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, 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.

Steam rises over the spa town of Beppu, home to numerous onsen (hot springs) and the surreal red waters of the macabre-sounding ‘blood pond hell’. Beppu is also close to Mount Aso, the largest active volcano in Japan, and the ancient temples of the Kunisaki Peninsula.

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.

Fukuoka is the largest city on the southern island of Kyushu, and has long been an important centre for trade due to its proximity to the Asian mainland, closer to Seoul than it is to Tokyo. It’s a friendly, sunny place, and the city was created by a merger of two towns: Fukuoka, the old castle town, and Hakata, the former merchant district.

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.

If you need respite from the urban sprawl seek out Osaka Castle and the surrounding Nishinomaru Garden, a particularly pretty spot during the cherry blossom season.

Keelung is a fairly unremarkable port city close to Taipei, Taiwan’s capital.

Hong Kong is a striking mix of ancient and modern, Chinese and British, and there is a lot more to the city than just skyscrapers and high finance. It's also a fantastic destination for foodies, a melting pot of culinary influences from around Asia and beyond.

Saigon, as it was known then, was the capital of the South during the Vietnam War, and American-style capitalism has been embraced more enthusiastically here than in the North, with a clutch of shining skyscrapers standing as testament to Vietnam’s surging economic growth.
