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


 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.


【 Blade】
Cutting Edge Length(Nagasa)71.1 cm (28.0 inches)
Curvature(Sori)2.2 cm ( 0.86 inches)

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.

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

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. 

 This iron Tsuba has a type of the Tomoe Mon (巴紋, Tomoe pattern). The Mimi (耳, edge) of this Tsuba is thick and has a sturdy structure. There are several theories about the origin of this design. According to an idea, it was modeled on the shape of Magatama (勾玉, comma-shaped bead), or it was based on the swirling of flowing water. The Tomoe pattern represents water, so people treated it as a talisman to prevent fire. It was often applied to the roof tiles of shrines. The design of two Magatama-shaped commas is called Futatsu-Tomoe (二つ巴), and the pattern with three commas is called Mitsu-Domoe (三つ巴). This motif also has been used for family crests.

This Habaki is made of 18-karat gold (75% Gold), which is very valuable itself, considering the soar rise in the value of gold. More details photos of this Habaki will be available on request. The weight of this Habaki is 53g.

KougaiKougai is the equipment for Samurai to arrange or fix his hair style.

 This item is an antique Kougai (笄), which was used to arrange or fix the hairstyle of Samurai. The Kougai is usually stored in the Kougai Hitsu. The Kozuka (小柄) is often stored at the other side of the scabbard.

 A Kind of plant is designed on this Kougai. We think its motif is probably the Nanten (南天, nandina). People have regarded the Nanten as an auspicious plant since ancient times. The 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 that many Japanese people grew this plant in the Edo period, believing it would protect them from fire or evil spirits. The former owner of this Katana might have wished some of its good luck would come to him.

Saya Saya is the scabbard for the Japanese sword.  

Authentication PaperNBTHK TOKUBETSU Hozon Certificate for the blade (No. 1019508)

  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 March 10th in the 5th year of Reiwa (2023). 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.
