Oh, OK a few notes:
YouTube didn't like Our Man using Rod Stewart, so Our Man had to replace the soundtrack with something free from them, and blow me if it isn't even better. Check it out here.
All the facts an' figures were from this Kyodo article here based on official (ie undercounted) stats from the Japanese Cabinet office.
The (Our Man preferred) soundtrack is Rod Stewart's Every Picture Tells a Story, which holds up quite well apart from the "slit-eyed lady" lines, but hey, his heart was in the right place, and it was 1972 forfucksakes.
Most of the moving pictures were shot two weekends ago during the Abiko summer matsuri festival - hence all the kimonos and chocolate bananas.
The rest is merely details.
