Antique Japanese Sword Katana Attributed to Fukuoka Ichimonji with Tokubetsu Hozon Certificate 

【Description】

 This blade is attributed to Ichmonji (一文字) by NBTHK, which appraised it as a Tokubetsu Hozon Token. Ichimonji is one of the most influential schools. There are a few branches that include Ichimonji in their names. They are Fukuoka Ichimonji, Yoshioka Ichimonji, Kataoka Ichimonji and Shochu Ichimonji. Overall, more than 200 swordsmiths were categorized as members of the Ichimonji school. This fact indicates how acknowledged the schools were. We called NBTHK and confirmed that the attribution for this blade was given to Fukuoka Ichimonji school, the first Ichimonji school ever created.

 Fukuoka Ichimonji school was prosperous during the mid-Kamakura period (mid-13th century). They signed “一” (Ichi: one in Japanese) on the tang, which is the reason why they are called Ichi Monji (One Letter).

 It is said that Fukuoka Ichimonji school was founded by Norimune (則宗)in Fukuoka village in Bizen province (today’s Okayama prefecture). Many renowned swordsmiths belonged to Fukuoka Ichimonji school, including Nobufusa (信房), Muneyoshi (宗吉), Sukemune (助宗).

 Seven swordsmiths from Fukuoka Ichimichi school were selected as Gobankaji (御番鍛冶). Gobankaji is a unique system created by the retired emperor Go-Toba (後鳥羽上皇), who was enthusiastic about the preservation and development of the Japanese sword forging. He summoned thirteen of the finest swordsmiths nationwide, and one swordsmith forged a blade for the emperor each month. This fact indicates that Fukuoka Ichimonji School was highly acknowledged during that time. Norimune, the founder of Fukuoka Ichimonji school, was one of Gobankaji. Even today, 15 blades made by Fukuoka Ichimonji swordsmiths are designated as national treasures of Japan. And 7 of them are classified as Important Cultural Property.

 

 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. One of the most prominent figures in Ko-Bizen swordsmiths is Masatsune (正恒), who is said to be the father of Norimune (則宗), the founder of Fukuoka Ichimonji school. By inheriting the sword forging techniques from Ko-Bizen swordsmiths, the Fukuoka Ichimonji school flourished from the mid-Kamakura period.

 One of the most distinctive features of Fukuoka Ichimonji school is Choji Midare Hamon, which is an irregular, wavy tempering line. Because of their elegant design, the swords forged by members of the Fukuoka Ichimonji school were appreciated by high-ranking samurai.

 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 the blade. If you like to know the detailed condition, please feel free to contact us.

Cutting Edge Length(Nagasa)65.2 cm (25.6 inches)
Curvature(Sori)1.1 cm (0.43 inches)

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.

 The theme of this Fuchi Kashira is the Hatou Zu (波涛図), which depicts large undulating and splashing waves. 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). It is also said that warlords used wave patterns on their banners and armors, comparing the movement of battle to that of waves coming and going.

  

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

 The motif of this Menuki is Niwatori (鶏: rooster and hen). In ancient times, this bird was used for rituals to offer to gods. It is said this is why the chicken pattern was incorporated into family crests. As this bird tells the arrival of morning, people regard it as the Ake-no Tori (明けの鳥, bird of the dawn). Also, chickens have been treated as auspicious birds because they sing at first in the new year. In another theory, there is a wordplay: Yoikoto-wo “Tori”komu (良いことを取り込む, “take” good things). This Tori (取り) and Tori (鳥, bird) are associated based on the common pronunciation. Some people believe that this bird would bring a plentiful harvest or success in business. This Menuki design might have been chosen due to these ideas.
   

 

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. 

 On this Tsuba, three small round shapes are depicted. We assume this motif is related to the Jitsu Getsu Seishin (日月星辰, generic name for the sun, moon, stars, and sky), which has often been designed on Gunsens (軍扇, a fan used by feudal loads to take commands on battlefields and to motivate their soldiers). 日 means the sun, 月 means the moon, and 星辰 means star, constellation. 

 

Saya Saya is the scabbard for the Japanese sword.  

 This scabbard is covered with black lacquer. Due to its high waterproof effect, lacquer has been used since ancient times in Asia. The blade of a Japanese sword is made of iron, and moisture is the greatest enemy of iron. For the purpose of carrying the blade without degrading it, people devised a method of coating the scabbard with lacquer. To prevent not only moisture but also rain and snow from penetrating the inside of the scabbard, it was necessary to apply multiple layers of lacquer. The Nurushi (塗師, lacquerers) was born precisely because advanced techniques were required to handle the complicated processes.

Authentication PaperNBTHK TOKUBETSU Hozon Certificate for the blade (No. 1023005)

  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 August 23rd in the 6th year of Reiwa (2024). They appraised it as Tokubetsu Hozon Touken, the blade especially 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.

Registration Number : Kumamoto 5765

 The Board of Education in Kumamoto prefecture issued a registration paper for this sword. It is called Jyu Hou Token Rui Torokusho (銃砲刀剣類登録証). Bunkacho (The Agency for Cultural Affairs) acknowledges a Japanese sword with this paper as a work of art.
The sword needs to be traditionally hand-forged and made of Tamahagane carbon steel to be registered in the system. With this paper, its owner in Japan can legally own an authentic Japanese sword. Based on this registration number, we will apply for its export permit.
This paper will need to be returned to the board of education when the sword is being shipped abroad, but you can receive a copy of it. An English translation of this registration paper is available on request.
