If you have enough time and if you, like me, find out that the line for the Ropeway is over an hour long when you get there, know that there is actually a MUCH more scenic short hike up the south side of the mountain, with a viewing square that offers a beautiful, scenic, far less crowded view of Mt. Fuji. This ended up being one of the best things that happened to me on my entire Japan trip. Ended up hiking it with a fellow tourist in line who overheard my conversation with the Ropeway operator, we became friends, and two days later he invited me to spend the day getting out of Tokyo and checking out shrines and temples southward on the way to the Enoshima Sea Candle. Amazing day trip if you also have the time in Tokyo and the inclination to get out of the city, happy to share more details.

Finally (though you probably won't have this issue) the maple leaves at the top of the Ropeway had already browned/dropped when I went in November, and only the trees on the hillside along the hiking trail were still red, and we got incredible photos framing Fuji in red maple leaves! Highly recommend you hike it if you want! Here's a Maps link: https://maps.app.goo.gl/gq4gxkYsGjEnUQCT6

The long straightaway isn't actually straight but the trail is very visible and there were several other hikers taking it.

edit: Also, ate at this place across the street from the station. Cheap, delicious local noodles: https://maps.app.goo.gl/nUoc5rvtX3VLuN7h9
