I got this book from Tourist Information Office in Roppongi Hills, last weekend. It comes in two types, booklet and map. I've used this kind handy guide book long time ago, but that time i got it from Tokyo Metropolitan Government Building in Shinjuku. So i think you can get it from any tourist information center around Tokyo including Airport. If you plan to traveling around Tokyo, i'll recommend this book because it is free, easy to read and very informative.
|Sorry it's bit crumpled up :P|
It doesn't matter you can't read Japanese, because if i'm not wrong, they have at least 9 different languages version. Subway and Water Buses Maps are included. There are explanation about sightseeing spot in 19 Areas with such information as : what to see, access, open hours, admission, address, phone number, website. Moreover, it lists up about Gardens, Zoos, Museums and Art Galleries, & Amusement Parks too. The interesting part is explanation about "how to use Japanese Style Facilities", because if you ever come to Japan... you will understand how difficult to use women toilet with complicated flush button in Japanese Character especially if you cannot read kanji/hiragana/katakana.
Anyway, discount coupons for Gardens, Zoos and Museums are available inside the book. But No discount Coupons for Amusement Park :)
