Yeah, I failed to mention I was already going to Akahibara. We already spent part of a day there and we'll hopefully come back again for more things. Thanks for the ideas.
We're also visiting Kyoto, Kamakura, Yokosuka, and Fujikawaguchiko (Mt. Fuji).
"Ah, a party! We haven't had one of those. It could be fun! So... what is a party?"
"You drink punch and eat CAKE! ...I think."
