First off thank you all for the replies.

JDiver; Thanks I will check that out

Joejones; Disney isn't the only thing I want to check out :-) I will look into the parks and aquariums that you have mentioned and thanks.

robyng; I just noticed that fugu is out of season :-( and Unagi is my favorite and can not wait to try sushi in Japan. I'm not totally ruling out temples, I just don't want to spend a lot of time to get to any, I'll hit the local ones. I do like people watching and will be checking out the anime, electronics and other areas. Thank you.

abraxis; I think I'll be there to late for any festivals :-( (see below) Thanks

hailstorm; Great band btw :-) I've been to both Disney's in the US and looks like Tokyo Disney is pretty much the same, so I figure I can do that in one day. I just don't know about Disney Sea, as to how big and how much there is actually to do there. I probablly will want to see and do at least 90% of the things there. So should that be 2 or 3 days(3 or 4 day pass)?

More about me; like I said before, I'm adventurous and will try anything at least once and love to try new things when I can. I like to walk around and see/ explore things. I will check out Shibuya, but I doubt I'll be doing any shopping. I'm more comfortable in a thrift store or flea market than a high end store at a mall or something like that. Like, I'd rather shop at Walmart than Nordstroms.
Some of the things that I like to do(but not limited to) I know a few of these things don't fit well in Japan but here they are anyway, paintball, arcades, amusement parks, fairs, carnivals, travel, anime, target shooting, blading, exploring new things, bungee jumping and a lot more.
When I'm on vacation, I'm on the go, more than not. up and out early and back late. I feel that I'm paying so much for a vacation, I need to take full advantage and do what I can.
I've done a lot of reseach and have a list of things that I want to do and see, I am just looking for your opinions and info to fill in a couple more days. I'll be in Tokyo for 12 days and so far I have Edo(1d), Disney(3-4d) Fugi Q(or other more recomended) (1d), an aquarium(1d) so that leaves roughly 5 days to explore Tokyo and add anything that is a must do while I'm there.
So what do you think? Any recomendations? FYI, I'll be there from Aug 30 and leaving Sep 12th. Thanks again :-)
One more thing, I asked before. I saw something on a map of Tokyo about Pachinko Tower, but can't find any info on it. Anyone know what that is? Just curious.
