I hope to be there for 2009. I was in Tokyo with my friend 2007 July. 5 days "actually nights" we were in Roppongi Hills. I loved how clean it was, respectful people, the best Mc Donalds you can ever have, so hot and fresh, classic but LIKE NEW taxis I GUESS ALL WITH GPS, Auto doors, NOT A SINGLE hole on roads, There were DRIFT LINES/MARK on the way from Narita airport to Tokyo City and marks explained how well they can drift... If you smoke its cheap to buy a pack at about 300 yens or 3 AUD. My friend did smoke and he never had to buy it... I dont know I THINK BECAUSE IT WAS CHEAP ppl leave their cigarette packs in the club, smoking only a few of it and leaving it with more than half... Sushi??? So fresh, food was the best as well, trains =)) The subway line in Japanese is a joke but simple to understand, dont worry station staff is there to help all you need to do tell the name of the place you are off to and he ll let you know how much is the ticket and which numbered station you ll get off. Waiting for train??? =) All we did about 2 mins standing... In Roppongi at night Nigerians will try to get you into strip clubs, massage saloons while WE BAGGED for a decent club and cant really say it was good in Roppongi. In shinjuku or shibuya there are a lot of better choices. PPL say JAPAN is expensive and I wonder "SUCH AS???" I can not recall anything was overpriced or considered RIP OFF.... Prices AS MUCH AS WE COULD OBSERVE IN 5 DAYS was really reasonable...
One thing to avoid is Tokyo Disneyland... We wasted a day in there all those Japanese kids stearing at us specially my 2 meter tall friend =)) We gave some of the ride tickets to others as a goodwill and went back to nightlife scene...
As I mentioned earlier I hope to go back probably next year for Autosalon. I want to spend at least 2 weeks there. There are lots of things to see. Digital camera specially nice DSLR is a must to appreciate the beauty of the country...
