Antique Japanese Sword Katana Attributed to Nagamitsu with NTHK Kanteisho Certificate

【Description】

 This blade is attributed to Ichiryushi Nagamitsu (一龍子 長光), according to NTHK’s appraisal. He was also known as Okayama Nagamitsu (岡山長光) and Ichihara Nagamitsu (市原/一原 長光).

 He was active in the early Showa era (around early 20th century) in Okayama prefecture. His works include the following engraved inscriptions: Nagamitsu (長光), Ichiryushi (一龍子), Ichiryushi Nagamitsu (一龍子 長光) and Ichihara Ichiryushi Nagamitsu (市原一龍子長光). He worked at Okayama Prison during the Second World War. The name of this prison director at that time was Emura Shigetarou (江村 繁太郎). There are some theories that Nagamitsu was the same person as the head of that office, Shigetarou. However, another view says they were completely different people. In any case, we cannot judge now.

 We would like to add more explanation about Nagamitsu based on the theory that he was a different person from Shigetarou. Shigetarou wished for exemplary prisoners’ rehabilitation. And he invited Nagamitsu to make the prisoners take the lead and trained many Japanese swords in the Okayama prison. Therefore, his works back then were called the Kangoku Nagamitsu (監獄長光). “Kangoku” means jail in English. However, it is said that some of the swords forged in this prison had a different inscription, such as “Emura”, so we cannot conclude that the engraved inscription “Kangoku Nagamitsu” was decided to be Nagamitsu’s work.

 Since then, he became Rikugun Jyumei Tosho (陸軍受命刀匠), which was the title given by the Japanese military to skilled Japanese swordsmiths during the Taisho – the early Showa period. To receive this title, a swordsmith forged two swords and submitted them to the governmental agency that produced weapons. After passing the particular and rigorous exam there, the swordsmith would be acknowledged as Rikugun Jyumei Tosho. We assumed he primarily forged swords for the Japanese military before and during World War Ⅱ.

KissakiKissaki is the tip of the Japanese sword.

 

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.

 Koumoris (蝙蝠, bat) and Karakusa (唐草, arabesque) pattern are depicted on this Fuchi Kashira. 

 The bats are colored with golden paint beautifully. According to a theory, the continent largely influenced the introduction of bats as a pattern. This animal is a symbol of happiness and longevity. In the continent, it was popular as an auspicious pattern that brings good luck because its Japanese name letter “蝠” and another word “福 (happiness)” have the same sound. The design depicting five bats is called the Gofuku (五福) and symbolizes longevity, wealth, health, descendants, and prosperity.

 Karakusa is a pattern in which stems and leaves of vines are twined and make curves. Since ivy has a strong vitality and grows up without interruption, people regarded this design as a symbol of prosperity and longevity. Vine is called Tsuru (蔓) in Japanese, and it has another pronunciation; “Man.” There is a word 万 (it is also read Man), which means ten thousand. In the Karakusa pattern, leaves and vines are connected like Obi (帯, belt). The word “帯” can also be read “Tai.” Due to its pronunciation, the term “代 (Tai)” is associated. From this word-association game, an idiom 万代 is associated, and it means a thousand generations. In other words, we could imagine that people used this design wishing prosperity and longevity for their clans for a long time. 

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

 We assume the motifs of this Muneki is related to the sea. The landscape patterns that depict various patterns related to the sea, such as pine trees, shells, waterfowl, and other elements on a seashore is called Kaibu Mon (海賊文). It seems that the motifs used in this Menuki are probably some seashells, pine leaves, and Nosi (熨斗).

 Noshi (熨斗) is an ornament attached to gifts and presents offered on festive occasions in Japan. In the old days, Noshi was made of dried abalones (鮑, Awabi) shaved into thin strips and stretched. There is a Ukiyoe (浮世絵, a picture of the floating world) which depicts some people making Noshi near the seashore. It was regarded as a symbol of longevity, so it was often attached to gifts for celebrations. And this type of Noshi seen on this Menuki is Tabane Noshi, also called Tsuka Noshi, which is made of several long, thin strips of Noshi that are stacked and tied together in the middle. Tabane Noshi has been a symbol of celebration and  considered to be an auspicious design which is meant not only to receive blessings from many people, but also to share the good fortune with the people around you. For this reason, this festive design was used not only for Menuki, but also for bridal costumes and so on.

   

 

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. 

 It has the shape of Yotsu-Mokkou. Its origin is the shape of eggs in a nest. When a quince (it is written 木瓜 in Japanese) is cut into round slices, its cross-section looks similar to this shape; therefore, it was named Mokkougata Tsuba (木瓜形鐔). Yotsu-Mokkougata (四ツ木瓜形, a combination of four Mokkou shapes) Tsuba is often seen, same as this Tsuba.

 Regarding the design, the shape of Hanabishi (花菱) is engraved with openwork in the up and down, left and right. In this Hanabishi pattern, petals are designed in a rhombus. This pattern became a Yusoku Monyou (有職文様, generic term for designs of court nobles’ clothing or furnishings, these designs have unique and elegant styles) during the Heian period (794-1185). People loved it as an auspicious pattern. Also, it is said that since this pattern is elegant and prestigious, it was appropriate for festive occasions such as weddings, and considered to represent longevity and prosperity of descendants.

 

 

Saya Saya is the scabbard for the Japanese sword.  

 On the surface of this Saya, it seems the feather-like pattern is depicted. Also, a part of the surface which is a close part to the Tsuba has a constant width notched pattern in the circumferential direction. This type of Saya is called the Sendan Kizami Zaya (千段刻鞘: Sendan means the 1,000 steps). 

 

Authentication PaperNTHK Kanteisho Certificate for the blade (No. 12784)

 NTHK, also known as NPO Nihon Touken Hozon Kai, is the oldest organization for sword authentication of Japanese swords in modern times. It was established in 1910 during the post-Samurai era.
