Custom Japanese Signature Seal (Kao) – Bespoke Personalized Design

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.

With this service, your name and chosen words are transformed into auspicious kanji, creating a seal design that is uniquely yours.

Every Kao is fully custom-made, designed from scratch to reflect your identity and spirit. The result is not only a seal, but also an artwork that embodies tradition and personal meaning.
