"Two rooms that were each about 12 square feet"

Big difference between 12 square feet (a 3' x 4' closet is 12 square feet) and 12 feet square, which would be 12' x 12' (144 square feet). I suspect the author meant 12' x 12'.

he's talking Tokyo Japan...
so it's a safe assumtion he is correct with his statement of 2 -12 square feet rooms.

I've been there and have seen such small 'homes'...
