I’d like to introduce this youtube Hakodate promo video. I was told that it was made by the City Hall.
As far as a I can see, the theme is “visit Hakodate before it’s destroyed by monster robots”.
Nice video, but I’m quite happy that “Long Now” is a better theme than this…

I found a link to Long Now ideas on a Japanese site: kanshin.com.
It seems that they also say that there is little text on “Long Now” in Japanese, but they do point to the Long Now Japan blog. Maybe it has some useful info for WMDFers.
