Subtitle: A collection of Japanese households with children
The exteriors of the houses seem to be built with extreme simplicity, but the interiors are often kept so neat and tidy that you'd wonder if a professional organizer or a minimalist icon had visited.
Given their circumstances, it doesn't look like they would hire a housekeeper at all.
Watching them, I get the feeling they naturally scrub their cars like crazy until they gleam.
Every single one of them has an exterior that is the epitome of simple and clear.
