low entrance door in Edo-period bathhouses
historical term
Historical term for a small, low door at the entrance of a public bathhouse (sento) during the Edo period, designed to minimize heat loss and keep the bathwater warm.
In Edo-period public bathhouses, there was a low entrance called a 'zakuroguchi'.
The zakuroguchi was made small to prevent steam from escaping.
