Antique Japanese Sword Katana Signed by Suketsugu with Tokubetsu Hozon Certificate 【Description】 Summary 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. Yamato Region 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. 【 Blade】 Cutting Edge Length(Nagasa) : 70.9 cm (27.9 inches) Curvature(Sori) : 2.8 cm ( 1.10 inches) Hamon : The crystalline structure which forms along the cutting edge of a blade as a result of the hardening process Jimon(Jihada) : visible steel surface pattern created by folding and hammering during forging process 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 gorgeo
