A lot people is complaining about the missing cities, mistakes, low quality in the new iOS 6 Maps application. In fact, it’s a new app, it’s still a work in progress. I prefer to think about it as a Beta version, just to avoid my disappointment to grow.
If you are in Tokyo I recommend to follow this path.
Get out at Kudanshita station, exit 2 and walk all the road down to Jimboucho to find tons and tons of old books. Even if you don’t understand Japanese, it’s very interesting to see the atmosphere in there. Then you’ll find streets dedicated to sports, then streets of music and finally you will be in Akihabara, the geek kingdom.
