Nice and relatively easy 30 min hike from Hirayu Onsen Bus Terminal to the Waterfall. Best to go before 10:30 am as the sun behind the Waterfall will be very glaring if you want to have a nice photo shoot of the Waterfall. After 11:30 am should be better or later part of the day.

You can park your car at the parking near the entrance of Hirayu Ski Area. Then take a 750m-walk around 15 mins to the waterfall.
The day I went it was snowy and beautiful.
