Anyone know this place?

I visited Japan last year, and this picture was taken during a bus trip from Tokyo. All I can remember is, in front of me there was a convenient store that sells sakuramochi, an ice cream vendor, and on the top floor of the store (using elevator) there's a place where we (groups) can eat some sort of steamboat or sukiyaki on tatami floor.
I think it's a tourist spot because I noticed there were more busses on the parking lot.

Does anyone recognize the place?

That looks like the crater lake in Hakone.

We took an awesome lake tour followed by a gondola climb to the top of a mountain. Beautiful scenery.

I think it is the kawaguchiko lake.

Today it snows in Kawaguchiko, so you can find the snowy lake tommorow (JPN time).
