Actually I'm planning my trip very carefully because I don't want to miss a thing. First of all I'll be in Aomori during the Neputa Matsuri, it's been told that is wonderful and I've already booked the hotel in Hirosaki. I've planned to stay in some onsen such as Aoni onsen, Tsuta Onsen, Goshogake, Nyuto etc, the problem is that the most interesting "secret" ones have the site only in japanese and I can't book a room from Italy without knowing the language.
I will do this trip with my boy-friend and we rent a car for 20-25 days, I think that is the best way to visit Tohoku Region without loose too much time.
Fortunately there's internet!! How could we have lived without it?
