If you want fewer crowds, go at this time; if you want beautiful scenery, you have to be in the crowds. Even without the autumn leaves turning red, the view of Lake Chuzenji is indeed spectacular. The cable car ride from start to finish takes less than 3 minutes. If it's too crowded and you can't get a window seat, I suggest waiting until after work, but make sure to catch the bus.
