It is the world’s busiest transport hub by passenger numbers, a testament to its vital role in linking western Tokyo with central Tokyo and beyond.

Lines and services at Shinjuku Station

JR East lines at Shinjuku Station

JR East operates most of the trains from Shinjuku Station, making it a critical node on several major rail corridors. The JR East network includes:

• Yamanote Line — a circular route that connects major hubs such as Harajuku, Shinagawa, Akihabara, and Ikebukuro.
• Chuo Line — a key artery linking the western suburbs with central Tokyo, including rapid and local services.
• Chuo-Sobu Line — an urban through service running east–west and offering convenient access to several central districts.
• Shonan-Shinjuku Line — a through service weaving between the Shonan coast and central Tokyo, ideal for coastal or commuter trips.
• Saikyo Line — serving the western suburbs and the southern parts of Saitama, with connections to the Kawagoe area.

Passengers relying on Shinjuku Station frequently use these JR East lines to reach business districts, entertainment zones, and cultural sites across Tokyo and beyond. Timetables and platform assignments shift with the seasons and peak periods, so a quick check on arrival helps prevent delays.

Odakyu Odawara Line at Shinjuku Station

The Odakyu Odawara Line is a vital private railway service that departs from Shinjuku Station, taking travellers to destinations across western Tokyo and into Kanagawa Prefecture. The Odakyu network is particularly popular with visitors heading to Hakone, Enoshima, and the en route historic towns. The line’s express services offer a swift path to popular leisure spots and scenic areas, making the Shinjuku Station Odakyu corridor a favourite for day-trippers and weekend explorers.

Keio Line and its contribution to the Shinjuku interchange

Complementing the JR and Odakyu services, the Keio Line terminates at Keio Shinjuku Station, which sits adjacent to or within easy pedestrian reach of the main Shinjuku Station complex. The Keio network extends to Sagamihara and beyond, facilitating straightforward access to western Tokyo and the Kanto region. Though Keio operates its own station, modern passages connect the Keio facilities with Shinjuku’s JR hubs, enabling smooth transfers for those combining JR travel with private rail routes.

Access to Tokyo Metro and Toei Subway networks

Within the Shinjuku area, direct access to Tokyo Metro and Toei Subway networks is via nearby stations rather than directly through Shinjuku Station itself. The most notable connection point is Shinjuku-Sanchome, which sits a short walk from the JR interchange and provides access to multiple lines, including the Marunouchi Line and other subways. For travellers who plan to traverse Tokyo’s subway system, understanding these linked pathways saves time and reduces confusion when navigating the city’s underground maze.

The scale and layout of Shinjuku Station

Shinjuku Station’s scale is difficult to overstate. It comprises multiple interconnected halls, concourses, and underground passages that stretch for kilometres. The architecture reflects decades of expansion to accommodate surging passenger volumes while preserving efficiency for long-distance travellers and local commuters alike. A helpful way to approach Shinjuku Station is to think in terms of “East” and “West” precincts, each hosting a different set of lines and facilities, linked by an extensive system of corridors, escalators, and stairways.

East Exit, West Exit, and major transfer corridors

The East Exit area is a busy hub for JR East services and a gateway to central Shinjuku. In contrast, the West Exit region is more aligned with shopping and business districts, including connections to the private railways. The transfer corridors between these zones are often busy, mirroring Tokyo’s rhythm. To expedite travel, travellers should consult station maps upon arrival and follow the colour-coded signage that points toward the line or exit they need. The sheer density of corridors means that it is easy to take a wrong turn, so keeping a clear sense of direction helps to minimise time lost in transit.

Underground connections and crossings

One of Shinjuku Station’s defining features is its labyrinth of underground passages. These subterranean routes connect the various railway arms, enabling transfers without stepping into street level. When time-sensitive transfers are required, the underground network becomes a lifeline, especially during inclement weather or peak travel periods. A practical tip: download the official station map on a mobile device or pick up a physical leaflet at information desks to navigate quickly.
