South east shinjuku to Subaru building

[Miemie]

Hi, I'll be staying at the South east side of the station.. nearest exit should be the new South gate? If I need to get to the west side to the Subaru building.. how shall I walk pass the station? 

[Japan Station]

From the New South exit you can walk around the station on the west side. Here is a map:
