Thank you for reply!
Yes I want to do a lot of things.. maybe I must change something.. anyway is plan work in progress and I'm interested to know your opinion about the place to visit.
So Roppongi is not a safe place ... in the night ok I take the suggestion Akihabara in day 2 skip Roppongi.
Just two question .. in Akihabara at what time shops closed ? Is good to stay here for nightlife (I mean early from 8pm to 12pm)
I also change my plan and I add a new day in Tokyo at Shinjuku and i will visit the Tokyo Metropolitan Government Building and maybe Shibuya just for a little walk.
