa Cruises is preparing an expanded series of Asia sailings aboard Costa Serena that knit together Japan, South Korea, China, Vietnam, Thailand and Singapore, positioning the 2026 program as one of the most wide-ranging regional deployments currently on offer in the region.

Expanded Costa Serena Deployment Across East and Southeast Asia

Publicly available information indicates that Costa Serena will remain based in Asia for most of 2026, operating alternating 14 day itineraries that together connect major ports across East and Southeast Asia. One itinerary is focused on Japan, Taiwan and South Korea, while the other highlights Vietnam, Thailand, Singapore, Brunei and the Philippines. This mix effectively links key cultural hubs such as Tokyo and Busan with tropical gateways like Koh Samui and Singapore.

The expansion follows earlier winter 2025 to 2026 sailings that already combine Hong Kong with destinations in Japan and South Korea, as well as a separate route that runs between Hong Kong, Vietnam, Thailand, Singapore and onward into the broader ASEAN region. These programs are built around fly and cruise packages from long haul markets and short segment options for regional travelers looking for four to ten night trips.

Industry coverage of Costa’s deployment strategy suggests that the line is using Costa Serena as a flexible platform to test demand across multiple source markets. Embarkation is offered in several cities including Tokyo, Hong Kong, Singapore, Busan and Nagasaki on different departures, helping to connect travelers from Northeast Asia, Southeast Asia and Europe onto the same voyages.

Cultural Highlights From Tokyo to Shanghai and Beyond

The Japan and Korea focused itineraries emphasize slow travel through some of the region’s most historic ports. Sample schedules published by cruise industry outlets show Costa Serena sailing from Tokyo’s Yokohama cruise terminal to Kobe for an overnight call, then on to Kochi, Kagoshima, Nagasaki, Kanazawa and Hakodate, with a stop in Busan en route. These calls combine major cities with smaller coastal communities, offering access to castles, hot spring regions and preserved merchant districts.

Another version of the route is centered on Seoul’s port of Incheon, followed by Busan and a series of southern Japanese ports such as Sasebo, Yatsushiro, Kagoshima and Nagasaki, before concluding with an overnight stay in Shanghai. Reports indicate that this pattern is designed to showcase both Korea’s urban waterfronts and Japan’s Kyushu region, where volcanic landscapes and waterfront promenades sit within reach of the pier.

Shanghai’s inclusion as a turnaround or final port on select departures reflects a gradual rebuilding of mainland China as a cruise destination. While the Chinese market was among the last in Asia to reopen fully, current schedules show the city returning as a marquee call, giving travelers a chance to transition overland to onward air connections throughout the region.

Vietnam, Thailand and Singapore on a Tropical Circuit

The second major pillar of Costa Serena’s Asia program runs south from Hong Kong through Vietnam and Thailand to Singapore, with some departures continuing to Brunei and the Philippines. Itineraries highlighted in trade publications feature coastal cities such as Nha Trang and Phu My in Vietnam, the island of Koh Samui in the Gulf of Thailand, and long days in port at Singapore.

These calls are framed around both scenic cruising and cultural immersion. Nha Trang and Phu My act as gateways to beach resorts and to the historic centers of Ho Chi Minh City and the Mekong Delta, while Koh Samui offers smaller scale island life, temple visits and viewpoints over the Gulf. In Brunei, Bandar Seri Begawan appears on schedules as an extended stop, giving time to visit its waterfront stilt villages and ornate mosques.

Singapore functions as a key embarkation and disembarkation point on these departures, supported by its air connectivity and established cruise infrastructure. Coverage in regional cruise media notes that the city’s role helps link Southeast Asia routes with long haul markets, allowing travelers to join one leg from Hong Kong to Singapore or continue onward to additional ports in the Philippines.

Onboard Experience and Practical Booking Details

Costa Serena is a mid sized ship originally built for the Asian and European markets, with a passenger capacity in the several thousand range and a design that mixes Italian themed interiors with family focused amenities. Refurbishment work scheduled for late 2025 is expected to refresh public areas and cabins ahead of the longer Asia season, according to trade reports summarizing the company’s deployment announcements.

For travelers, the key practical detail is the structure of the itineraries. The alternating 14 day programs are often sold both as full voyages and as shorter segments of four to ten days, enabling guests to tailor their trip length. Embarkation in multiple ports gives additional flexibility, but also means that not every traveler will experience the full loop that links Japan, Korea, China, Vietnam, Thailand and Singapore on a single continuous sailing.

Published schedules also highlight that these cruises typically include several sea days between clusters of ports, which can appeal to travelers seeking a mix of onboard downtime and intensive sightseeing ashore. However, observers note that visa requirements, health regulations and local port policies can still affect final itineraries, so travelers are advised to review the latest pre departure information carefully.

Looking Ahead: World Cruise and Evolving Asia Cruise Market

The 2026 Asia season for Costa Serena is scheduled to culminate in a 66 day world cruise departing from Tokyo in October 2026. The voyage, outlined in cruise industry briefings, crosses Asia, Oceania and South America before ending in Buenos Aires, effectively repositioning the ship out of the region for a subsequent South America and Mediterranean program.

This world cruise underscores how Costa is using Asia both as a stand alone destination and as a strategic link in longer global routes. By first concentrating on regional itineraries that connect Japan, South Korea, China, Vietnam, Thailand and Singapore, then extending into a multi continent journey, the line is attempting to appeal to both first time cruisers in Asia and experienced guests seeking extended voyages.

More broadly, the program reflects a wider normalization of cruise deployment in Asia after the disruptions of the early 2020s. Other international brands are also rebuilding Japan, Korea and Southeast Asia seasons, but Costa Serena’s alternating itineraries stand out for the way they braid together Northeast and Southeast Asia. For travelers planning 2025 and 2026 trips, these routes offer an opportunity to experience a cross section of the region’s cultures and coastlines in a single extended voyage by sea.
