| 正面描述 | Central square perforation surrounded by four raised kanji characters arranged in cruciform fashion within a broad, flat field: 寛 (Kan) to the left, 永 (ei) below, 通 (tsū) to the right, and 寶 (hō) above, reading clockwise from the top in the traditional East Asian numismatic convention. The boldly cast characters are rendered in a regular script style with strong, well-defined strokes that stand in high relief against the textured ground. A plain inner rim frames the square hole, and a raised outer rim borders the coin's circumference. The overall design follows the established format of the Kan'eitsūhō series, struck here as a presentation or commemorative piece in gold. |

The Kan'ei Tsūhō series, produced overwhelmingly in copper, occasionally appeared in gold and silver as presentation or ceremonial pieces rather than circulating currency. The 1657 date places this squarely in the year of the Meireki Fire — the single most destructive fire in Edo's history, which destroyed roughly two-thirds of the city and killed an estimated 100,000 people. Emergency expenditure and reconstruction demands severely disrupted the Shogunate's finances that year.
The KM#- reference reflects how poorly these gold presentation-format mon pieces are catalogued in Western references. Confirm attribution against Japanese specialist literature before pricing.
