I first ran into this book in 1990, when I made my first trip to Japan on business. Since then, I have had 3 editions, and, as I now live in Tokyo, my dog-earred copy travels in my briefcase or backpack everywhere I go.MOST of Tokyo has signs using Roman characters (romaji), but, there are still some train stations, or street signs that are in kanji characters only.Lost? You can use this map to "match" the characters, even if you cannot read the kanji! Every station, street, river, ward, neighborhood is printed both in romaji and kanji. There are train maps and subway maps, with banks, hotels, and other places well marked.I invest in each new edition right away, and I give this book as a gift to each of my friends who come visit me in Tokyo, as well as each new ex-patriot who arrives in my office!
