The Yamashiro Tradition and the Tenka Goken — Kyoto's 'Refinement' and Five Sacred Blades

The Yamashiro Tradition — “The Sword of the Capital”

The Yamashiro tradition is the collective term for the schools of smiths that developed in Kyoto (Yamashiro province). Because it grew out of demand from the capital’s aristocracy, court, and temples, its style is defined by refinement rather than roughness. It is called “the aristocrat’s taste” or “the sword of the capital.”

Three Lineages of Yamashiro

In chronological order, the three principal schools:

• Sanjō school — Late Heian. Founded by Sanjō Munechika
• Awataguchi school — Early to mid-Kamakura. The “Awataguchi Six” and the tantō master Yoshimitsu
• Rai school — Mid-Kamakura to Nanbokuchō. Founded by Kuniyuki, through Kunitoshi, Rai Kunimitsu, and Rai Kunitsugu

Add to this smaller schools of Kyoto — Ayanokōji, Gojō, Nobukuni — for a fuller picture.

The Sanjō School — Origin of the Heian Tachi

The Sanjō school is the ancestor of the Yamashiro tradition. The name comes from residence at Sanjō in the capital. Its founder, Sanjō Munechika, was a late-Heian smith who, in legend, forged “Kogitsune-maru” at the command of Emperor Ichijō (the nō play “Kokaji”).

Munechika’s most famous surviving work is one of the Tenka Goken — Mikazuki Munechika. Following Munechika are Yoshiie, Arinari, and Kunimasa, whose “Tsurumaru Kuninaga” is an imperial treasure.

The Awataguchi School — “Awataguchi Six” and Nashiji-Hada

The Awataguchi school was a community of smiths at Awataguchi in the eastern hills of Kyoto (near present-day Chion-in). Established in the early Kamakura, it reached its golden age in the early to mid-Kamakura.

The Awataguchi Six

Kuniie is the founder, and his six sons became the “Awataguchi Six”:

• Kunitomo — Eldest
• Hisakuni — Goban-kaji
• Kuniyasu — Goban-kaji
• Kunikiyo — Tantō master
• Arikuni
• Kuniyoshi — Tantō master; father of Yoshimitsu

Nashiji-hada

The Awataguchi jigane is distinguished by nashiji-hada — an exceedingly fine granular figure. Polished up, it looks like the “nashiji” (pear-skin) ground of lacquer maki-e. The hamon is suguha-based, with tasteful small midare. The very definition of Yamashiro’s “refinement.”

Awataguchi Yoshimitsu (Tōshirō) — Tenka Sansaku Master of the Tantō

Within the Awataguchi school, Yoshimitsu (Tōshirō) stands apart. He worked only in tantō, and those tantō rank among the “Tenka Sansaku” with Masamune and Gō no Yoshihiro.

Yoshimitsu’s tantō have a thick kasane and are hardened in a tasteful suguha. Short but dignified, they were prized among daimyō in the Sengoku and Edo periods. Yoshimitsu tantō handed down in the Tokugawa, Maeda, and Date houses remain today as National Treasures and Important Cultural Properties:

• Atsu Tōshirō — National Treasure, Tokyo National Museum. Archetypal yoroi-dōshi
• Gotō Tōshirō — National Treasure, Tokugawa Art Museum
• Hirano Tōshirō — National Treasure, Kyoto National Museum
• Ichigo Hitofuri — Imperial treasure. Yoshimitsu’s only tachi

The Rai School — Kuniyuki, Kunitoshi, Kunimitsu, Kunitsugu

The Rai school is, with Awataguchi, the other major lineage of Yamashiro. Its founder is Kuniyuki (mid-Kamakura). A separate lineage from Awataguchi, it established a more warrior-oriented style.

• Kuniyuki — Itame-hada with utsuri; suguha to small midare. Stronger than Awataguchi
• Kunitoshi — Kuniyuki’s son. The central figure who developed the Rai school. “Nakigitsune” (National Treasure, Tokyo National Museum) is his best-known work
• Rai Kunimitsu — Late Kamakura to Nanbokuchō. Masterworks in tantō and wakizashi
• Rai Kunitsugu — Kunimitsu’s disciple. Absorbed Sōshū influence and is called “the Sōshū within Rai.” One of the Masamune Jittetsu

“Niji Kunitoshi” (mei cut as the two characters “Kunitoshi”) and “Rai Kunitoshi” (mei cut as three characters, “Rai Kunitoshi”) were once thought to be different people, but the two-are-one theory is now dominant.

