Snow town Yeti

Hi,

I will be traveling to snow town yeti with my partner on 30 Jan 2016.

I have a few queries.
1. Is there a direct bus service from Shinjuku and if yes, where is the bus stop located at Shinjuku as well as Yeti?
2. Can foreigners buy this bus ticket?
3. Can we book online? and is it an email confirmation of booking?

Thanks in advance.
