This Shintō-period katana carries one of Kyoto's most storied signatures: Awataguchi Ōmi-no-kami, a title-name associated with the Mishina school, the lineage that dominated high-end sword production in the imperial capital through the Edo period. The blade measures 66.3 cm with a restrained 0.7 cm sori — a flatter curvature typical of mature Shintō production, where the emphasis shifted from battlefield sweep to refined geometry and cutting precision. Three mekugi-ana confirm a blade that has passed through multiple generations of use and mounting changes, each one evidence of a sword valued and worn rather than stored.

The defining feature of this blade — visible and commanding in the photographs — is the hamon: a full, rhythmic gunome running the entire length of the cutting edge. The peaks are round and even, the valleys clean, the overall pattern maintaining a disciplined regularity that is the unmistakable signature of the Mishina school's technical approach. This is not the quiet, restrained hamon of conservative Yamashiro work — it is a bold, confident tempering line with a wide nioi-guchi (boundary zone) and active nie contributing brightness and depth throughout. The boshi in the kissaki turns back with controlled activity, closing the hamon neatly at the point. The overall polish presents the blade in excellent condition, the ji (body steel) showing clean, well-settled surfaces consistent with quality Shintō forging.

The nakago retains a clear two-line inscription on the omote face, partially cut (suriage notation on the toroku-sho indicating the tang has been shortened at some point — as noted by the "以下切" suffix, meaning "the rest is cut away"). This is common for swords of significant age that were remounted and shortened to fit new tsuka proportions. Three mekugi-ana confirm multiple remountings across centuries of use. Despite the suriage, the surviving portion of the mei is clear and well-chiseled.

Koshirae Details

The koshirae assembled for this blade is coherent, refined, and thematically unified — the work of a collector or commissioner who understood that good mountings tell a single story across every component.

The tsuba is an oval tatemaru-gata iron plate of excellent quality, decorated on the omote face with a scene of waterfowl among reeds: wading and flying birds — likely herons or mandarin ducks — rendered in relief and silver inlay, with ashi (reeds) picked out in gold hirazōgan against the dark iron ground, and the suggestion of flowing water below. Two additional small birds appear in the upper field, one in silver. The reverse face is intentionally understated — the same dark iron, with only a few small gilt details near the base, allowing the omote composition to lead. The overall quality of the inlay work, with its clean gold reed leaves and precisely placed birds, places this tsuba well above common production.

The fuchi is darkened metal — likely shakudō — engraved with a monkey among pine trees (saru to matsu) in fine low relief: a monkey with gilded eye clings among dense pine branches and needle clusters, the scene wrapping the full circumference of the collar. A fine gold ichimonji border runs along both edges of the fuchi, framing the composition with precision. The kashira (Image 6) is the finest single piece in the ensemble: an oval shakudō cap carrying a high-relief hawk or eagle — wings spread, talons gripping, rendered with individually worked feather scales in a warm copper-gold tone against the dark ground, the eye inlaid in a contrasting metal. Waves or clouds fill the lower register. The predatory bird and chrysanthemum pairing is a classic combination in Edo-period tosogu (sword fittings), carrying associations of martial prowess and imperial dignity.

The tsuka is wrapped in grey-green moegi (olive) silk braid in the hishimaki diamond pattern over dark samegawa (ray skin). The menuki are dark metal figurative pieces — seated figures or warriors — consistent with the sober, refined character of the overall mounting. The saya is finished in glossy kuro urushi (black lacquer), carrying a black braided silk sageo. The entire ensemble projects the restrained authority appropriate to a Kyoto-school sword of this quality.

Swordsmith Background

The signature Awataguchi Ōmi-no-kami combined with the counter-signature Shigeyoshi Hyōe-no-jō places this blade within the Mishina school of Kyoto — one of the most important smithing lineages of the Shintō period. The Mishina smiths worked under the prestigious Awataguchi place-name, invoking the ancient Yamashiro tradition of the imperial capital, and several generations held the court title Ōmi-no-kami (Governor of Ōmi Province), a mark of distinction awarded to swordsmiths of recognized excellence.

The Mishina school is particularly associated with a distinctive regular gunome hamon — the even, rounded peaks visible throughout this blade — and with a high level of finish and consistency that reflected the school's position supplying swords to Kyoto's wealthy merchant and samurai clientele during the Edo period's long peace. Their work was never merely functional: Mishina blades were display pieces as much as weapons, combining reliable cutting geometry with an aesthetic clarity that reads immediately even in photographs.

The suriage (shortened tang) with three mekugi-ana is telling: this blade passed through enough generations of active use and remounting to require new proportioning. That is not a flaw — it is biography written in steel.

School History: Mishina and the Awataguchi Tradition

The name Awataguchi carries enormous weight in nihonto history. In the Kamakura period, the original Awataguchi smiths of Kyoto — Kuniyuki, Hisakuni, Kunimitsu — produced some of the most refined blades ever made in Japan, prized above almost all others for their elegant, quiet beauty. The Shintō-period Mishina school consciously invoked this ancient lineage, working in the same district of Kyoto and styling their signatures to connect their work to that golden age.

The Mishina lineage active through the Edo period maintained production of high-quality blades for Kyoto's civilian and samurai market — a clientele that demanded aesthetic refinement as much as functional excellence. Their characteristic regular gunome hamon became a recognizable house style, consistent enough across generations to serve almost as a trademark. Combined with their Yamashiro-influenced ko-itame jihada and well-controlled kissaki geometry, Mishina blades represent Shintō production at its most polished.

A blade signed Awataguchi Ōmi-no-kami, with a period koshirae of this quality, is exactly what the Mishina school was producing for Kyoto's most discerning buyers: a sword that functions as both weapon and object of beauty, carrying a name that resonates across eight centuries of Japanese sword history.
