Get both the Metropolitan Subway Map and a Japanese Railway Map. Some stations are not listed on one, but may be available on the other.
The Government Metropolitan Building Observation Deck has free entry, and is a spectacular 360degree view. The Tokyo Sky Tree is Y3000 and Tokyo Tower ranges from Y900 to Y1600, depending which observation deck you want to enter.
Sky scrapers are the safest place to be during an earthquake; they are designed and re-enforced to withstand the shock. If you are on the street during an earthquake, run into a high-rise building.
You cannot get to Asakusa on your JR Pass (this is where Senso-Ji Shrine is located).
Tours of The Imperial Palace need to be booked in advance
Akihabara is best for electrics.
Shinjuku is the best district for bars and nightlife
The bar Jumangi 55 in Roppongi has Y1000 all you can drink for ladies; Y1000 “as many drinks you can drink in two hours” for men. (this deal may change in the future, look it up before you go!)
The Golden Gai in Shinjuku is recommended, but keep in mind that some of the bars in the complex do not cater for westerners
Robot Show in Shinjuku: Y7000 for the show, meals and drinks are NOT included in the ticket price
Ueobei in Shinjuku is a cheap and cheerful place of lunch! (see this blog for further details http://thetruthfultravellers.com/2015/03/06/robots-crusty-wakeup-calls-richard-senso-ji-and-german-uno/ )
The Cat Cafe Calico in Shinjuku is crap. Don’t waste your time, your feet, or your Y1000
