Antique Japanese Sword Katana Attributed to Nagamori with NBTHK JUYO TOKEN Certificate
This blade is attributed to Bizen Osafune Nagamori (備前長船長守), who was active during the mid-Nanbokucho period (Mid 14th century: Approx. 650 years ago). Based on the blade’s characteristics and available records, NBTHK attributed it to Nagamori, while there is no signature due to Suriage, a Japanese sword terminology to describe shortened blades.
He belonged to Bizen Osafune school (headquarter) in today’s Okayama prefecture. Among many branches, he worked for Chogi (Nagayoshi) school run by his father named Nagayoshi. Nagamori is one of the most prominent figures during the Nanbokucho period in Bizen province. He was a direct descendant of the founder of Bizen Osafune school.
About Chogi (His father)
Chogi was the son of Mitsunaga (光長), whose grandfather was the founder of Bizen Osafune school (Mitsutada). Mitsunaga’s father was Sanenaga (真長). Chogi is known as one of 10 apprentices of Soshu Masamune (相州正宗), a renowned swordsmith in Japanese history. Masamune was a master of SOSHU DEN, one of the five traditions of Japanese sword forging. Bizen province was also famous for its unique sword forging tradition, BIZEN DEN.
It is said that Chogi mastered the unique Japanese sword-forging technique called Soden Bizen, which is the combination of SOSHU Den and BIZEN DEN. The swords forged in Soden Bizen were very popular among Samurai back then. His son, Nagamori, also mastered this high level of this craftsmanship from his father. And, Nagamori was surrounded by prominent figures, growing up to become a great swordsmith.
This History of Bizen Osafune School
It is said that Osafune school was founded by Mitsutada (光忠), who was active during the mid-Kamakura period. Bizen Osafune school was the biggest one of all other schools in Bizen province, and they received many orders from feudal lords or renowned Samurai. They were called Osafunemono and beloved by Samurai warriors.
Among the swordsmiths who belonged to this school, Nagamitsu, Sanenaga, and Kagemitsu are known as Osafune Sansaku, the three renowned Osafune swordsmiths. There are also four other prominent swordsmiths who were from Bizen Osafune school. They are called Osafune Shiten-no, the four masters of Osafune school. They are Nagamitsu, Kanemitsu, Chogi (Nagayoshi), and Motoshige.
BIZEN is located near the Chugoku Mountains, where iron sands, one of the essential materials for making Japanese swords, were abundant. Furthermore, BIZEN swordsmiths had close access to Yoshi River, where they could find water and charcoal. This geological location contributed to the swordsmiths forging high-quality refined blades. We presume BIZEN was quite active in sword-forging from ancient times. It is said that BIZEN DEN was created by groups of swordsmiths there during the late Heian era (Late 12th century ). These ancient swordsmiths in Bizen province are called Ko-Bizen (Old Bizen) swordsmiths. By inheriting the sword forging techniques from Ko-Bizen swordsmiths, the Bizen Osafune school flourished from the mid-Kamakura period.
This blade is appraised as a JUYO TOKEN(重要刀剣) 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, exceptionally well preserved and of high quality with artistic value. JUYO is one rank higher than Tokubetsu Hozon. To be eligible for a Juyo Token, it needs to be appraised as a Tokubetsu Hozon Token first. It is extremely rare for an antique Japanese sword to be appraised as JUYO TOKEN, and it is highly desirable among Japanese sword collectors.

Curvature(Sori)：1.6 cm( 0.62 inches)

Nakago：Nakago is the tang of the Japanese sword.
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.
On the Fuchi part, you would find a geometric pattern. Although engraved lines are a little hard to see due to wear and aging, we think this design is categorized as the Saya Gata (紗綾形) pattern. It is a type of continuous design, and many Samurais loved it. According to a theory, this motif was brought from a foreign country to Japan in the Momoyama period (1568-1600). The Saya Gata pattern has a graceful appearance and represents the longevity and prosperity of the family. On the Kashira part, you would find a wood-grain tone pattern. Same as the Fuchi part, here is also decorated with golden inlay (estimated brass inlay).
Tsuka and Menuki：Tsuka is the handle of the Japanese sword and Menuki is its decoration.
A kind of plant is the motif of this Menuki. You would see small fruits and leaves. We are unsure what it is; however, we guess it might be the Nanten (南天, nandina) or the Donguri (団栗, acorn). People have regarded the nandina as an auspicious plant since ancient times. Its Japanese name Nanten has the same pronunciation as the word Nanten (難転); Nan-ga Tenjiru (難が転じる). It means “change misfortune to good fortune.” Based on this wordplay, it is said many Japanese people grew this plant believing it would protect them from fire or evil spirits in the Edo period.
According to a theory, there is an idea that the acorn is the symbol of life, fertility, and eternal life In Northern Europe. Although it is uncertain if a similar idea existed in Japan at that time, possibly people regarded it as a good-luck item. In addition, the Kuri (栗, chestnut), which is similar to an acorn, was also incorporated into the sword mounting motif. There is a variation of the chestnut motif: the Kachi-Guri (搗栗, dried chestnuts). As its name, Kachi-Guri has the same pronunciation as a Japanese word: Kachi (勝ち, victory). We imagine Samurais appreciated it as a good-luck omen to hope the success in battles. The former owner of this Katana might have wished some of its good luck would come to him.
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. This Tsuba has a symmetrical design; almost the same shape patterns are evenly arranged. It is challenging to judge the origin of this pattern, but here we would like to introduce a possibility. Wild geese are migratory birds that represent fall. This bird is designed not only as a realistic figure but also as a very simplified shape: Hiragana (ひらがな, a kind of Japanese letter) “he (へ)” shape that sometimes makes also wild goose.
Saya： Saya is the scabbard for the Japanese sword.
Authentication Paper：NBTHK JUYO TOKEN Certificate for the blade (No. 6095)
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. They authenticated the blade on Nov 1st in the 52nd year of Showa (1977). They appraised it as JUYO TOKEN, the blade exceptionally worth preserving for Japanese society. The purchaser will receive this original certificate as well. We can also translate what is written into English and make a PDF file for your record if you request.
