The Shinjuku area is one of Tokyo's great urban centres, radiating out from Shinjuku Station — the busiest railway station in the world by passenger numbers. JR lines, the Keio Line, the Odakyu Line and several subway lines all serve the station, and the directly connected Busta Shinjuku terminal sends buses to airports and destinations across Japan, making it ideal for expatriates who commute or travel frequently. The Tokyo Metropolitan Government Building in Nishi-Shinjuku has observatories 202 metres above ground with sweeping views of the city — a popular attraction that is free to visit. Shinjuku Gyoen National Garden, an oasis in the city, is beautiful in every season and becomes a family gathering place during the cherry blossom and autumn foliage seasons. Department stores and restaurants such as Isetan Shinjuku and Takashimaya Shinjuku mean that almost everything you need for daily life can be found around the station. The area also takes in Shinjuku Central Park and the Kabukicho entertainment district; Shinjuku City is one of the Tokyo wards with the largest foreign resident populations, and multilingual service is widely available. Many shopping complexes are directly connected to or adjacent to the station, so shopping stays comfortable even in the rain. Restaurants from around the world gather here, making it easy to find the flavours of home. This is a convenient, endlessly stimulating area where the food and culture of the whole world are within reach.
