Antique Japanese Sword Katana Signed by Minamoto Sukeharu with Tokubetsu Hozon Certificate
This blade was signed by Sagami No Kami Minamoto Sukeharu (相模守源祐春), who was active in Settsu province during the early Edo period (Enpo era: 1673-1681). Sukeharu is a nephew of Bizen no Kami Minamoto Sukekuni, a famous swordsmith who originally belonged to Kishu Ishido school and moved to Settsu city (Today’s Osaka). Sukekuni was the master of Sukeharu.
There aren’t many remaining works created by Sukeharu because it is said that he dedicated his career to helping his master. Sukeharu received an honorable official ranking of Sagami no Kami from the emperor for his excellent craftsmanship.
Ishido school was initially founded by Sukenaga, an offspring of Ichimonji Sukemune, who made Fukuoka Ichimonji school in Bizen province(Today’s Okayama prefecture). During 1492-1501 (Late Muromachi period), Sukenaga and his school moved from Bizen province to Omi province after being summoned by Gamou family, a powerful feudal line in that region. Sukenaga started to live in front of Ishido temple, and he changed his surname to Ishido.
Kishu＆ Osaka Ishido School
As of the early Edo period, many Ishido swordsmiths moved to other parts of Japan, looking for better opportunities. There are four areas: Edo, Osaka, Kishu(Wakayama prefecture), and Chikuzen(Fukuoka prefecture). Omi Ishido school is the origin of whole other Ishido branches that flourished during the Edo period. His master Sukekuni belonged to Kishu Ishido school but later moved to Osaka city. It is said that he played an essential role in building the foundation of Osaka Ishido school.
The blades forged by Sukeharu are categorized as Osaka Shinto. Shinto is Japanese Sword terminology that refers to the swords forged during 1596-1781. The blades made in the Osaka area during this period are called Osaka Shinto. There are many famous swordsmiths in this Osaka Shinto era. After Hideyoshi Toyotomi built Osaka castle, Osaka city flourished as a castle town and became the business center. Many swordsmiths moved to Osaka to look for better opportunities. They not only forged swords for those Samurai who lived in Osaka but also for feudal lords nationwide. Ikanshi Tadatsuna(Awataguchi Omi no Kami Tadatsuna), Inoue Shinkai, and Tsuda Sukehiro are the most famous among many swordsmiths.
One of the most notable characteristics of Osaka Shinto is its beauty in Jigane. Jigane is a visible steel surface pattern created by folding and hammering during the forging process), which made it possible by the location of Osaka. Osaka had close access to the Tamahagane(special carbon steel to make Japanese swords) production sites. The swordsmiths residing in Osaka were able to get high-quality carbon steel from these sites.
This blade 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.

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).
Fuchi-Kashira：A pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.
The Kashira part has a simple look. Although there are minor damages due to aging, its black color creates an elegant atmosphere. On the other hand, the Fuchi part has an ornamental look. Its surface is colored with golden paint and is decorated with the Nanako-Ji (魚子地) technique. About the motif, these leaves are probably Aoi (葵) because of their heart mark shapes. Today, the Aoi-Domoe / Mitsuba-Aoi-no Mon (葵巴/三つ葉葵の紋 ) is known as the family crest of the Tokugawa Shogunate family led by Tokugawa Ieyasu, a famous military commander of the Warring States period. This plant pattern has also been used for the crest of the Kamo shrine in Kyoto prefecture. As mentioned above, the famous Shogunate family, the Tokugawa family, had their family crest with three leaves of Aoi due to the relationship with the Kamo shrine. As its leaves have a habit of always facing the sun, and the word “Aoi” is taken as “Aogu (仰ぐ, looking up)” for the sun, people thought the Aoi pattern would bring good fortune.
Tsuka and Menuki：Tsuka is the handle of the Japanese sword and Menuki is its decoration.
You could find a kind of fish design in the gaps of the Tsukamaki thread. Its eyes are probably gold-colored, and you can see its adorable appearance. We think this Menuki’s motif is the Namazu (鯰, catfish). It is a fish with a large head and mouth, two beards, and a slimy body without scales. Catfishes are nervous and delicate, so they react sensitively to small shakes and violate or jump. For that reason, after the middle ages in Japan, people thought that a catfish was the cause of earthquakes because they could feel tiny shakes that nobody could realize. The catfish pattern was described often in the Edo period. There is a famous ink painting theme about this animal called the Hyoune Zu (瓢鯰図). It depicts a man trying to keep Namazu (鯰, catfish) with Hyoutan (瓢箪, gourd). It is a question and answer of Zen Buddhism. It is thought this theme came from the proverb that means to succeed having difficulty. Since the motifs of sword mountings sometimes reflect the taste of its owner or his view of religion, the former owner of this Katana with catfish might have believed in Zen Buddhism.
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.
Oval-shaped Tsuba that has Kozuka and Kougai holes. Arrows are arranged radially and make a circle shape that looks like a tire. Its design is named Yaguruma (矢車) in Japanese. Ya (矢) means an arrow, and Kuruma (車, also pronounced Guruma) means a car in Japanese. The arrow pattern has been incorporated as a talisman to protect children, especially boys, wishing them to grow up healthy and strong to become brilliant Samurai.
Since ancient times, arrows have been used as a weapon, which is the original purpose of this item. Additionally, each home displayed decorated arrows wishing it would exorcize evil spirits in the house. This talisman is called the Hama-Ya (破魔矢) in Japanese, and this custom is still kept today. As an arrow goes straight forward powerfully, lots of Samurais loved the arrow pattern.
Saya： Saya is the scabbard for the Japanese sword.
