Alright. So I am on an STA in Japan (Shin-Yokohama) for 11 weeks now. During this time I will have a few weeks vacation as well. I'm pretty familiar with the Tokyo area right now, and I've seen most of the "big" wards (basically everything that is mentioned in Wikitravel), and I've had a great time so far...

Now, do you have any spontaneous tips on what I can do on my spare time (weekends and two weeks vacation)? My current plans are to go to Kyoto/Osaka for one week, and to stay in Yokohama/Tokyo during Obon week (since all "tourist" destinations will be very crowded in that time).

I am a big lover of japanese cuisine, and I enjoy both cultural destination as well as the more high-tech stuff.
