Motoyuki Shibata isn't a typical Japanese.
He and his wife, Hitomi, don't own a car. They have a solar panel on the roof. They collect rainwater in an old whiskey barrel to water the plants, and they don't use dish soap.
Shibata's biggest luxury is a wooden Japanese soaking tub, which he built himself. He sits in the tub after he has thoroughly scrubbed himself. After the soak, the bathwater is recycled — and reused for washing clothes. The process is facilitated by a simple hookup.
Shibata guesses that about 5 percent of Japanese use a pump to send water from their bathtubs into washing machines.
After the clothes are washed, Shibata does what most Japanese do: He dries his wash on an outdoor clothesline. Most Japanese don't own clothes dryers. Their clothing hangs on television-antennae-like racks that twirl around on their railings.
"You get to see lots of clothes hanging. … Don't see that in America," Shibata says. "Space is very valuable here. If you can do without something, you do without it."
