Antique Japanese Sword Katana Signed by Suketsugu with Tokubetsu Hozon Certificate
This blade was signed by Suketsugu (助次), who was active during the early Muromachi period (1394-1429) in Yamato province (today’s Nara prefecture). It is said that he belonged to Senjuin school and served Toudaiji temple. Senjuin school is the oldest school among other schools that flourished during the Kamakura-Muromachi 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, another famous swordsmith. Yukinonobu was originally a servant for Senjuin temple, a branch of Todaiji temple during the late Heian period (1086-1107), and eventually became a swordsmith who exclusively forged blades for Todaiji temple.
There were five prestigious schools, including Senjuin school, during the Kamakura-early Muromachi period in Yamato province. They are called Yamato Goha(大和五派); Senjuin(千手院), Shikkake (尻懸), Taima(当麻), Hosho(保昌) and Tegai(手掻) school. They served politically powerful monks and temples in Nara, such as Todaiji temples. They were initially forging swords for military monks who became powerful due to the government’s policy back then.
Monks needed many weapons as there were many political rivalries between influential temples. They required strong weapons like swords to protect themselves. During this time, Senjuin school or other Yamato sword schools met the requests from monks. They also forged blades for Samurai during their heyday.
The swords forged in Yamato regions are famous for their beautiful Jigane, steel surface, and straight tempering line(Suguha). This blade has a beautiful Jigane with a Suguha tempering line, which shows an outstanding characteristic of the Yamato sword.
Ubu Nakago (生茎)
Ubu Nakago is a Japanese sword terminology that refers to a blade that hasn’t been shortened. This blade has a cutting edge length of 70.9 cm. It is Ubu Nakago, meaning it was never shortened since its creation. It was common for Samurai to have their Katana shortened to follow the imposed regulations or adjust their body size. You can often see the shortened blades made during the Kamakura-Muromachi period. However, the length of this blade hasn’t changed, and it is extremely rare to find such a piece (Ubunakago) made before the Edo period and its signature still remains on the tang.
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.
*Please keep in mind that there are a couple of Kitae Kizu on this blade. If you like see the detailed condition, please feel free to contact us.

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. On the other hand, the Fuchi part is gorgeously decorated. It has a rough surface, and you will find minor golden marks. These are the family crests called the Go San-no Kiri (五三の桐) pattern. The number of flowers blooming at each inflorescence means the ranks of this design. It is a popular design that the paulownia (this flower is called 桐 in Japanese) 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.
Tsuka and Menuki：Tsuka is the handle of the Japanese sword and Menuki is its decoration.
We can see the figure of a dragon on this Menuki. In addition, we can also see golden ring patterns and stripes. Although we cannot see the entire shape of this Menuki, we estimate its motif is a combination of dragon and tiger. Both animals’ designs were favored among Samurai warriors. 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, the 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.
The tiger is a brave animal. A theory says people considered the tiger pattern would protect people from evil spirits. Therefore, its pattern has been treated as a talisman. The combination of these beasts is called the Ryu Ko Zu (龍虎図), a design that expresses the fighting spirit of those with the same power fighting fiercely. This idea might have inspired this Menuki’s design.
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 a unique symmetrical shape. You would find four heart marks on each end. This is the Inome (猪の目, boar’s eyes) pattern, which has been used since ancient times. Some people believed that the Inome design would work as an amulet to protect them from evil spirits or fire. Also, it is said it would bring good luck. This pattern is often found in traditional Japanese architectures such as shrines or temples and used Gegyo (懸魚, decoration under the roof, where the roof is jointed) or metal fittings for hiding timber joints. Such a religious motif was sometimes incorporated into sword mounting designs.
Saya： Saya is the scabbard for the Japanese sword.
Authentication Paper：NBTHK TOKUBETSU Hozon Certificate for the blade (No. 1014490)
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.
