Mitsudomoe Katana Specifications

Triple Tomoe Tsuba — Openwork Symbol

The tsuba is matte black iron-alloy with the mitsudomoe (三つ巴) cut clean through the metal — three comma-shaped voids creating negative space that reveals the habaki beneath. The openwork makes the symbol structural rather than decorative: light passes through, the blade collar glows behind it, and the guard's silhouette changes depending on rotation angle. No other tsuba in our catalog uses a mon as its primary structural element.

Engraved Habaki — Gold Medallion

The habaki surface carries intricate floral scroll engravings covering every visible face — dense, fine linework that rewards close inspection. At its center sits a gold mitsudomoe medallion in a circular frame, matching the gold emblems on the saya. The Mitsudomoe Katana places more decorative detail on its habaki than most blades place on their entire koshirae. The contrast between the silver-engraved body and gold medallion creates a jeweler's level of finishing on a component most buyers never examine closely.

Gold Crest Saya — Four Emblems

Glossy black lacquer — deep, reflective, automotive-grade finish. Four gold brass mitsudomoe emblems sit at regular intervals along the scabbard's length, each one identical in size and precisely positioned. The kojiri (end cap) is carved wood with a mitsudomoe cutout — the sixth iteration of the symbol across the entire sword (tsuba, habaki, four saya emblems, kojiri). The Mitsudomoe Katana treats its mon the way a clan would: repeated on every surface that identifies the blade's allegiance.

Mitsudomoe — Earth, Heaven, Humanity

The mitsudomoe (三つ巴) is a Shinto and Buddhist symbol representing three forces in eternal rotation — earth, heaven, and humanity cycling without beginning or end. Samurai clans adopted it as a mon (family crest), Shinto shrines display it at entrance gates, and martial arts schools use it to express the cyclical nature of combat training. The three tomoe (comma shapes) suggest perpetual motion: water flowing, wind circling, energy transforming. On this blade, the symbol appears at seven different scales and materials — openwork iron, engraved gold, cast brass, carved wood — each iteration a different interpretation of the same motif.

Handle — Blue Menuki Accent

Black cotton ito over synthetic rayskin with blue menuki breaking through the dark wrapping. The blue is the only color aside from gold on the entire Mitsudomoe Katana — a water reference tying back to the tomoe's association with flowing energy and Shinto purification. The restrained palette (black, gold, one accent blue) ensures the repeated mon reads as intentional heraldry rather than visual clutter.

Display

Ships with a natural wood stand. The glossy black saya with gold crests creates a striking shelf presence — the reflective surface doubles the gold emblems in its own lacquer. Position under a single directional light to maximize the glossy depth. Browse our buying guide for display pairing options — the Mitsudomoe Katana's black-and-gold heraldic palette sits naturally alongside the Full Black and the Obsidian.

Frequently Asked Questions

What does mitsudomoe mean?

Three tomoe (comma shapes) in eternal rotation — a Shinto/Buddhist symbol representing the cycle of earth, heaven, and humanity. Also widely used as a samurai clan mon and martial arts emblem.

How many times does the symbol appear?

Seven: tsuba openwork, habaki medallion, four saya brass emblems, and the carved wooden kojiri. Each uses different materials and techniques.

Is the tsuba solid or openwork?

Openwork. The three tomoe shapes are cut through the iron-alloy, creating negative space. Light passes through the guard to the habaki beneath.

What are the blue accents on the handle?

Blue menuki — small ornamental fittings beneath the ito wrapping. The only non-black, non-gold color element on the entire sword.

Is this a clan-specific design?

The mitsudomoe was used by multiple clans and institutions — not exclusive to one lineage. It remains one of Japan's most recognized heraldic symbols across Shinto, Buddhism, and samurai tradition.
