Shinjuku is Tokyo in extremis — more neon, more people, more density, more variety than any other neighborhood in Japan. It rewards visitors who approach it in sections rather than trying to comprehend the whole at once.
Shinjuku Station: Getting Oriented
Shinjuku Station is the world's busiest — 3.5 million passengers per day through 50+ exits. The key orientating fact: the west side (Nishi-guchi) has the skyscrapers; the east side (Higashi-guchi) has the entertainment, shopping, and nightlife. Most visitors want the east side. The South Exit (Minami-guchi) leads to Takashimaya Times Square and the bus terminal. If you get lost, look for the "Central East" or "East" exit signs and walk through to daylight — the street level makes sense once you're aboveground.
West Shinjuku: Power and Height
The skyscraper district immediately west of the station houses Tokyo Metropolitan Government Building (free observation deck, 45th floor, open until 10:30pm — the best free view in Tokyo), the Park Hyatt Hotel (Lost in Translation bar, 51st floor, worth a drink at ¥1,500), and dozens of corporate towers that create one of Asia's most impressive urban canyons. Best experienced at dusk when the towers light up.
East Shinjuku: The Entertainment District
Kabukicho: Japan's largest entertainment district — love hotels, host clubs, izakaya, pachinko, ramen, and karaoke stacked in dozens of blocks around Robot Restaurant's former location. The atmosphere is electric and harmless by global entertainment district standards. Golden Gai: 200+ tiny bars in six interconnected alleys, each holding 5–10 people. Themed bars (horror, jazz, cinema, cats), cheap drinks, and conversation with strangers. The most intimate and atmospheric nightlife in Tokyo. Omoide Yokocho (Memory Lane): A narrow alley of yakitori and izakaya stalls directly under the railway tracks, smoking with charcoal. ¥500 for a skewer and beer while the train rumbles overhead.
Shinjuku Gyoen National Garden
A 10-minute walk from the station: Shinjuku Gyoen (¥500) is Tokyo's finest park — 58 hectares combining French formal garden, English landscape garden, and traditional Japanese garden in one space. The cherry blossom season here (late March–early April) is exceptional and more manageable than Ueno Park crowds. The greenhouse contains tropical plants including an enormous cycad. Open 9am–4:30pm, closed Mondays.
Shopping in Shinjuku
Isetan department store's basement food hall (depachika) is the best in Japan. Takashimaya Times Square has 14 floors of retail. Disk Union in the back streets east of the station has the finest selection of used vinyl in Tokyo. The Yodobashi Camera megastore near the station west exit is the best electronics shopping in Japan — tax-free for tourists and stocked with everything.
