I will arrive Tokyo from Osaka via Willer bus and the final stop will be at Shinjuku West exit. What is a west exit? If this is a train exit, is this one railway exit only? I'm kinda confused with all the trains -- example in Osaka that there are diff train operators but all called Namba. So if this is Shinjuku exit, what exit of what railway?
The exact stop of the bus will be in Shinjuku Sumitomo Bldg, what hotels are near in this station?
