Starting from Nagoya, you don't need to worry about being unfamiliar with the transportation. For those who want to explore Kamikochi, there's no need to research routes and transfers; you can focus on your sightseeing. The guides are also familiar with Kamikochi, making it suitable for first-time visitors.
The scenery was wonderful, and it wasn't too crowded, so we were able to sightsee at our own pace. I appreciate that the cable car operates year-round.
Pity it was a cloudy/rainy day. Didn’t get to see mount fuji. Nevertheless, kudos to the guide/driver - Bruce, who brought us around, safely and efficiently. It would be better if more time is catered for the first stop, Arakurayama Sengen Park.
