There are a couple of attractions in Japan that have been around for a while but seldom think of. One of them is Tokyo tower. I'd say less than 50% of the people in Tokyo have ever been to Tokyo tower, and about half of those that have been there haven't been up to the observation deck (I'm one of them, ha haa) But its been a symbol of Tokyo for almost 50 years now. Because of the expansion of digital broadcasting(Japan is going 100% digital in 2011) they are going to build a new one which is supposed to be built sometime around 2008. The other thing that the Tokyo tower symbolizes is midnight. In general the lights that light up the tower go out at 12 midnight so its kinda a sign to tell everyone (well most people) its late enough to head home.
