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.

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.

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.

Naha is the capital of Okinawa prefecture, a subtropical region of southern Japan with its own distinct culture. The city is a bustling commercial centre despite being flattened during the Second World War, and the architectural highlight is the elegant Shuri Castle, a UNESCO World Heritage Site.

Keelung is a fairly unremarkable port city close to Taipei, Taiwan’s capital. Taipei draws on an interesting mix of Chinese, Japanese and Western influences, and is home to attractive temples, a burgeoning street food scene and Taipei 101, which was the world's tallest building until it was eclipsed by Dubai's Burj Khalifa in 2010.

Kaohsiung is Taiwan’s second largest city and one of the world’s largest container ports, situated on the south west coast of the island. Formerly a rather grim industrial centre, the city has been transformed in recent years, with new parks, cafés, galleries and museums popping up all over the place.

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.

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.

Singapore’s heritage as an important trading post means that there is a real cultural mix, with four official languages: English, Chinese, Malay and Tamil. Step away from the gleaming towers and you’ll find yourself transported into another world amongst the intoxicating streets of Chinatown and Little India.

Malaysia’s capital is a hot and humid cultural melting pot, defined by its distinctive Malay, Chinese and Indian communities. The dazzling Petronas Towers are KL’s most recognisable landmark, while at street level you’ll find temples and mosques, elegant colonial buildings and bustling markets.

Indonesia’s capital is noisy, chaotic and choked with some of the worst traffic in Asia, a sprawling megacity that’s home to over 10 million people. If you can get past all of that then Jakarta has plenty to offer, with the country’s best museums and restaurants, an atmospheric old harbour and a rich mix of cultures from all over the Indonesian archipelago.

The sweltering city of Semarang, on the north coast of Java, is an intriguing mish-mash of Chinese, Islamic and Dutch colonial influences. We recommend escaping the heat with a trip up into the mountains to visit a coffee plantation, or joining an excursion to the extraordinary temple complex at Borobudur.

Surabaya, situated on the northeast coast of Java, is Indonesia’s second largest city and the place where the country’s struggle for independence began. The warren-like Arab Quarter is worth exploring, though many visitors use the city as a base for visiting nearby Mount Bromo.

Celukan Bawang is the main port in northern Bali, with quite a different feel to the more touristy parts of the island. Here you can see the magnificent Bugis schooners of Sulawesi, and nearby sights include the former Balinese capital of Singaraja, the wildlife sanctuary of West Bali National Park and the black sand Lovina Beach.

Quieter and less developed than neighbouring Bali, the island of Lombok is an appealing alternative. To the north, the landscape is dominated by the huge crater of Gunung Rinjani, while the south and west coasts are home to some stunning beaches.
