Remove Osaka, Nara, Kyoto and Studio Ghibli.
Travelling with 4 kids before 12 and a elder you need to really make it more relaxing. Shinkansen or fly to Osaka and then moving hotels like this as a DIY trip will tire out the participants before they get to the fun bits. This itinerary is a package tour imo.
Instead, you can go visit places like Odaiba, Akihabara, skip Tsukiji if you are worried abt tracking the little ones as the place is a bit messy and crowded.
I would instead recommend going to say Enoshima or a side trip near Tokyo. Doing day trips might be a little challenging given your party makeup.
15 days with packed itinerary seems tiring.
