Antique Japanese Sword Daisho attributed to Naminohira/Echizen Seki with NBTHK Tokubetsu Hozon CertificateHozon Certificate



 This Katana is attributed to Naminohira (波平) during the early Muromachi period (Approx. 600-650 years ago), according to its NBTHK’s appraisal. Naminohira(波平) was one of the most influential schools in Satsuma domain (Today’s Kagoshima prefecture), founded by a swordsmith named Masakuni (正國) during the late-Heian period(Late 12th century). The swordsmiths in this school were known for having their name with one of these letters, 行(Yuki) or 安(Yasu). From the late-Heian period until the end of Samurai times(Late 19th century), the Naminohira family had kept the mastership for a thousand years.

 The Naminohira swords were cherished among Samurais in the marine army, mainly because the name Naminohira(波平) means “Tides are quiet.” in Japanese. The origin of the name Naminohira dates back to the school’s foundation. It is said that the founder Masakuni was originally from Yamato domain (Today’s Nara prefecture). The legend says he was able to calm the waves by dedicating his sword to the sea when his school in Yamato sailed to settle in Satsuma domain. Since then, he began to use the title “Naminohira Yukiyasu (波平行安)” – “Tides are quiet, easy to go.”


 This Wakizashi was attributed to Echizen Seki (越前関), who was a group of swordsmiths who moved from Mino province (Today’s Gifu prefecture) to Echizen province (Today’s Fukui prefecture) during the Keicho era (1596-1615: Late Azuchi Momoyama-Early Edo period).Echizen Province was prosperous during the Edo period, being ruled by the Echizen Matsudaira clan, a direct retainer of Tokugawa clan who ruled the Edo government. Many skilled swordsmiths moved to Echizen from different regions because of high demand among Samurai who lived there.

 The MINO swordsmiths style, also known as MINO-DEN, basically has the TOGARI(Pointed shapes protruding from the Hamon )in a classic straight line and random temper line with some white Utsuri. MINO-DEN had its origin from YAMATO-DEN in the late KAMAKURA period(1280-1330). It flourished in the MUROMACHI period(1333-1573) and continued until the EDO period(1603-1868).

 MINO-DEN especially prospered during Sengoku Jidai(Warring State period) due to the high demand for weapons. And the location of Mino province beat others. Akechi Mitsuhide controlled Mino province, and Nobunaga Oda ruled Owari province, and Tokugawa Ieyasu was the lord of Suruga (Neighboring areas). There was high demand from those powerful feudal lords and their retainers. Furthermore, so many wars occurred between the Kanto region and the Kyoto area, and Mino is located in the middle, making feudal lords feel convenient to order swords from MINO-DEN. The blades forged in MINO provinces also had the reputation of their practical design and sharpness. Many feudal lords demanded swords forged in the Mino province. Also, many swordsmiths in Mino province moved to other areas of Japan like Echizen Seki swordsmiths by being hired by feudal lords.

*Please keep in mind that there are a couple of visible Kitae Kizu on the Wakizashi.

What is Daisho?

 Daisho is a pair of two Japanese swords Samurai carried. During the Edo period, having Daisho in public places was considered social status for Samurai. Furthermore, Samurai were required to wear them under the law back then. Daisho is written as 大=Big and 小=Small. Dai part means Katana, and Sho part means Wakizashi. They have such a fancy appearance that we believe a high-ranked Samurai owned them. We are confident you would like this pair of Daisho Koshirae. And based on the style of the sword mounting, they are categorized as DENCHU KOSHIRAE(Sword mountings for entering a castle), which is very formal style of the mountings.


This Katana blade is appraised as a Tokubetsu Hozon Token(特別保存刀剣) and this Wakizashi is appraised as a Hozon Token (保存刀剣). They were issued by NBTHK(Nihon Bijutsu Touken Hozon Kyokai:日本美術刀剣保存協会). These authentication papers were only given to authentic Japanese swords well preserved and high quality with artistic value.

