After reading your post, I too want to go to Japan.
[quote name='Rodimus']I've been to Japan 4 times in the last 8 years and every time I try to do something new. It's cool you're going to Kyoto. I was there several years ago and loved it. People are so quick to recommend Akihabara (which worth a trip) but I prefer the more traditional Japan. Go out and eat the local food as much as you can. It's a bit intimidating but try as many different cuisines as you can. For some examples: ramen, sabu sabu, monjayaki, yakiniku, sushi, etc. If you're tired of Japanese food go find a Moss Burger, Mr. Donuts. Heck, even going to McDonalds in Japan is an experience just to see how happy the staff is.
I highly recommend going to a Hot Spring or Bath House. I can't stress this enough. Go to one. Of course I recommend the hot springs over a bath house but either will be a great way to immerse yourself into the culture. There's tons of bath houses in Tokyo. It's something many international people don't experience, and that's a shame. I guess getting nekkid is too much. My fondest experience was going to a hot spring near Mt. Fuji. It was a gorgeous day and a picturesque view of Mt. Fuji in front of me while I soak in the spring. Heaven
As for Tokyo, I'll recommend:
Asakusa - Most famous shrine in Tokyo, a bit touristy but worth the trip.
Shinjuku's Electric City - Entertainment district often featured in video games
Sunshine 60 in Ikebukuro - a huge shopping mall
Akihabara - Obvious choice, Super Potato is here. A kick-ass video game store but way over priced. I actually prefer going to a Book Off whenever I find one. The're all over Japan. I've found some great video game deals here.
Tokyo Metropolitan Government Building - A very tall building in Shinjuku. The top has a great 360 view of Tokyo. Better than Tokyo Tower.
Studio Ghibli Museum - Not really a must but it's a cool place to visit.
Kamakura - Lots of traditional buildings and shrines. Great place to see some real Japanese culture. If you're lucky there may be a festival going on.
Yokohama - Port part of Tokyo. Ships, amusement parks, huge ferris wheel.
Tsukiji Fish Market - This place is an experience just to walk around and see all the different fish/seafood for sale. Just don't go in the morning, it's busy. Also a great place for restaurants if you want the fresh catch of the day.[/QUOTE]
