I'm fliying from Narita to Chicago. Would you suggest I exchange yen to dollars at Narita or in the states? Thanks!

Everything is in the tittle, I know there are many places to buy second hand figurines but during my long stay in Japan I won a lot of them at the UFO catchers and I am looking to sell some of them. [...]

Isn't it like a specific day or week, maybe same day that companies/schools do/allow uniform change for summer wear? I'm guessing just before then is a good time to buy stuff in sales :)

I bought a new set of dresses to rearrange my wardrope, whats the place in tokyo to sell old dresses, 

Also,

welcome ideas of donating to charity, but need english communication :)

Is it worth the price? What's your experience?

I've heard you can eat momiji leaf tenpura in Osaka!?

I've seen in izakayas and restaurants, but not in supermarkets or konbinis. I'd like to buy for my friend as a present.

Also, do I need a special license to take it to the UK perhaps? Would love to buy one as a present for my dad who is interested in martial arts and that side of Japanese history.
