Nagoya is Japan’s fourth largest city, though it remains well off the radar of most tourists, overshadowed by nearby Tokyo and Kyoto. The city is an important manufacturing hub, home to companies including Toyota and Lexus, and sights include a fascinating railway museum featuring maglev and ‘shinkansen’ bullet trains.

The small, laid back city of Kochi is situated on the south coast of Shikoku island, an important place of pilgrimage for Japanese Buddhists. Three of the 88 temples on the pilgrimage route are in Kochi, and the city is also known for its elegant 17th century hilltop castle.

The friendly southern Japanese city of Kagoshima enjoys a balmy climate, and sits just across the bay from the very active Sakurajima volcano, which erupts so regularly that an ‘ash forecast’ is included in local weather reports.

Three days after Hiroshima was flattened by an atomic bomb, Nagasaki suffered the same horrifying fate. The reconstruction of both cities has been quite extraordinary; Nagasaki today is a vibrant, cosmopolitan place, with a fascinating history that goes back a lot further than 1945.

Busan is South Korea’s second biggest city and one of the world’s busiest container ports, but it’s an easygoing place with a discernibly different character to Seoul. Haeundae beach is a popular summer holiday destination for Koreans, while the pungent Jagalchi market sells every type of fish and sea creature imaginable.

On 6 August 1945 the world witnessed the terrifying power of nuclear weapons for the first time, unleashed on the unsuspecting Japanese city of Hiroshima. The modern city's sobering Peace Memorial Park commemorates that fateful day, which left more than 140,000 dead.

Small in size and cosmopolitan in its outlook, Kobe is a thoroughly pleasant city with a long and distinguished history as one of Japan’s main trading ports. Kobe’s past as a commercial hub is reflected in its architecture, with a number of unusually European-looking houses, as well as a charming, if slightly touristy, Chinatown.

Shimizu is one of the most spectacular ports in Japan, a sweeping bay in the shadow of the iconic Mount Fuji. You can spend some time admiring the views and wandering through peaceful pine groves, or visit the unique Shimizu Sushi Museum at the S-Pulse Dream Plaza shopping mall.

In a state of constant renewal and forever looking to the future, densely populated Tokyo is a dazzling introduction to Japan and its utterly unique culture. With more neon than Las Vegas and more Michelin stars than Paris, it’s a real assault on the senses.

Sendai is the largest city in the Tohoku region, founded in the 16th century by the powerful samurai lord Date Masamune. His legacy lives on in the ruins of Sendai Castle, heavily damaged by Allied bombing during the Second World War. The city also plays host to the colourful Tanabata Matsuri festival every summer.

Situated at the southern tip of Hokkaido, Hakodate was one of the first Japanese ports to open up to international trade in the 19th century, and a scattering of European-style buildings remain. Take a ride on the historic streetcar, tuck into delicious seafood or enjoy a revitalising dip in an onsen (hot spring).

The charming port town of Otaru has a notable history, playing an important role in the herring trade during the 19th century, and this is reflected in the stone warehouses alongside the picturesque canal.

Kodiak is known as Alaska’s ‘Emerald Isle’ thanks to the lush green countryside, a landscape crisscrossed by gushing salmon-filled streams that provides a home to around 3,000 Kodiak bears, the world’s largest. Ships dock in Kodiak city, an important fishing port with a fascinating Russian heritage.

The little town of Homer is situated on the beautiful Kenai Peninsula, surrounded by spectacular mountain scenery. The town has something of a counter-cultural vibe, and is also known for the unusual geological feature known as the Spit, a sliver of land that stretches 4½ miles into Kachemak Bay.

The Alaskan city of Whittier is home to just 200 people; remarkably, nearly all of them live in a single building, the Begich Towers. You can hike in the Chugach National Forest, try sea kayaking amongst the glaciers of Prince William Sound, and look for wildlife including bald eagles, whales and sea otters.

The port at Icy Strait Point was created to ensure that indigenous communities benefit from cruise tourism in Alaska, and the facility is owned by the local Tlingit people. Here you can learn about Alaska’s native culture and enjoy guided nature walks, whale watching trips or shopping for local crafts.

Ketchikan is a great introduction to Alaska’s natural attractions, situated at the foot of towering Deer Mountain and within easy reach of the Misty Fjords. The colourful wooden buildings of Creek Street, the old red light district, are a reminder of Ketchikan’s former status as a rough and ready frontier town; these days, things are rather more civilised!
