Antique Japanese Sword Tachi attributed to Den Yamashiro Ryokai with NTHK Yushu Saku Certificate

【Description】

Summary

 This blade is attributed to Den Yamashiro Ryokai (伝 山城了戒), who was active during  the late Kamakura period in Yamashiro province (today’s Kyoto). It is said that he was a son of Rai Kuniyuki (来国行) and a younger brother of Rai Kunitoshi (来国俊). Both of them are renowned swordsmiths throughout Samurai history. 

 Ryokai founded his own school, and the apprentices were allowed to use Ryokai in their maker’s names. Ryokai’s son was Ryokai Hisanobu, who took over the school. And his apprentice Ryokai Yoshisada also run the school after Hisanobu. However, Ryokai Yoshisada had to evacuate.  Yamashiro province during the late 14th century because the battle between the south emperor court and the north emperor court became severe. And as a result, Kyoto city was burnt (the late 1300’s). We called it the Nanbokucho war when the Japanese imperial court was separated into two. 

 Ryokai Yoshisada managed to escape and arrive in Kyushu island at Tsukushi province (today’s Fukuoka prefecture), looking for better opportunities. And, Yoshisada founded Tsukushi Ryokai school there. Among Japanese sword experts, Ryokai school in Tsukushi province is called Tsukushi Ryokai to distinguish it from the Ryokai school in Yamashiro province. 

 

Yamashiro Den

 Yamashiro province was famous for its sword-making style called YAMASHIRO-DEN. YAMASHIRO-DEN’s origin dates back to the Heian period (794 A.D) when the capital city was moved from Nara to Kyoto. The swordsmiths in Yamashiro province initially prospered by forging swords for court nobles and imperial families. Later on, they also forged swords for feudal lords after Samurai military government took control of Japan. There are so many renowned swordsmiths from this region.

 It is said that the founder of YAMASHIRO-DEN was Sanjo Munechika. And there were four prestigious main branches in this region. They are Sanjo, Rai, Nobukuni, and Awataguchi. 

Tachi and Tachi Koshirae

Based on  its characteristics, the board of education in Niigata judged it as a Tachi. Tachi was mainly used by an armored Samurai with one hand on horseback from the Heian period (794-1185 A.D.) until the early Muromachi period. TACHI was suspended loosely on the left waist with its edge facing the ground so that you could draw it faster to cut down soldiers on the ground. Because of its gorgeous looking, having a Tachi-style sword mounting became a social status among Samurai.

 

Yushu Saku Appraisal

This blade has successfully passed the Yūshū-tō (Excellent Sword) examination conducted by the NPO Tōken Hozonkai, a respected Japanese sword preservation organization.

The Yūshū-tō certification is not easily obtained. During the appraisal process, swords are subjected to strict and detailed evaluation by qualified judges with deep knowledge of traditional Japanese sword craftsmanship. Factors such as forging quality, hamon activity, balance, preservation state, and historical importance are thoroughly examined.

Only swords that meet these demanding standards are awarded this distinction. As a result, the Yūshū-tō paper is regarded as strong evidence of both authenticity and superior artistic and historical merit.

 

*Please keep in mind that there is a couple of Kitae Kizu on this blade. If you like to see the detailed condition, please feel free to contact us.

 

【Blade】
Cutting Edge Length (Nagasa): 71.6 cm (28.2 inches)
Curvature (Sori): 2.7 cm (1.06 inches) 


 

Hamon
The crystalline structure which forms along the cutting edge of a blade as a result of the hardening process.
Jimon (Jihada):
Visible steel surface pattern created by folding and hammering during forging process.



Kissaki: Kissaki is the tip of the Japanese sword.

Nakago: Nakago is the tang of the Japanese sword.

 Japanese swordsmiths left the black rust on the tang because it prevents red rust while the tang is in its handle. And the discoloration of the tang was created over time, and it is a great indicator for a Japanese sword specialist to estimate when the sword was forged.

 

Koshirae: Koshirae is the mounting of the Japanese sword. There are several parts that consist of Koshirae such as Saya (Scabbard), Tsuka (Handle), Tsuba (Handguard).

 This blade is stored in Tachi(太刀) Koshirae. Tachi was mainly used by an armored Samurai with one hand on horseback from the Heian period (794-1185 A.D.) until the early Muromachi period. TACHI was suspended loosely on the left waist with its edge facing the ground so that you could draw it faster to cut down soldiers on the ground. Because of its gorgeous looking, having a Tachi-style sword mounting became a social status among Samurai.

