Antique Japanese Sword Katana attributed to Kozori with Tokubetsu Hozon Certificate
【Description】
Summary
This blade is attributed to a Kozori swordsmith during the late Nanbokucho Period (the late 14th century). Kozori is a group of swordsmiths who belonged to the prestigious school in Bizen (備前, the area located in today’s Okayama prefecture), called Osafune school during the Nanbokucho period but weren’t part of major branches such as Kanemitsu school. In this school, Moromitsu, who was also active in the Nanbokucho period, is one of the most prominent figures. Other famous swordsmiths seen as Kozori are Morimitsu (His son), Yasumitsu. The three swordsmiths, Moromitsu, Morimitsu and Yasumitsu are called O-Ei no Sanmitsu (応永の三光), three most renowned swordsmiths in Kozori school during the O-Ei era (the late 14 – the early 15th century).
When Kozori swordsmiths were active in the Nanbokucho period, Japan was tumultuous because the imperial court was split into two sides (south and north). There were many conflicts, and many Samurai were deployed. And Kozori school must have dedicated themselves to forging high-quality blades for those Samurai who fought in battles.
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. Their names are Nagamitsu, Kanemitsu, 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.
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.

【 Blade】
Cutting Edge Length(Nagasa):70.1 cm (27.5 inches)
Curvature(Sori):1.3 cm (0.51 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
Kissaki:Kissaki is the tip of the Japanese sword.
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.
Some kind of bird and plants are designed on this Fuchi, and golden waves and bubbles are designed on this Kashira.
As waves’ movements continue endlessly, the wave pattern represents eternity, immortality, longevity, birth, etcetera. Also, since tides repeatedly change the shape and terrain of rocks, some people hoped for a strong will by using this motif. People used this pattern wishing for an indomitable spirit to rechallenge time and time without giving up. Thanks to its dynamic design, this motif has been appreciated, especially for men’s Kimono (traditional Japanese costume).
Also, the surface of this Tsuba is finished with the Nanako-Ji (魚子地) technique. By hitting with the Nanako-Ji Tagane (魚子地鏨, chisel used for this technique), delicate fish egg-shaped protrusions are made on the surface of the metal. This process is often seen and is one of the elements that add gorgeousness to the appearance of metalworks.
Tsuka and Menuki:Tsuka is the handle of the Japanese sword and Menuki is its decoration.
It is challenging to judge the motif of its design, but we assume the motif is probably some tools for Samurai warriors. Golden paint is partly applied to this work.
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.
The motif of this Tsuba is a combination of pine trees (松, Matsu), bamboos (竹, Take), and cranes (鶴, Tsuru), which is called the Sho Chiku Kaku Zu (松竹鶴図) and they all are regarded as good omen motifs. The surface of this Tsuba is also finished with the Nanako-Ji (魚子地) technique.
As pine trees keep their green color throughout the years by withstanding severe heat and cold, people thought this plant pattern represents eternal youth. Furthermore, its color is called Tokiwa-Iro (常盤色, evergreen trees’ dark green color with brown), and pine trees have another name “Tokiwa-Gi (常盤木).” Tokiwa means immutability, so Tokiwa-Iro is a color that praises green with a wish for longevity and prosperity. It is said this color was appreciated, especially in the Edo period, as a good-luck color. The pine tree design gives us an elegant and noble impression; it might be another reason that people love this motif.
Bamboos grow neatly towards the sky, and it is vital so that this motif represents nobility and strength. Besides, the bamboo breaks straight, but its content is hollow; people thought it shows innocence. According to a Chinese legend, Houhou (鳳凰, Fenghuang) eats bamboo fruits; therefore, bamboo has been considered a sacred plant. Also, as it keeps its green color even in cold winter, people thought the bamboo pattern shows eternity and longevity. We would say that the bamboo pattern is one of the familiar designs for Japanese people since ancient times.
As for cranes, there is a proverb that says cranes and turtles live a long life. It says cranes have even one thousand years lifespan; therefore, cranes have been considered as the symbol of longevity since a long time ago. Also, as cranes make compatible couples, its pattern represents happy marriage. Due to its pure white feathers and dignified appearance, it was favorably used as a good omen design for various ornaments or furnishings such as Kimono (着物, traditional Japanese costume) or Obi (帯, belt for Kimono). Senbazuru (千羽鶴, thousand cranes) is one of Japan’s most popular Origami craft, which is made of Origami paper. A thousand cranes of paper are jointed, and it is mainly used for wishes of recovering.
Saya:Saya is the scabbard for the Japanese sword.
Some plant pattern similar to the Karakusa (唐草, arabesque) is designed on this Kojiri (the head of the Saya). The Karakusa design is a pattern in which vine stems and leaves are twined and make curves. Since ivy has a strong vitality and grows without interruption, people regarded this design as a symbol of prosperity and longevity.
Authentication Paper:NBTHK TOKUBETSU Hozon Certificate for the blade (No. 1002448)
