Getting There
Shinjuku is served by the JR Yamanote, Chuo and Sobu lines, the Keio and Odakyu lines, the Marunouchi subway, and the Toei Shinjuku and Oedo lines; no station in the world handles more passengers. The Narita Express runs direct from Narita in about 90 minutes. From Haneda the standard route is the Keikyu line to Shinagawa and the JR Yamanote from there, about 40 minutes.

Best Time to Visit
Cherry blossom season (late March to early April) transforms Shinjuku Gyoen into one of Tokyo's most stunning sights. Summer (July–August) brings matsuri festivals and vibrant street energy but high humidity. Autumn foliage in the Gyoen (November) is underrated. Year-round, the nightlife peaks on Friday and Saturday evenings.

Local Tip
Shinjuku Station's west exit underground plaza (『Nishi-guchi Chikashitsu』) was historically a gathering point for homeless communities and countercultural figures — a complex social history worth reading about. For navigation, use the 『My Shinjuku』 app or follow the color-coded floor maps at each major exit. If you're heading to Golden Gai, the east exit path via Studio Alta building is the most direct.
📖
What the Name Means
The name means the new post town. In 1698, the stretch between Nihonbashi and Takaido being judged too long, a new station was opened on the Koshu highway. The land had belonged to the Naito family, lords of Takato in Shinano, so it was called Naito-Shinjuku; in time only Shinjuku remained.
