Japanese Signature Seal (Kao) – “Shinhai”真拝

Kao – Japan’s Traditional Signature Culture

Kao (Kaō) is a unique form of signature once used by samurai, monks, and cultural figures to express their pride and identity.
Famous warlords such as Oda Nobunaga, Toyotomi Hideyoshi, and Tokugawa Ieyasu each had their own distinctive Kao, leaving behind marks that symbolised their presence in history.

The Kao “Shinhai” (真拝) carries a special meaning.
“真 (Shin)” represents sincerity and truth, while “拝 (Hai)” signifies the Japanese act of showing reverence by joining one’s hands together in prayer or respect.
It was also inspired by the name Hidi, often seen in Switzerland, which is expressed through the kanji “拝.”
This Kao embodies sincerity and respect through its form.
