Quick answer: Shinjuku Station is recorded by Guinness World Records as the busiest railway station in the world, with about 2.7 million passengers a day in 2022. The trick is to choose your exit before you leave the platform: East for Kabukicho, West for the skyscrapers and Tokyo Metropolitan Government Building, South and New South for buses and shopping. If you pick the wrong side, a ground-level passage connects east and west.

Shinjuku Station can look intimidating at first glance, with crowds, color-coded signs and corridors that seem to go on forever. The good news is that it follows a logic, and a few simple habits turn it into a fun place to explore. Five railway and subway operators share the complex, dozens of exits lead to different neighborhoods, and signs in English help along the way. This guide explains the layout, the main exits, how to cross between sides, how to transfer between lines and how to travel with luggage.

What makes Shinjuku Station so big

Shinjuku Station opened on March 1, 1885, and grew with the city around it. Today it is recorded by Guinness World Records as the world's busiest railway station, including subways, with an average of 2,704,703 passengers per day in 2022. Other counts that combine every operator's figures are higher, and Wikipedia gives about 3.59 million a day for 2018, so the number you see depends on the year and how it is measured.

Five operators serve the complex: JR East, Keio, Odakyu, Tokyo Metro and Toei. Lines include the JR Yamanote, Chuo, Chuo-Sobu, Shonan-Shinjuku and Saikyo lines, the Odakyu Odawara Line, the Keio Line and Keio New Line, the Toei Shinjuku and Oedo lines, and the Tokyo Metro Marunouchi Line. Reference sources count the complex as having well over 200 exits.

This size explains why the station feels like a small city. Department stores, shopping arcades, restaurants and bus terminals all connect to it. Instead of trying to understand the whole thing, the best approach is to understand the one small part you need.

Choose your exit before you leave the platform

The most valuable habit is to decide on your destination first and then look for the exit name. Line signs use the color and letter of each line, and exit signs name the exit, so look up for the exit name rather than only following the crowd.

The East Exit leads toward Kabukicho (a neon entertainment district with theaters, restaurants and nightlife), Golden Gai and the Shinjuku-dori shopping streets. The West Exit leads to the skyscraper district and the Tokyo Metropolitan Government Building, often called Tocho, as well as the Odakyu line. Japan-guide.com notes that redevelopment near the West Exit is changing pedestrian routes, so follow current signs.

The South Exit leads toward Lumine department stores and the Southern Terrace promenade. The New South Exit and Koshu-Kaido Exit lead toward Busta Shinjuku, the expressway bus terminal that opened in April 2016, along with NEWoMan, Takashimaya Times Square and Shinjuku Gyoen. The Miraina Tower Exit also leads toward Busta and NEWoMan.

Understand the gates and the floors

Shinjuku's JR gates are spread across several floors, which is part of the confusion. The JR side alone has about ten gate areas, named for the direction they serve, such as East, Central East, West, Central West, South, New South, Koshu-Kaido and Miraina Tower. They sit on different levels, so the gate you need may be up or down a floor from where you arrive. The station maps posted on the concourse show the current layout.

Knowing the floor lets you head straight to the right level. If you plan to meet someone, name the exit and the gate, such as "New South Gate" or "East Exit", rather than just "Shinjuku Station". It saves a lot of waiting around in the wrong place.

Walking time between gates can be a few minutes, even within the same side. Leave extra time for transfers and meetings, particularly at busy hours when corridors fill with commuters.

Crossing between east and west without getting lost

One of the most common mistakes is exiting on the wrong side. The fix is simple. A passage called the East-West Free Passage, which opened in 2020, lets people cross between the east and west sides without passing through ticket gates, so you can switch sides without paying or tapping again.

Underground passages also link areas. Long shopping streets run beneath the streets toward Shinjuku-sanchome in the east and toward the skyscrapers in the west. Walking to the Tokyo Metropolitan Government Building through the underground passage takes a good ten minutes or more, and a popular alternative is to take the Toei Oedo Line one stop to Tochomae.

If you ever feel lost, go up to street level and orient yourself by landmarks. Many visitors use the large 3D cat billboard on the east side, Busta Shinjuku and the new buildings on the south side, and the Tocho towers on the west side. Asking a staff member at a station office is also perfectly acceptable, and staff are used to helping visitors.

Transfers between lines take longer than they look

A transfer on a map may seem short, but in Shinjuku it can involve long corridors and stairs. As a rough guide, changing between two JR lines is usually quicker than changing between JR and a private or subway line, which can involve a longer walk and several level changes. Exact times vary with the platform, the crowds and your luggage, so allow generous time and check your route app.

When using a journey-planning app, choose one that names the exit or gate so you can plan the walk. Allow extra time for reserved trains or highway buses, and aim to arrive at your gate with a comfortable buffer. This is a good habit for any big station in Japan.

It also helps to remember that platforms and lines are organized by operator. If you are changing from JR to a private line such as Odakyu or Keio, you will usually exit the JR gates and enter the private line's gates, so keep your IC card or ticket ready.

Traveling with luggage and getting step-free access

Large suitcases can be tricky in a station with so many stairs. Follow the elevator symbols instead of the crowd, because the main flow of people often leads to stairs. Elevators serve many parts of the station, and the station maps show where they are, which makes it worth planning your route if you have bags, a stroller or limited mobility.

Coin lockers are available around the station. Prices usually run from several hundred yen to over a thousand yen a day depending on size, and large lockers can fill up at busy times, so arriving early or using a staffed luggage service is wise. Prices and availability change, so look at the posted rates.

Many visitors also use hotel luggage services or send bags ahead. If you are heading to a bus or airport train, allow additional time to find the right platform with bags in tow.

Nearby places worth the walk

One reward of learning the station is how close great places are. From the East Exit, Kabukicho is a neon entertainment district full of theaters, restaurants, cinemas and nightlife. Checking venue details in advance and sticking to the main streets makes for an easy, enjoyable evening.

From the West Exit, the skyscraper district and the Tokyo Metropolitan Government Building are close. Its twin towers are known for observation decks that offer broad views of the city. Shinjuku Gyoen, a large garden, is reached via the New South Exit side.

Omoide Yokocho, a network of tiny eateries along the tracks, sits near the northwest side of the station. Its narrow lanes and lanterns are a favorite for evening meals and photography, so keep voices low and ask before photographing people.

A simple routine for your first visit

A short routine makes the station much easier. Before you arrive, decide the exit and the gate you need. When you step off the train, look for the exit sign and follow it. If you need to cross sides, use the East-West Free Passage. If you are transferring, allow extra time and follow the color and letter of the next line.

Give yourself time on the first visit. Wander through a department store basement, stop for coffee and let the rhythm of the station sink in. Most visitors find that after one or two trips, the layout starts to feel familiar.

Finally, check current signs and station notices, because redevelopment is ongoing and routes can change. With a little preparation, the world's busiest station becomes a convenient doorway to one of Tokyo's liveliest districts.
