| Obverse description | Plain, uninscribed oval gold field exhibiting a characteristically hammered and smoothed surface texture, with faint horizontal striations across the face resulting from the hand-finishing process typical of Japanese feudal-era kin currency. The field is entirely devoid of legends, devices, or marks, presenting a broad, lustrous expanse of yellow gold. The irregular yet deliberately shaped oval flan displays the artisanal quality associated with provincial Japanese gold currency of the Sengoku period. |

| Additional information |
Hirumo kin are among the least-documented gold pieces of the Sengoku period, circulating in northeastern Honshu as local warlords increasingly minted their own currency outside any central authority. Mutsu Province in the 1570s was under the fractured control of competing clans — the Date, the Ashina, and others — none of whom had consolidated the region. Attribution of specific pieces to a single issuing authority remains contested among Japanese numismatists.
The name "hirumo" likely derives from a place associated with gold-washing or small-scale alluvial mining in the region.
