What sparked the whole Japanese

What sparked the whole Japanese thing between Robyn and I was wondering what the heck Greenery Day is. Today is Greenery Day in Japan, a public holiday. Apparently it is normally the 29th, but was held over to today as the 29th was, of course, a Sunday. Well, now I know. Or for a more sideways view, refer to Tokyo Classified, which is definitely a cool site.
