10 day interactive trip?

Hi there, im travelling through japan for 10 days from the 28th of november. I arrive in osaka, and plan on spending 2 days in osaka, 4 days in kyoto, then 4 days in tokyo.
The problem lies with, i am travelling with my girlfriend, and she is not a sight seeing type of girl, she can handle a little bit of it, but not alot. She likes interactive sort of sightseeing....kinda of like lets say dressing up as a ninja and going through the ninja museum and house in iga ueno (unfortunately not on at this time of year). So i was wondering what sort of things we could do to keep her entertained,
One thing i might do is, spend a night in a temple at the grave yards in koya-san,

Any help is much appreciated. thankyou

thanks guys, some of the things looks very kiddy...but thanks anyway, we'll see how we go. Has anyone done the, dress in samurai armour and mess around + photo shoot thing in tokyo? looks kinda cool, but a little expensive.
Keep the options coming if anyone else knows any, thanks
