Antique Japanese Sword Katana Signed by Motohira with Tokubetsu Hozon Certificate 


 This blade was signed by Oku Yamato no Kami Taira Ason Motohira (奥大和守平朝臣元平) in the third year of the Kyowa era (1803). Motohira is one of the most renowned swordsmiths in Satsuma domain (Today’s Kagoshima prefecture) during the late Edo period. Oku Yamato no Kami and Ason are titles given to him in his career for his excellent craftsmanship.

 He was born in October, the first year of the Enkyo era (1744), as the first son of Oku Motonao in Satsuma domain. His birth name was Oku Kouzaemon. It was often the case with many swordsmiths that they used different makers’ names from their real names.

 In his early career, he learned sword-forging techniques from his father, and when he was 38 years old, he became a Hanko (藩工), who exclusively forged swords for a specific clan. This fact suggests that his craftsmanship was widely recognized in the domain. Furthermore, he received Yamato no Kami in the first year of the Kansei era (1789). Kami is an honorable official title given by the emperor to highly skilled swordsmiths. It is said that he trained many swordsmiths, including Bizen Sukehira. Many of his apprentices traveled to Satsuma domain from a very long distance. We assume his sword-forging techniques were very refined and appreciated among Japanese swordsmiths. Motohira was great at forging blades in Soshu Den tradition.

 Considering when he was born, this blade was forged in his late 50s. He lived a long life, and he died at the age of 84 in 1826. He kept forging blades until he was 83 years old. He must have had full of vitality to make high-quality blades throughout his career.

 Satsuma province had a high ratio of Samurai population compared to other parts of Japan. And they are famous for their military power ruled by Shimazu clan. We assume a swordsmith needed to be skilled to stay active and popular in this demanding place. Motohira was one of them. This blade has thick width and heavy weight, which would give you muscular impression on the blade. It must have been owned by a high-class Samurai who was strong enough to handle this blade.


  It is appraised as a Tokubetsu Hozon Token(特別保存刀剣) 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, especially 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(Scabbard), 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. It does not have gorgeous decorations such as gold or silver inlays. This Fuchi Kashira focuses on practicality rather than its appearance. However, we could enjoy the color and texture of the metal material more directly by seeing and touching it because there are no decorations, and above all since this sword munting is a part of the Koshirae (拵, the exterior of the sword), we assume such a simple design part was chosen to bring the Koshirae looks in a better balance.

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

 Two masks are the motifs of this Menuki. The upper side Menuki, it shapes an Otafuku (お多福) mask. Its model is the face of a short-nosed woman with round features, a protruding forehead, and swollen cheeks. Although this expression is sometimes used in a negative sense, it was considered the epitome of Japanese beauty during the Heian period. It is said that the name Otafuku (お多福, lots of happiness/good luck) came from the meaning of a woman who brings much good luck to her husband’s home. In addition, the Otafuku was initially welcomed as a good sign of good fortune. There is also the theory that he was a person who served God.

 The lower side Menuki’s motif is the Shishimai (獅子舞). This is a folk art in which people wear lion heads and dance on auspicious or festive days. Shishi (獅子) generally means a lion in Japanese. Although the name suggests a lion, the Shishi for the Shishimai is based on a mythical creature rather than a real-life lion. It was originally danced to exorcise demons, famine, and pestilence, so it means praying for and celebrating good fortune, good health, and a good harvest. According to a theory, The Shishimai was brought to Japan from the continent in 612. According to the writings of the time, at the beginning of a traditional silent performing art called Gigaku (伎楽), a Karajishi (唐獅子) dance was performed to ward off evil spirits on stage. This is said to be the beginning of the Shishimai. Since this Gigaku was rooted in Buddhism, this dance was performed on stage and in temples to purify the atmosphere. Shoutoku Taishi (聖徳太子), a famous politician at the time, also focused on Gigaku to spread Buddhism, and often had Shishimai performances at Houe (法会, gatherings for offering memorial services and preaching Buddhist teachings). It is said that this was how the Shishimai became widely known among ordinary people.

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. 

 The same as the Fuchi Kashira, this Tsuba also has a plain design. There are minor scratches and dents due to aging. We hope you would enjoy them as antique textures.

Saya Saya is the scabbard for the Japanese sword.  

This Saya is coated with stingray skin.

Authentication PaperNBTHK TOKUBETSU Hozon Certificate for the blade (No. 1002508)

  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.
