This name ranks 153rd among Japanese family names and is distributed nationwide, though it carries strong spiritual and religious connotations throughout its usage.

This spiritual layer adds depth to the name's meaning, reflecting the integration of religious identity into family nomenclature during Japan's formative periods.
