I went there several times, alone, in couple, in family and with friends, and it always has been a really good experience.
It's a very nice walk, and the view from the top is beautiful.
Perfect spot for photos obviously.
If you dare explore a bit off the paths, you can find a lot of cool places as well, like mini temples and quieter places in nature.
I definitely recommend going, but preferably early in the morning, before it gets insanely crowded.
The walk from the station to the shrines is cool as well, you can sample different kind of street food.