 

Fuchi-Kashira: A pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.

 The theme of this Fuchi-Kashira is Karakusa (Arabesque, 唐草). It is a pattern in which stems and leaves of vines are twined and make curves. Since ivy has a strong vitality and grows up without interruption, people regarded this design as a symbol of prosperity and longevity. Vine is called Tsuru (蔓) in Japanese, and it has another pronunciation; “Man.” There is a word 万 (it is also read Man), which means ten thousand. In the Karakusa pattern, leaves and vines are connected like Obi (帯, belt). The word “帯” can also be read “Tai.” Due to its pronunciation, the term “代 (Tai)” is associated. From this word-association game, an idiom 万代 is associated, and it means a thousand generations. In other words, we could imagine that people used this design wishing prosperity and longevity for their clans for a long time.


Tsuka and Menuki: Tsuka is the handle of the Japanese sword and Menuki is its decoration.

 The motif of this Menuki is Dragon (Ryu, 龍). Initially, the dragon is an imaginary creature found in ancient Chinese traditions or myths. Furthermore, it is regarded as a symbolic beast of auspicious signs. Its body is likened to nine animals: antlers are deer, the head is a camel, eyes are demons, the neck is a snake, belly is Mizuchi (蛟, mythical animal in Japan which looks like a snake and have a horn and four legs), scales are fish, claws are falcons, palms are tigers, and ears are cows. It was thought that the dragon would reign at the top of all animals because of its odd-looking appearance.

 In ancient China, the dragon pattern was used for emperors’ clothing so that people strictly defined its shape or even the number of nails. On the other hand, the dragon pattern does not have detailed rules to represent classes in Japan. However, still, it maintains its meaning as the all-purpose auspicious pattern.

 Also, in Japan, there is a belief that worships dragon as a water god and is called Ryujin Shinkou (竜神信仰). Since rice cultivation flourished in this country, water is always an essential resource. Therefore, the dragon motif has been familiar to Japanese people since a long time ago. 

    

 

Tsuba and Habaki: Tsuba is the handguard for the Japanese Sword and Habaki is the equipment to make the blade not touch its scabbard inside. It prevents the blade from getting rusty and chipped. 

 This Tsuba is made in a yotsu-mokkō-gata (四つ木瓜形) form, a classic outline derived from the rounded, lobed shape of a sliced gourd.

 At the four corners you can see inome (猪目, boar’s eye) cutouts, also described as inome-sukashi. Because of their curved point-and-lobe profile, they often look like small heart shapes at a glance, and they are not just decorative. Inome are widely used as an apotropaic motif, believed to help ward off evil and misfortune while also adding lightness and rhythm to the design.

  Also, the design of Karakusa is depicted on the surface.

Saya Saya is the scabbard for the Japanese sword.  

The Taiko Kanagu (太鼓金具) on this Saya is decorated with the Mitsuuroko family crest. The name Mitsuuroko comes from the way three connected triangles resembles the scales (uroko) of a snake, and ‘mitsu’ means three, so it came to be called Mitsuuroko (three scales). The motif has been used in Japan since ancient times and can even be seen in wall paintings from the Kofun period (古墳時代). It is well known for its protective, talismanic power against evil, and one of the most famous Samurai families to use this crest was the Hojo clan (北条氏).

 In addition, this Saya is finished woth Nashiji laquer (梨地塗り), a technique that creates a subtle, pear-skin texture with a softly shimmering surface, and decorated with Gosan no Kiri family crest (五三桐). Gosan-no-Kiri Monyou (五三の桐文様) is a popular design that the paulownia motif is used. This pattern was once used by the imperial family and people in authority at that time. Today, it is permitted to use by ordinary households and is appreciated as their family crests. According to a tradition, Houou (鳳凰, Fenghuang, a kind of sacred beast) rests its wings at the paulownia tree; therefore, it has come to be regarded as a holy plant. 

 

 

Authentication Paper: NTHK Yushu Saku Certificate for the blade (No.13007)

 NTHK, also known as NPO Nihon Touken Hozon Kai, is the oldest organization for sword authentication of Japanese swords in modern times. It was established in 1910 during the post-Samurai era. They authenticated the blade on December 21st in the 7th year of Reiwa (2025). They appraised it as Yushu-Saku To (優秀作刀): an outstanding sword considered especially worthy of preservation for Japanese society. The purchaser will receive this original certificate as well. We can also translate what is written into English and make a PDF file for your record if you request.
