| Obverse description | Central square hole framed by four raised Chinese characters arranged in a cruciform pattern reading clockwise from top: 寛 (Kan), 通 (Tsū), 永 (Ei), 寶 (Hō), together forming the legend 'Kan'eitsūhō' (Kan'ei Currency). The characters are rendered in a notably wide, bold style characteristic of this Bosen variety. A plain raised rim encircles the design field, and the overall surface displays the typical patina of a cast copper-alloy coin. |

| Reverse description | Eleven wave-pattern segments radiate outward from the central square hole, rendered in low relief and divided by incuse lines to simulate stylized ocean waves filling the entire field. The hiragana character ト (To) appears above the square hole, serving as the mint or furnace mark identifying the issuing facility. A plain raised rim borders the design, and the bold, wide casting style corresponds to the Bosen pattern designation. |
