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.

Osaka, Japan’s third largest city, is a pulsating commercial hub, famous for its food, and the cityscape rivals Tokyo for neon-lit futurism. 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.

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.

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.

Booming Shanghai has long been China’s most outward-looking, cosmopolitan city, as evidenced by the fascinating mixture of European and Asian architecture. The Bund, a riverfront promenade flanked by grand colonial era buildings, is the city's most famous thoroughfare, while the Pudong financial district lights up the city skyline at night with its futuristic towers.

Xiamen is one of China’s most liveable cities, perched on an island next to the Taiwan Strait. One of the most popular activities here is a trip across to the much smaller and traffic-free island of Gulangyu, renowned for its beaches, gardens and crumbling colonial architecture built by European traders.
