01 / Aoyagi Post Town
A channel hollowed under the stone wallserved from morning washing to livestock water.
The village says Aoyagi sits on a narrow slope, with houses built atop stone walls and a waterway running beneath them. Water from a channel hollowed out under the wall was used for washing and for watering livestock, and the houses opposite used it too. A record from about 1824 gives its length as 3 cho and its width as 3 shaku.
