How To Go From Shinjuku Station To The Hyatt Regency Tokyo (Completely Underground!)

If you’ve ever looked at a map of Shinjuku Station and then tried to actually walk somewhere from it… you already know the problem. It’s huge, confusing, and full of exits that don’t seem to point where you think they should.

When we stayed at the Hyatt Regency Tokyo, I went down a bit of a rabbit hole trying to figure out the “best” way to get there. Turns out, there isn’t just one way—and depending on your tolerance for crowds, stairs, and getting a little lost, your definition of “best” might be different than mine.

Here’s a simple breakdown to help you get your bearings and walk from Shinjuku Station in Tokyo to the Hyatt Regency Tokyo completely underground (and avoid wandering around Shinjuku for 45 minutes like I may or may not have done the first time 😀 )

What Is Shinjuku Station

Shinjuku Station isn’t just a train station – it’s basically a small city. It’s widely considered the busiest train station in the world, with millions of passengers passing through every day, and over 1 billion passengers per year.

You’ve got JR lines, multiple private railways, and several subway lines all mashed together, plus underground shopping areas, restaurants, and endless corridors. One source I saw said that it had over 200 exits, each labeled with letters and numbers like A7, C4, etc.

The key thing to know: which exit you use matters way more than which train you arrive on. Two people can arrive at the same station and end up a 15–20 minute walk apart just based on the exit they choose.

For the Hyatt Regency Tokyo, the magic exit is C4.

How To Go From Shinjuku Station To The Hyatt Regency Tokyo

There are a few different ways to get from Tokyo Shinjuku Station to the Hyatt Regency Tokyo, and which one you pick really depends on your situation:

1. Underground tunnels (what this guide focuses on)
This is great if it’s raining, hot, or cold. You can stay almost entirely underground and pop up right near the hotel at Exit C4. Downsides: it’s easy to get turned around, and there are a decent number of escalators and level changes. This might be tricky to do if you are unfamiliar with the area, don’t like trying to navigate, or have lots of luggage.

2. Above-ground walk
Probably the simplest mentally. Just head west toward the skyscraper district near the Tokyo Metropolitan Government Building and walk about 15–20 minutes. This is a good option if you want fresh air or are tired of navigating underground mazes. Google Maps works pretty well for this, but if it’s dark, it can be a bit confusing to figure out your landmarks to make sure you’re going in the right direction.

3. Taxi
If you’ve got a lot of luggage or just don’t want to deal with directions, this is the easiest option. It’s a short ride (usually under 10 minutes depending on traffic). Not super cheap, but not crazy expensive either for the convenience.

4. Hotel shuttle bus
The Hyatt Regency Tokyo runs a free shuttle to and from Shinjuku Station. This is a great option if you time it right – especially with luggage. The downside is you have to find the pickup spot and match the schedule.

5. Toei Oedo Line (one stop)
You can take the Toei Oedo Line one stop from Shinjuku to Tochomae Station, which is right by the hotel. Honestly, by the time you walk down to the platform and back up, it’s not always faster than just walking, but it’s an option.

6. Bus
There are local buses that run through the area, but unless you’re already familiar with Tokyo buses, this is probably more hassle than it’s worth for such a short distance.

Quick takeaway:

• Want easiest? → Taxi or shuttle
• Want simplest navigation? → Walk above ground
• Want weather-proof? → Underground route (below)

Step By Step Instructions To Go From Shinjuku Station To The Hyatt Regency Tokyo Via Underground Tunnels

I’m not going to say going through the subway / metro tunnel is the BEST way to go from Shinjuku Station to the Hyatt Regency, especially if you’re unfamiliar with the area, have lots of luggage and/or don’t like going through underground tunnels. For me, as someone who really enjoys maps, navigation, and puzzles it was great.

So how do you go from Shinjuku Station to the Hyatt Regency through the Shinjuku Station complex?

The nice thing is that all of the exits in the Tokyo subway are IDd with a letter and a number. This makes it much easier to find the right exit than in other subway systems. The first thing to realize is that the Hyatt Regency is at exit C4.

But you are about a 15 minute walk from the center of Shinjuku Station to the Hyatt Regency Tokyo and so the signs don’t show exit C4 for awhile. This is what you should be looking for

• Tokyo Oedo Line
• Tokyo Metro Government / Chuo Park
• Exit A4
• Exit A7
• Exit C4

Here is how to do it with pictures

First, you’ll exit the fare area. If you have the option, choose the westernmost gate. For the JR lines, choose “West Gate” and then turn left

Follow signs for the Keio Line, but don’t go through any fare gates. Once you see the fare gates below, go along to the right, follow the signs to the right for the “Keio New Line Concourse”.

You’ll go down a hallway, passing what I believe is the Shinjuku bus stop area on your right. Once you pass the area with the bus stops outside, you’ll turn left and start going down a long hallway. There are a series of moving walkways on your right

After you go through several moving walkways, you’ll reach the area below, which is outside but covered. Go down the escalator following the signs for the Toei Oedo Line Tochomae Station.

Once back underground, follow signs for A4 by going to the right.

You’ll go down another level, still following signs for the A4 exit and Tochomae Station.

Once you reach the fare gates for the Oedo Line Tochomae Station, do not go through them. Instead, continue following signs for A7.

The A7 exit also has entries for the C and E exits, which is eventually the one you want.

Continue following signs for A7 and then C4.  Exit C4 from Shinjuku Station is the one that goes to the Hyatt Regency Tokyo. As you go towards C4, you’ll go up a double level escalator. Then, you’ll reach Exit C4, which is up a staircase, with signs for the Hyatt Regency Tokyo.

Go up the steps or escalator

You’ll come out to a semi-open air plaza, with a 7-11 on your right. If you are checking in for the first time or want to go to the main lobby, you might turn to your left, walk outside and then turn left and up a flight of stairs to the main entrance.

Otherwise you can go up the steps to the left of the 7-11 and turn left, where you’ll see the door below, with a Hyatt Regency sign.

You’ll be on the 1st floor, which is 1 floor below the main lobby (which is on the 2nd floor). You can take an escalator up to the 2nd floor or, if you have already checked in, take an elevator to your room.

The Bottom Line

Getting from Shinjuku Station to the Hyatt Regency Tokyo isn’t hard… it’s just a little overwhelming the first time.

If you like a bit of a challenge (or just hate bad weather), the underground route to Exit C4 works great once you know what you’re doing. If not, walking above ground or grabbing a taxi is totally reasonable and might save you some frustration.

Either way, once you’ve done it once, it gets way easier the next time, AND you’ll feel like a Shinjuku navigation pro.
