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.

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.

The port of Chan May is close to a number of central Vietnam's star attractions. Just to the north lies Hue and its crumbling Imperial Citadel, a UNESCO World Heritage Site, while to the south is the city of Da Nang, a major US airbase during the Vietnam War, and pretty Hoi An, a dreamy tropical haze of teetering merchant houses, bustling markets and Chinese temples.

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.

The once sleepy backwater of Kompong Som, renamed after the former king Norodom Sihanouk, is the rising star of the Cambodian coast’s burgeoning tourist industry. Here you’ll find beautiful sandy beaches and a string of laid back islands that are still largely undeveloped.

Thailand’s sprawling capital is an assault on the senses, an invigorating blend of tradition and modernity. Soaring skyscrapers, air-conditioned shopping malls and an efficient public transport system combine with shimmering golden temples, ancient palaces, floating markets and at times gridlocked rush hour traffic.

Attracting everyone from budget backpackers to ostentatious oligarchs, Koh Samui is one of Thailand’s most popular islands. It’s no surprise, given the truly stunning beaches, but the more developed areas such as Chaweng have lost a lot of their charm, so head for the quieter south and west if you can.

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.

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.

More of a large town than a city, Darwin is less about what’s contained within the city limits and more about the huge expanse of wild landscape that’s outside it. Closer to Jakarta than Sydney, the city really does feel remote in its tropical perch.

Thursday Island is one of the Torres Strait Islands, situated to the north of Cape York. Proximity to Papua New Guinea makes for an interesting cultural mix, and the island has a fascinating military history. Be aware that swimming off the beautiful beaches is not recommended due to the presence of crocodiles and marine stingers.

Cairns is a buzzing tourist hub, gateway to the Great Barrier Reef and the Daintree Rainforest. A snorkelling trip out to the reef is the most obvious excursion to take here, but other options include riding the Skyrail cableway over the rainforest canopy or swimming in the croc-free saltwater lagoon.

Lautoka is Fiji’s second largest city, known as the ‘Sugar City’ due to its important role in the local sugarcane industry. The waterfront area is pleasant enough, but we’d recommend using Lautoka as a jumping off point to visit some of the smaller surrounding islands, or the forests and waterfalls of the interior.

Suva is Fiji’s bustling capital, situated on the southeast coast of Viti Levu on a fine natural harbour. This is one of the more attractive port cities in the South Pacific, with a handsome core of colonial buildings that hark back to the days when Fiji was an outpost of the British Empire. The colourful wooden buildings of Cumming Street are particularly pretty.

Apia is the capital of Samoa, situated on the north coast of the island of Upolu. Highlights include the colourful markets and Robert Louis Stevenson's former house, now a museum, though you may just want to use the city as a jumping off point for the beautiful beaches located further along the coast.

The little fishing town of Pago Pago is the capital of American Samoa, a rarely visited but utterly enchanting archipelago in the South Pacific. Pago Pago sits on a beautiful natural bay on the island of Tutuila, a lush and mountainous place where Polynesian traditions remain strong.

The beaches and over-water bungalows are particularly popular with honeymooners, and the clear waters of the lagoon are perfect for snorkelling.

Papeete is the capital of French Polynesia, situated on the northwest coast of Tahiti. The port is not the most magical spot, so we advise venturing forth to luxuriate in the turquoise lagoons, relax on the white sand beaches fringed with palm trees, and explore the rugged mountain peaks.

Hilo is located on the east coast of Hawaii’s Big Island, a lush region of verdant rainforests, botanical gardens and gushing waterfalls. In the 1800s this was an important centre for the sugar industry, and the surviving plantation-era architecture gives downtown Hilo its uniquely quaint appearance.

The Kailua-Kona region, on the west coast of Hawaii’s Big Island, is known for its idyllic beaches and fantastic climate, notably sunnier and drier than the eastern side of the island. This is where you’ll find some of the island’s top resorts, and the surrounding waters are home to turtles, manta rays, dolphins and humpback whales.
