A friend over at Tokyopia.com pointed out this soon to be released movie called Lost In Translation about a couple of foreigners in Tokyo.
Advance word is that it's very good and I guess we are all hopeful since many of us at Tokyopia.com have gone through the isolation issue of being a foreigner here and plus I'm sure there are many interesting things in the movie. Maybe you can get a taste of what Tokyo is like. Bill Murray is awesome so I have high hopes.
