From the hectic multi-road crossing at Shibuya (made famous in Lost in Translation) to the peaceful tree-filled gardens at Meiji-jingu, the city's key sights are varied and mesmerising. Watch the fashion-obsessed teens every Sunday in Shibuya, step back in time in Asakusa's crowded street stalls, and revel in the neon lit view from the top of Roppongi's Tokyo Tower.

Unlike other cities of its size and significance, however, Tokyo lacks a definable centre or landmark. Instead the city is divided into separate and wholly distinct neighbourhoods, each with their own secrets to discover. The best way to navigate these mini-cities is on the excellent Metro system, specifically the Yamanote Line, a commuter train loop which passes through many of Tokyo's major stations.

But as with all of Japan, the key to discovering the true Tokyo lies in the details. Simply wandering though an area reveals the secrets that make this city so unique.

With no street names, however, finding exactly where a building is in Tokyo can be fiendishly difficult. Buying a detailed bilingual map will certainly help, and with so little crime to solve, the police in their boxes (called koban) on practically every corner are both plentiful and experienced in redirecting the lost traveller.

Lastly, study the large and detailed maps on display at every Metro station. These clearly show which exit is needed, in English.

The Japanese National Tourist Organisation (JNTO) runs two Tourist Information Centres (TIC) in Tokyo, one in Narita Airport and one in central Tokyo. They both offer a wealth of information to the new arrival; detailed maps, guides to Japanese culture and hotel information. English speaking staff can book your accommodation commission free and are a fantastic source of local knowledge.
