I'm planning on a trip to Tokio anything I really need to know?

Don't. Buy. Anything. From. Akihabara. Just about everything is overpriced. Go to Nakano Broadway or Ikebukuro for your otaku needs. Also be warned, adult stuff is around just about every corner. Expect to see ecchi just about as much as you see McDonalds in America (if not more so).

Your right but...I bought this Guts figure there. It was my first time in Japan and I wanted a memorable souvenir. Let's just say it hurt my wallet alot. :( But I have no regrets.:)

Hey hey. Ecchi is the bomb!:)

I've never been to tokyo myself but I am planning a trip in June, from people I've talked with Shibuya is the best all around place for the night life (bars, pubs, clubs, and outside drinking) If your looking for a bigger variety of bars with an international crowd Shinjuku's Golden Gai is your spot. From what I've been told I would avoid Kabukicho if you dont speak fluent japanese. A few people have told me about being over charged for drinks/riped off, and one person even said the got roofied and woke up to a bunch of crazy charges on there credit card. If its true or not im not sure. But from what I've heard Kabukicho is fine to walk around just dont drink there. Let us know how your trip is im anxiously waiting for mine

K House in Asakusa is a great hostel to stay at while in Tokyo. Clean, inexpensive, and great for your first trip. Oh an the maps of Tokyo are make things seem much further apart than they actually are.
