Antique Japanese Sword Wakizashi Attributed to Mino Senjuin with NBTHK Hozon Certificate
This blade is attributed to Mino Senjuin (美濃千手院), which is one of the most famous schools during the late Nanbokucho-late Muromachi (Mid 14th-Early 16th century) period in Mino province (today’s Gifu prefecture). According to NBTHK that appraised this blade, it was approximately made during the mid-late Muromachi period (Late 15th-Early 16th century).
The school was located in Akasaka village near Sekigahara, an essential hub for transportation and military bases from ancient times. It is said that the Mino Senjuin school was founded by Sensui (泉水), the son of Yamato Koku Senjuin Shigehiro. Yamato region was one of the most famous sites for sword-forging during the late Heian-Kamakura period. Sensui moved from Yamato (today’s Nara prefecture) to Akasaka village in Mino province during the Nanbokucho period.
Senjuin School in Yamato region
There was a temple called Senjudo in Nara prefecture where Senju Kannon (Thousand arms) Budha statue was worshiped. And a group of swordsmiths who lived there was known as Senjuin (千手院). They belonged to Todaji temple. Senjuin School was founded by Yukinobu, who was the son of Yoshiyuki. Yukinonobu was originally a servant for Senjuin temple, a branch of Todaiji temple during the late Heian period (1086-1107), and eventually became an Okakae Kaji for the temple.
A dragon is beautifully engraved on one side. Initially, the dragon was an imaginary creature found in ancient foreign traditions or myths. Furthermore, it is regarded as a symbol 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 the Mizuchi (蛟, a mythical animal in Japan that looks like a snake and has 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.
This blade is appraised as a Hozon Token(保存刀剣) issued by NBTHK(Nihon Bijutsu Touken Hozon Kyokai:日本美術刀剣保存協会). This authentication paper was only given to authentic Japanese swords, well preserved with artistic value.
*Please keep in mind that there are a couple of black rusts and Kitae Kizu on this blade while they don’t tarnish its beauty. If you like to know the detailed condition, please feel free to contact us.

Horimono : Engraving on the blade
Nakago：Nakago is the tang of the Japanese sword.
Japanese swordsmiths left the black rust on the tang on purpose to prevent red rust while the tang is in its handle. And the discoloration of the tang was created over time, which 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).
Fuchi-Kashira：A pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.
We think this Fuchi Kashira’s motif is related to the Menuki, which we will mention later. On the Fuchi part, various types of seashells are designed. Also, seashells and ropes are engraved on the Kashira part. Several shells are colored with golden paint.
In Japan, there is a classical pattern called the Kaidukushi (貝尽くし). It is a combination of different types of seashells and is often designed with a seaside scene or wave pattern. You would feel the refreshing atmosphere of summer. Bivalves, especially clams, their shells cannot be combined with any other clam’s frame; therefore, it is believed that its pattern represents happy marriage.
Tsuka and Menuki：Tsuka is the handle of the Japanese sword and Menuki is its decoration.
As mentioned above, we guess this Menuki’s motif is also seashells. The figure of many seashells collected on a basket is designed. It seems it was initially decorated with golden and brown colors. Seashell is called Kai (貝) in Japanese. Because of its pronunciation, the seashell has another meaning. There is a word Yarigai (やりがい, worthwhile). As a part of this word has the same accent as Kai (貝 is read as Gai in some cases), Japanese people found this meaning. Also, since seashells are hard and combined only with their pair, people thought it represented a robust defense. Due to these meanings that inspire warriors who go to the battlefields, Samurai might have loved this motif.
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 has Kozuka and Kougai holes. As ornamental colorings (such as gold or silver) are not applied to this Tsuba, you could enjoy its material color directly. And it shows us its antique texture from its surface touch.
We are unsure about the motif, but we guess its symmetrical shape seems like a key or lock. The Kagi (鍵, key) motif has been appreciated in Japan since ancient times. Keys were often used to lock warehouse doors. That is, keys were treated as items to protect treasures. Therefore, people have treated the key design as an auspicious pattern. This motif is also included in the Takaradukushi (宝尽くし) pattern.
Saya： Saya is the scabbard for the Japanese sword.
Authentication Paper：NBTHK Hozon Certificate for the blade (No. 3028111)
NBTHK, also known as Nihon Bijutsu Touken Hozon Kyokai (the Society for the Preservation of the Japan Art Sword), is one of the oldest Japanese sword appraising organizations in modern-day Japan.
