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.

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.

Ishigaki is the most developed of the Yaeyama islands, an idyllic tropical archipelago located closer to Taiwan than mainland Japan. The offshore coral reefs make this a popular spot for diving and snorkelling, while the jungle interior offers some great hiking opportunities.

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.

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.

Wander along the perfumed streets of Hanoi’s atmospheric Old Quarter and you could almost forgive yourself for thinking you’d travelled back in time, were it not for the beeping, buzzing morass of motorcycles zipping past.

Nha Trang is Vietnam’s premier beach destination, on a stunning bay dotted with idyllic islands. The main attraction is the laid back seaside atmosphere, but there are also a few noteworthy cultural sites, including the ancient Po Nagar Cham Towers, which were built between the 7th and 12th centuries.

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.
