Echigo-Yuzawa Station, the nearest station to Echigo-Yuzawa Onsen, is just 70 minutes from Tokyo by Shinkansen. Besides its easy access from Tokyo, the place is known as an area that receives some of Japan’s heaviest snowfalls, and it’s amazing to see how much snow piles up. If you visit the town in winter, be sure to get a combo ticket that can be used at Yuzawa Kogen Ski Resort to take advantage of the winter activities and onsen facilities.
This makes Echigo-Yuzawa an easy "Snow Country" to visit. There are several ski resorts enveloping the town, creating a destination where you can take in all sorts of winter activities over and above skiing and snowboarding.
