There are many exits in Shinjuku Station. This is a photo of JR Shinjuku South Gate, taken from outside. Once you leave the exit, move on to the next picture.

As you leave the station, you will see a big crossing ahead of you. Cross to the other side (watch out for traffic).  Proceed to the next photo.

The other side is also Shinjuku Station plus a bus terminal. Don't go inside, and simply take a left and walk alongside the building as indicated by the arrow.

When you come to this spot, take a right. There should be a roof overhead at this point. Proceed to the next photo.

Keep going straight ahead. On your left is Miraina Tower office building.

As you walk, you will see another JR exit on your right. This is called Miraina Tower gate and may be more convenient for some people, especially if you use Saikyo Line. Keep this exit on your right and keep walking in the direction of the arrow.

You will soon see a big building with Takashimaya in red letters. This is the department store. With Takashimaya on your left, keep walking ahead on the path outside the building.

You're almost there. As you come to the end of the Takashimaya building, you'll see another building ahead of you, where we are. Cross the bridge and go inside the Nitori home furnishings store. Take the elevator / escalator up to the 6th floor, and you've reached our bookstore!
