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!

The breathtaking Misty Fjords National Monument is a 3,570-square-mile swathe of virgin forest and plunging fjords, just to the east of Ketchikan. As the name suggests, the fjords are often cloaked in a fine mist, and the wilderness is home to bears, bald eagles, whales and more.

Back in its 19th century heyday Wrangell was a lawless gold rush town, and it's still a little rough around the edges, but it's also a very welcoming place, ideal for exploring the surrounding Alaskan wilderness. Take a trip to the nearby Anan Wildlife Observatory for the chance to see black and brown bears at close proximity.

Beautifully located next to the longest fjord in North America, Haines is one of the most attractive cruise ports in Alaska, surrounded by mountains, forests and glaciers. It’s also home to the world’s largest concentration of bald eagles, and a great place to spot grizzly bears.

Alaska's state capital is isolated and remote, accessible only by plane or by boat thanks to its dramatic hillside location. The wild hinterland is thick with forest, sculpted by the glaciers of the Juneau Ice Field, while down at the water's edge the harbour bustles with fishing boats and seaplanes.

Sitka was founded by Russian fur traders in 1799 as the city of New Archangel, and there is still a discernible Russian influence here, including the distinctive St Michael’s Orthodox Cathedral. The town also enjoys spectacular natural surroundings, facing the Pacific Ocean and dramatic Mount Edgecumbe.

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.

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.

The small coastal town of Shingu is home to the Kumano Hayatama Taisha, one of three Shinto shrines connected by a network of ancient pilgrimage routes. The surrounding countryside is home to waterfalls, fast-flowing rivers and the dramatic Dorokyo Gorge, and is a popular area for hiking, rafting and scenic boat trips.

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.

The coastal city of Karatsu was a key port for trade with China and Korea thanks to its proximity to the Korean peninsula, and is known for the quality of its pottery. Local attractions include the large hilltop castle, which served as a base for general Toyotomi Hidetoshi's 16th century invasion of Korea.

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.

The laid back port city of Takamatsu sits on the north coast of Shikoku, the smallest of Japan’s major islands, and is home to the beautifully designed Ritsurin Koen, one of Japan’s most famous historical gardens.
