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 semi-tropical island of Jeju is one of South Korea’s best kept secrets, a popular holiday destination for domestic travellers but little known outside of Asia. The craggy volcanic landscape, tangerine groves and beautiful beaches make this a lovely place to spend some time exploring.

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.

Manila is a sprawling, chaotic conglomeration of soaring skyscrapers, faded colonial facades and ramshackle slums, and it’s certainly not everyone’s cup of tea. But if you have the stamina and an inquisitive nature, there is plenty to be enjoyed in the Philippines’ boisterous capital.

The little island of Boracay is home to some of the world’s most beautiful beaches, including the aptly named White Beach. If sunbathing doesn’t appeal then there are plenty of more active pursuits on offer, including diving, kiteboarding and windsurfing, or you can take a trip out on the water on one of the pretty ‘paraw’ boats.

Puerto, as the locals call it, is the capital of Palawan province, founded by the Spanish in 1872. The city is the only major metropolis in this otherwise pristine and sparsely populated region, and the main attraction here is the spectacular Subterranean River National Park just to the north.

Kota Kinabalu is the gateway to the Malaysian state of Sabah and makes for an excellent base, whether you’re planning on scaling the commanding heights of Mount Kinabalu, exploring the islands and turquoise waters of Tunku Abdul Rahman Marine Park, or embarking on a trip into the jungle to encounter Borneo’s fantastic wildlife.

Muara is the main port of Brunei Darussalam, a tiny Islamic sultanate on the northern coast of Borneo. The sultan’s wealth is legendary, as is his sprawling 300-acre palace, although the capital city, Bandar Seri Begawan, is a surprisingly understated and likeable place, with an intriguing mix of Malay, Chinese and indigenous cultures.
