Interesting article from the Japan Times from Jan 2015 called "In Kawabata's footsteps to Snow Country". In it, the author recounts the modern day experience of coming through the long tunnel from the Kanto Plains, under the Tanigawa Range and finding yourself in a completely different world covered in snow. The description of this experience also happens to be the first line of the Yasunari Kawabata's "Snow Country" novel.
The author then goes on to stay in Takahan Ryokan , enjoys the amazing dinner served there, and searches the town for traces of the geisha Komako.
Although it is not about skiing in Yuzawa (GALA Yuzawa gets a brief mention), it is a fun read and gives a nice overview of the town. It also notes that it "house the biggest ski resort accessible for day trips from the capital" Tokyo.
