Mt Fuji, Sasebo, Jeju & Busan 8 Nights • Tokyo (Yokohama), Japan to Shanghai (Baoshan), China • Spectrum of the Seas

Yokohama is the central gateway to exploring Tokyo, a once-humble fishing village that is now one of the world's biggest, most densely populated cities. You'll find an eclectic mix of traditional shrines and soaring skyscrapers lining these neon-lit streets. Walk the Rainbow Bridge over Tokyo Bay alongside the Yurikamome Rail Line, a futuristic, operatorless train system. Then, see old Tokyo at the Imperial Palace, an Edo Castle surrounded by moats and gardens perfect for strolling. Cruise to Tokyo and head to iconic Sensoji Buddhist Temple and pass below the massive red paper lantern of the Thunder Gate. Then, unwind in Yoyogi Park, a literal forest in the heart of the city, complete with Zen gardens and a gingko tree forest.

Mt. Fuji sightseeing is the name of the game in Shimizu. If there are no obscuring clouds, head to Miho-no-Matsubara, an emerald green pine grove next to the ocean, backdropped by the soaring volcano. Spend the rest of your time picking tea in the tranquil countryside, or indulge in the freshest sushi at the Shimizu Sushi Alley in S-Pulse Dream Plaza.

Embrace the multi-cultural culinary scene of Sasebo and savor everything from burgers with a Japanese twist to succulent oysters pulled fresh from the sea. Visit the beautiful Uragashira Hikiage Peace Park, marvel at the tulips of Huis Ten Bosch and see Sasebo's 99 Islands. Get off the beaten path and head out to SASPA and spend a relaxing soak in a mineral hot spring (onsen).

Immerse yourself in Jeju's brilliant green landscape and breathtaking peaks. Tackle the challenge of hiking up the dormant volcano Mount Hallasan volcano, or stroll through forested walking trails to the mystical Cheonjeyeon Falls. Then, have a bit of fun exploring the quirky Teddy Bear Museum. Or relax in an herb sauna or jjimjilbang, a Korean bathhouse, at Jeju WaterWorld.

Get a sense of what South Korea looked like in 678 A.D. at the elaborate Beomeosa Temple — its three-story red pagoda is set at the edge of dramatic Mount Geumjeongsan. Then, head to Busan city center and stroll the white sands of Haeundae Beach. Alongside the shoreline, you'll find plenty of restaurants and shops — pop into a local bakery for eomuk, the crispy fish cake the region is famous for.

Most international flights arrive at Pudong Airport. Take the bullet train into the city; it takes only 8 minutes between the airport and Longyang Road Station. From there, check out Longhua Temple: You'll recognize its two-meter-tall copper bell from Steven Spielberg's "Empire of the Sun." Then, marvel at the modern skycrapers of Pudong — head to the Oriental Pearl Tower with its three distinctive spheres and get a 360-degree view of the city from the observation deck.
