Are there any small mountains in Japan to climb?

I will be in japan for 2 weeks at the end of April/ beginning of May and I am looking for a small mountain to climb.

As I am with someone who is less experienced at walking long distance I am wanting to find a small mountain that can be done in a day which isn't dangerous. I've seen there is places in Daisetsuzan National Park that have lifts so I thought maybe hike up and lift down but I have a feeling this isn't going to be genuine enough?

Any suggestions?