NakagoNakago 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(Sabbard), Tsuka( Handle), Tsuba(Handguard).

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

 This Fuchi Kashira has a simple look. The Kashira part is made of buffalo horn and colored with black lacquer. On the other hand, the Fuchi part is decorated with the Nanako-Ji (魚子地) technique. By striking with a Nanako-Ji Tagane (魚子地鏨, a chisel uniquely used for this process), uniform unevennesses were created on the surface.

 There is a Koshirae named the Ban Zashi (番指), which is also called the Kamishimo Zashi (裃指) or the Denchu Zashi (殿中指). About its alias Denchu Zashi, the word Denchu (殿中) refers to the Shogun (将軍, General)’s residence. When entering the castle, Samurai left their Daito (大刀, long sword; Katana) at the entrance and carried only short swords. They inserted their swords in such a way that they could not cut the opponent at the same time as the sword was drawn.

 We believe this Daisho Koshirae could be categorized as the Ban Zashi Koshirae. The handle is wrapped with stingray skin, and Menuki is often made from luxurious materials such as gold. In this style of Koshirae, the scabbard has finished with black lacquer. Furthermore, the Fuchi Kashira also matches the one used in this Ban Zashi Koshirae’s construction.

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

 The motifs of these Menukis are Samurai-related tools. One side is the Yari (槍, spear), and the other side is the Hata Jirushi (旗印, banner). The Yari is once one of the primary weapons for Samurai warriors. A spear has a long, thin handle, and a sword is attached to the tip. As the battle format shifted from cavalry battles to foot battles and from individual battles to team battles, spears came to be used more than Naginata (薙刀, different type of long weapon) and widespread.

 The Hatajirushi is a military flag used on battlefields. The Hata Jirushis reflected the thoughts and worldviews of military commanders; therefore, there were various designs for Hata Jirushis. In this work, we can see that horizontal stripes are drawn on the top of the flag. Although it has now peeled off due to aging, we estimate that these flags were initially painted in gold and silver.

Tsuba and HabakiTsuba 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. 

 These Tsubas have the Kikuka (菊花, chrysanthemum flower) shape. The whole forms imitate chrysanthemum petals, and a leaf is engraved on each side. It is a stylish composition in which a part of the leaf is superimposed on the flower. It seems both Tsubas are made from iron. You could enjoy the color and texture of iron that has passed the long years. This flower design is often seen in sword mountings. A long time ago, the chrysanthemum was used as a medicine for obtaining a long life in the continent, and it was brought to Japan with this thought in the Nara period (648-781). The chrysanthemum symbolizes autumn, and people have greatly appreciated it since ancient times. As its petals form radially, the chrysanthemum has been likened to the sun. That is why this flower pattern is treated as the symbol of perpetual youth and longevity or good health.

Saya Saya is the scabbard for the Japanese sword.  

 These scabbards are colored with elegant black lacquer. You would find golden circle-shaped marks on these scabbards, and all of them are the same pattern. We believe this design is a family crest called the Sagari-Fuji (下り藤). It is a kind of Fuji (藤, wisteria) pattern. Since wisterias have strong fertility and grow being entwined with other trees, people regarded this flower as a symbol of longevity and prosperity for future generations.

 Also, its Japanese name Fuji (藤), is likened to another word Fushi (不死), which means immortality. According to a theory, that is why the Fujiwara (藤原) family, who reached the height of glory in the Heian period (794-1185), used this motif for their family name and family crest. It is said there were Samurai families who used Fuji-designed family crests due to the admiration of the Fujiwara clan, which once occupied most of the upper aristocrats. Also, it might be because they wanted to share the prosperity of the Fujiwara clan. This trend possibly influenced the Sagari-Fuji pattern of these scabbards.

KozukaKozuka is a small knife stored in Kozuka Hitsu (groove of the sheath of the Japanese sword).
