Can’t believe I missed this: October 18th is “Statistics Day” in Japan.
There are posters. (Disclaimer: I can’t read the kanji, so hopefully this is a Statistics Day poster and not, say, a High-Altitude Ballooning Day poster.)
And here is an exhaustive set of Japanese statistics, all wrapped up in a spiffy Flash interface. Sample mindboggling statistic (although I’m sure this sort of thing is not confined to Japan):
At 2:21am on Tuesday in Japan, 152,878 people are commuting for work.
At 2:04pm on Tuesday in Japan, 30,565 people are making sweets as a hobby.
