According to NHK Net News Web Easy, around the Lake Chuzenji, Nikko, Tochigi has been lit up for an enjoyable beautiful night view in order to attract many tourists for sightseeing after the autumn leaves season gone.
At the famous kegon no taki (Kegon waterfall), the lights shine on the waterfall, which falls 97 meters down, at the dark night and the water looks like the white light. At Chuzenji, the red building of the temple looks like floating mysteriously.
The people came form Tokyo said 「I do not come to the temple much at the night but I thought it was beautiful and splendid.」
The illumination is to be on from 4.30 pm til 7 pm every day until 23rd of this month. We can enjoy the view from the lake on a boat at Saturdays night and Sundays night.

I have been to Nikko in June 2018. The famous temple and the waterfall are a must visit. It must be so magnificent night view at the temple and be a magical moment to see the white light on the waterfall that I can imagine. Oh I really wish I was there to see it. The below is the Kegon no taki at the summer of 2018.
