Antique Japanese Sword Katana attributed to Musashi Daijo Fujiwara Tadahiro with NBTHK Hozon Certificate


 This blade is attributed to Musashi Daijo Fujiwara Tadahiro (武蔵大掾藤原忠広). This maker’s name was used by the first-gen Tadayoshi in his career.  Hizenkoku is the province’s name in today’s Saga prefecture on Kyushu island. The first-gen Tadayoshi is considered one of the most renowned swordsmiths during the early Edo period. Also, the maker’s name, Tadayoshi, lasted many generations throughout the Edo period.

 He was born in the third year of the Genki era (1572: Late Muromachi period) as the son of Hashimoto Michihiro. Tadayoshi’s birthname was Hashimoto Shinzaemon. It is said that Hashimoto family had Samurai lineage and served Ryuzoji Daimyo (feudal lord) as a retainer for generations on Kyushu island. However, in 1584, his grandfather Morihiro and Father Michihiro were killed in a war called Okinawa-te no Tatakai, where Ryuzoji clan fought against Shimazu clan. Therefore, Hashimoto family couldn’t keep serving the clan and status of Samurai because Tadayoshi, the head of the family, was just 13 years old.

  The whole family turned the new leaf. Tadayoshi was supported by Dotanuki Zenbei, who was related to Tadayoshi and had served Kato Kiyomasa, a legendary warlord during Sengoku Jidai (Warring state period). It is said that he learned sword-forging techniques from Zenbei for about 13 years.

  In 1596, under the domain’s order, he went to Kyoto to learn the sword-forging techniques from Umetada Myojyu(埋忠明寿), one of the greatest swordsmiths in the early Edo period. Tadayoshi improved his craftsmanship and returned to the Saga domain three years later (1598). The first head of the Nabeshima clan, Nabeshima Katsushige, appreciated the work of the first-gen Tadayoshi very much. Then, Katsushige appointed him as his Okakaekaji, a swordsmith who exclusively forged swords for a specific domain or clan. And Tadayoshi started to stay near Saga castle, which was the headquarter of the Nabeshima clan. Then, he founded his school, which trained more than 100 swordsmiths during the Edo period. His outstanding skills were passed to the generations of Tadayoshi and among apprentices.

 According to available records, the earliest work he signed his signature with the year is the 5th year of the Keicho era (1600), when he was 29 years old. Interestingly, he revisited Kyoto in the 10th year of the Genwa era (1624) and received an honorable official title of Musashi Daijyo on Feb 18th from the emperor for his excellent craftsmanship. And, he changed his name to Tadahiro. He made 4 different signatures during his career. They are  Hizen Koku Shinzaemonnojo Tadayoshi , Hizen Koku Junin Tadayoshi, Hizen Koku Jyu Fujiwara Tadayoshi and Musashi Daijyo Tadahiro. He was active in sword-forging for about 30 years. And he died in the 9th year of the Kanei era (1632).  

 The swordsmiths in the Hizen province worked under the auspices of the Nabeshima clan like Tadayoshi. They could produce beautiful blades with Konuka Hada, whose steel surface is very smooth. This Hada is one of the most well-known characteristics of the blades produced in Hizen province. The swordsmiths also used and mixed carbon steel made in western countries. Since Hizenkoku had been flourishing through international trading, it had easy access to western carbon steel.


 This blade is appraised as a Hozon Touken (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, well preserved and high quality with artistic value. 


Please keep in mind that there are a couple of black rust on the Mune (backbone) of  this blade. If you like to see the detailed condition before placing an order, please make sure to ask us to send you additional photos first.


Cutting Edge Length (Nagasa): 71.8 cm ( 28.2 inches)
Curvature (Sori): 1.4 cm (0.55 inches)

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.

 Since the surface is worn due to aging, it is challenging to judge the detailed design: we think a rabbit is engraved on the Kashira part. The Kanji letter for a rabbit is written as “兎” in Japanese. Since the shape of this character is similar to the Kanji “免 (it means avoid),” it is said that this animal design wards off bad luck and misfortune. In addition, rabbits have high reproductive ability, so it is a symbol of offspring prosperity and safe delivery. And the figure of a rabbit jumping forward is a symbol of “things will be solved without problems.” This animal is closely related to the moon, as there is the idea that there is a rabbit on the moon.

 There is an idea that there are rabbits on the moon. The moon is read as “Tsuki (月),” and the expression “ツキがある (Tsuki-ga-aru),” which means “having luck,” could be found. This is also one of the reasons why rabbits have been treated as auspicious existences.

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

 The same as the Fuchi Kashira we focused on above, this Menuki is also challenging to distinguish this Meunki’s motifs. We could find a figure of an animal with curly hair at the lower side Menuki. And we assume it is probably a Karajishi (唐獅子). The Shishi (獅子) means a lion in Japanese, and the Karajishi is a lion brought from the Continent to Japan in the Toh period (唐, Tang dynasty, 618-907). Karajishis typically have curly hair for their head, neck, body, and tail. In Buddhism, the Karajishi is regarded as a symbol of wisdom, and the Monju Bosatu (文殊菩薩, Manjushri Bodhisattva) rides lions. According to a theory, the Kara-Jishi originates from the Komainu (狛犬, stone guardian dogs that exorcize evil spirits).

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. 

 We estimate this Tsuba’s design is a combination of the motifs related to the Fujin (風神) and the Raijin (雷神). Although the gods themselves are not directly depicted, their symbolic tools are expressed in this work. According to Japanese myths, the Fujin controls the wind, and the Raijin controls thunder. Especially in Buddhist art, these two gods are depicted as a pair of beings. The Fujin creates a big wind from the Kazabukuro (風袋, a sac which the Fujin carries on his back) and blows it to the ground. And the Raijin rings drums on his back and causes thunder. Japan has been agriculturally advanced since ancient times. Even before Buddhism was introduced to this country from the continent, they prayed to the Fujin to calm storms or typhoons because these natural disasters caused significant damage to crops. Fujin festivals to soothe the wrath of the gods have been held in various places. This belief might have inspired this Tsuba’s design.


Saya: Saya is the scabbard for the Japanese sword.  

Authentication Paper: NBTHK Hozon Certificate for the blade (No.3012915)