Summary of the Four Elements of Yamashiro

• Jigane — Extremely fine nashiji-hada / ko-itame-hada. Bright, refined steel color
• Hamon — Suguha-based, with small midare and gunome mixed in
• Form — Slender, high koshi-zori, elegant
• Mei — Fine tagane work, dignified calligraphy

The Tenka Goken — Five Sacred Blades

The Tenka Goken — “Five Swords Under Heaven” — are the five most celebrated Japanese swords. All are from the Heian or Kamakura periods:

Name	Smith	Period	Present home	Designation
Mikazuki Munechika	Sanjō Munechika (Yamashiro)	Mid-Heian	Tokyo National Museum	National Treasure
Onimaru Kunitsuna	Awataguchi Kunitsuna (Yamashiro)	Early Kamakura	Imperial Household	Gyobutsu
Dōjigiri Yasutsuna	Ōhara Yasutsuna (Hōki)	Mid-Heian	Tokyo National Museum	National Treasure
Ōdenta Mitsuyo	Miike Tenta Mitsuyo (Chikugo)	Late Heian	Maeda Ikutokukai	National Treasure
Juzumaru Tsunetsugu	Aoe Tsunetsugu (Bitchū)	Early Kamakura	Honkō-ji	Important Cultural Property

Two of the five are Yamashiro-made — a marker of just how high the Yamashiro “refinement” stood.

The Five, One by One

Mikazuki Munechika

By Sanjō Munechika of Yamashiro, mid-Heian. Named for the crescent-moon-shaped “uchinoke” work that appears throughout the yakiba. Called “the most beautiful of the five swords.” Ashikaga shoguns → Hino house → Toyotomi Hideyoshi → Yodo-dono → Tokugawa shoguns → Tokyo National Museum.

Onimaru Kunitsuna

By Kunitsuna of Awataguchi in Yamashiro (youngest of the Awataguchi Six), early Kamakura. Named for the legend in which Hōjō Tokiyori received guidance from an old man (the spirit of the sword) in a dream, and, wiping off the rust himself, severed the leg of a demon on a nearby brazier. As an imperial treasure, public exhibition is extremely rare.

Dōjigiri Yasutsuna

By Ōhara Yasutsuna of Hōki, mid-Heian. Named for the legend that Minamoto no Yorimitsu used it to slay Shuten-dōji, the ogre of Mount Ōe. Hon’ami Kōtoku called it “the first of the Tenka Goken” — a leading position among the five. Tokyo National Museum.

Ōdenta Mitsuyo

By Miike Tenta Mitsuyo of Chikugo, late Heian. Handed down in the Maeda house, it was regarded as a spirit sword — “place Ōdenta by a sick person’s pillow and the illness will heal.” Ashikaga shoguns → Toyotomi Hideyoshi → Maeda Toshiie → Maeda Ikutokukai.

Juzumaru Tsunetsugu

By Aoe Tsunetsugu of Bitchū, early Kamakura. Named because Nichiren Shōnin wore it at Mount Minobu with prayer beads (juzu) wound around the hilt. Lost sight of for centuries, rediscovered in the Taishō period, and now held at Honkō-ji in Amagasaki, Hyōgo. Displayed publicly only once a year, on November 3.

Criteria for Selection

There is no definitive historical source for the choice of the five, but the presumed criteria are:

1. Craftsmanship — Each stands at the summit of production history
2. Illustrious provenance — Passing through shogunates, imperial houses, and famous warlords
3. Rich lore — Ogre-slaying, spirit-swords, religious associations
4. Age — All are Heian or Kamakura

Five blades that combine “craft + status + story + age” in the fullest measure.

“Five Sword Pilgrimage” — Modern Viewing

Seeing all five in person is a formidable undertaking:

• Dōjigiri Yasutsuna, Mikazuki Munechika — Tokyo National Museum (once every few years, with rotations)
• Ōdenta Mitsuyo — Maeda Ikutokukai (by inquiry, special exhibitions only)
• Onimaru Kunitsuna — Imperial treasure, essentially no public exhibition
• Juzumaru Tsunetsugu — Honkō-ji (once a year, on November 3)

For sword lovers, the “Five Sword Pilgrimage” is a much-longed-for journey. Few people manage all five in a lifetime.

Quasi-Tenka Goken

Blades that stand alongside the five:

• Ō-Kanehira — Ko-Bizen Kanehira, National Treasure, Tokyo National Museum
• Daihannya Nagamitsu — Osafune Nagamitsu, National Treasure, Tokyo National Museum
• Ichigo Hitofuri — Awataguchi Yoshimitsu, imperial treasure
• Sanchōmō (Yamatorige) Ichimonji — National Treasure, Okayama Prefectural Museum (purchased by Setouchi City in 2020 for 500 million yen)

From This Article to the Next

We have covered the five great producing regions of the kotō era and the Tenka Goken. The next article turns to the remaining tradition — Mino — and the Sengoku sword. Formed under Yamato and Sōshū influence, Mino gave us Kanemoto (Seki no Magoroku) with his sanbon-sugi, and Izumi-no-kami Kanesada. From the Ōei era to the sue-kotō period was an age of mass production. The distinctive contribution of Mino, sustaining the Sengoku daimyō as the “practical, combat sword.”
