Day 1 Seattle, Washington, United States

Seattle is a scenic seaport city in western Washington, situated on an isthmus between Puget Sound to the west and Lake Washington to the east. It is the largest city in Washington. Five pioneer families from Illinois first settled the area in 1851, and named the town after a friendly Suquamish Indian chief. It was incorporated as a city in 1869, and grew quickly after the Great Northern Railway arrived in 1893, especially during the Alaska Gold Rush of 1897. When the Panama Canal opened in 1914, Seattle became a major Pacific port of entry, and today it is the region's commercial and transportation hub and the centre of manufacturing, trade, and finance, with an estimated 684,451 residents as of 2015.

Day 3 Juneau, Alaska, United States

Juneau, Alaska's capital and third-largest city, is on the North American mainland but can't be reached by road. Bounded by steep mountains and water, the city's geographic isolation and compact size make it much more akin to an island community such as Sitka than to other Alaskan urban centers, such as Fairbanks or Anchorage. Juneau is full of contrasts. Its dramatic hillside location and historic downtown buildings provide a frontier feeling, but the city's cosmopolitan nature comes through in fine museums, noteworthy restaurants, and a literate and outdoorsy populace. The finest of the museums, the Alaska State Museum, is scheduled to reopen in May 2016 on its old site as the expanded Alaska State Library, Archives, and Museum (SLAM) following several years of planning and exhibit research. Another new facility, the Walter Soboleff Center, offers visitors a chance to learn about the indigenous cultures of Southeast Alaska–-Tlingit, Haida, and Tsimshian. Other highlights include the Mt. Roberts Tramway, plenty of densely forested wilderness areas, quiet bays for sea kayaking, and even a famous drive-up glacier, Mendenhall Glacier. For goings-on, pick up the Juneau Empire (www.juneauempire.com), which keeps tabs on state politics, business, sports, and local news.

Day 4 Hubbard Glacier, United States

This is one of those places that words, photos and videos, do not do justice and just has to be seen to be experienced. Huge, majestic and imposing, the Hubbard Glacier is the iconic Alaskan experience. Towering above the ship, the glacier reaches around 11,000 feet at its highest altitude point and measures almost 76 miles long and about five miles wide. Routinely calving off icebergs the size of skyscrapers , the spectacle of watching – and hearing – the thunderous blocks of ice hit the water is something that needs to be experienced at least once in a lifetime. From pure white, to arctic to glacier blue the ice absorbs every colour giving it an exceptionally lovely hue that is impossible to reproduce. Wrap up warm as the cooling, soothing and perfect breeze compliments what is surely the highlight of this incredible journey.

Day 5 College Fjord, Alaska, United States

College Fjord in the northern sector of Prince William Sound, is considered one of the most scenic fjords in the world with spectacular glacier viewing. . There are over a dozen major glaciers in the fjord, all surrounded by rugged snow-capped mountains. It is possible from one point to see eight glaciers at once. College Fjord was discovered in 1899 during the Harriman Expedition. Edward Henry Herriman, a millionaire railroad tycoon, set sail with 125 other passengers and crew, including 23 of esteemed scientists from several Ivy League schools, to explore the fjords of Alaskan. The scientists named the glaciers in this fjord after their Ivy League alma maters and their sister schools. Those names include Amherst, Barnard, Bryn Mawr, Harvard, Smith, Vassar, and Yale. The glaciers of the northwest side feature names of women's colleges and those of the southeast side are names of men's colleges.

Day 6 Whittier, United States

The tiny city of Whittier has just over 200 residents. It's around 58 miles southeast of Anchorage in Alaska.

Day 16 Yokohama, Japan

In 1853, a fleet of four American warships under Commodore Matthew Perry sailed into the bay of Tokyo (then Edo) and presented the reluctant Japanese with the demands of the U.S. government for the opening of diplomatic and commercial relations. The following year Perry returned and first set foot on Japanese soil at Yokohama—then a small fishing village on the mudflats of Tokyo bay. Two years later New York businessman Townsend Harris became America's first diplomatic representative to Japan. In 1858 he was finally able to negotiate a commercial treaty between the two countries; part of the deal designated four locations—one of them Yokohama—as treaty ports. In 1859 the shogunate created a special settlement in Yokohama for the growing community of merchants, traders, missionaries, and other assorted adventurers drawn to this exotic new land of opportunity. The foreigners (predominantly Chinese and British, plus a few French, Americans, and Dutch) were confined here to a guarded compound about 5 square km (2 square miles)—placed, in effect, in isolation—but not for long. Within a few short years the shogunal government collapsed, and Japan began to modernize. Western ideas were welcomed, as were Western goods, and the little treaty port became Japan's principal gateway to the outside world. In 1872 Japan's first railway was built, linking Yokohama and Tokyo. In 1889 Yokohama became a city; by then the population had grown to some 120,000. As the city prospered, so did the international community and by the early 1900s Yokohama was the busiest and most modern center of international trade in all of East Asia. Then Yokohama came tumbling down. On September 1, 1923, the Great Kanto Earthquake devastated the city. The ensuing fires destroyed some 60,000 homes and took more than 40,000 lives. During the six years it took to rebuild the city, many foreign businesses took up quarters elsewhere, primarily in Kobe and Osaka, and did not return. Over the next 20 years Yokohama continued to grow as an industrial center—until May 29, 1945, when in a span of four hours, some 500 American B-29 bombers leveled nearly half the city and left more than half a million people homeless. When the war ended, what remained became—in effect—the center of the Allied occupation. General Douglas MacArthur set up headquarters here, briefly, before moving to Tokyo; the entire port facility and about a quarter of the city remained in the hands of the U.S. military throughout the 1950s. By the 1970s Yokohama was once more rising from the debris; in 1978 it surpassed Osaka as the nation's second-largest city, and the population is now inching up to the 3.5 million mark. Boosted by Japan's postwar economic miracle, Yokohama has extended its urban sprawl north to Tokyo and south to Kamakura—in the process creating a whole new subcenter around the Shinkansen Station at Shin-Yokohama. The development of air travel and the competition from other ports have changed the city's role in Japan's economy. The great liners that once docked at Yokohama's piers are now but a memory, kept alive by a museum ship and the occasional visit of a luxury vessel on a Pacific cruise. Modern Large as Yokohama is, the central area is very negotiable. As with any other port city, much of what it has to offer centers on the waterfront—in this case, on the west side of Tokyo Bay. The downtown area is called Kannai (literally, "within the checkpoint"); this is where the international community was originally confined by the shogunate. Though the center of interest has expanded to include the waterfront and Ishikawa-cho, to the south, Kannai remains the heart of town. Think of that heart as two adjacent areas. One is the old district of Kannai, bounded by Basha-michi on the northwest and Nippon-odori on the southeast, the Keihin Tohoku Line tracks on the southwest, and the waterfront on the northeast. This area contains the business offices of modern Yokohama. The other area extends southeast from Nippon-odori to the Moto-machi shopping street and the International Cemetery, bordered by Yamashita Koen and the waterfront to the northeast; in the center is Chinatown, with Ishikawa-cho Station to the southwest. This is the most interesting part of town for tourists. Whether you're coming from Tokyo, Nagoya, or Kamakura, make Ishikawa-cho Station your starting point. Take the South Exit from the station and head in the direction of the waterfront.
