Antique Japanese Sword Tachi Unsigned Nioh with NBTHK Tokubetsu Hozon Certificate 


According to NBTHK that authenticated the blade, it was forged by one of Nioh’s swordsmiths. Although the authentication paper doesn’t say when it was made, we contacted NBTHK to confirm its age. They believe it was created during the late Kamakura period(about 700 years old) based on the blade’s characteristics. This school mastered superb craftsmanship, and it is known as one of the most famous schools in this region.

Nioh is the group of swordsmiths(school) that flourished from the mid-Kamakura period to the late Muromachi period(500-750 years ago) and lasted until the Edo period(150—400 years ago).

The school was founded by Nioh Taro Kiyotsuna(二王太郎清綱) in Suo Province(today’s Yamaguchi prefecture). According to his remaining work, the oldest blade was forged in 1265. It is currently enshrined in Itsukushima Shrine in Hiroshima. It is said that he started to forge swords in around 1205(early Kamakura period). The Nioh swordsmiths inherited the part of its founder’s name 清(Kiyo) such as 清房(Kiyofusa), 清長(Kiyonaga).

There were a lot of lands in Suo Province controlled by the Todaiji temple in the Kamakura-Muromachi period. It is said that Nioh school and Yamato swordsmiths from Nara prefecture had a strong relationship and technological exchange.
That is why the blades forged by Nioh swordsmiths had a strong influence from YAMATO-DEN.
*Todaiji temple is located in Nara prefecture. Before the Edo period, temples and shrines gained strong political influence.

The name Nioh came from the legend that the Tachi blade forged by Kiyotsuna(the founder of Nioh school) was able to save the Nioh statue by cutting the chain connected to it when Nioh temple was on fire.
Another theory was that Nioh swordsmiths lived in a village called Nioh no Sho(二保庄) and started to call themselves Nioh swordsmiths.

Considering how old it is, this blade is remarkably well preserved, and its appearance is elegant. We assume this blade might have been initially owned by the imperial lineage or one of higher authorities back then.

An incredibly beautiful Koshirae(sword mounting) is also worth mentioning. It is categorized as Tachi koshirae(Horseback style). This Koshirae was also authenticated as Tokubetsu Kicho Item(Rare Special Item) by NBTHK. The Koshirae is newer than the blade, but this mounting’s delicacy is aesthetically pleasing to look at.

This blade is appraised as Tokubetsu Hozon certificate issued by NBTHK. This authentication paper was only given to Japanese swords, especially worth preserving by Nihon Bijutsu Touken Hozon Kyokai(the Society for the Preservation of the Japan Art Sword).

NakagoNakago is the tang of the Japanese sword.

 We believe this blade was shortened at least once based on the two Nakago holes. 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 Gosan-no Kiri (五三の桐) and chrysanthemum patterns are arranged alternately. The Kiri (桐, paulownia) pattern is composed of three standing straight inflorescences and three leaves. The number of flowers that are blooming at each inflorescence means the ranks of this design. For example, the Goshichi-no Kiri (五七の桐) pattern has five-seven-five flowers for inflorescences. So that this is a more high-ranked design than Gosan-no Kiri (three-five-three flowers) pattern, this motif is known as the symbolic design of the Japanese government. It is also famous that one of the most popular Samurais in Japan: Toyotomi Hideyoshi used the Kiri pattern for his family crest. This plant pattern was once used by the imperial family and national leaders of the time. However, today, it is often used by ordinary people.
Tsuka and MenukiTsuka is the handle of the Japanese sword and Menuki is its decoration.

 A chrysanthemum is sandwiched between two paulownias. The same motifs unify this sword’s mountings.

 A long time ago, the chrysanthemum was used as a medicine for obtaining a long life in China, and it was brought to Japan with this thought in the Nara period (648-781). Chrysanthemum is one of the flowers which symbolizes fall, and people appreciate it very much since ancient times. As its petals form radially, the chrysanthemum has been likened to the sun. That is why this flower pattern is treated as the symbol of perpetual youth and longevity or good health.

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 Tsuba is decorated with common plant motifs as well as Fuchi Kashira and Menuki. The decoration remains in good condition, and the contrast of black and gold colors gives us a noble impression. You would find heart marks at four corners and top, bottom, right and left. This design is called Inome (猪の目) patten in Japanese and is often seen in architecture in shrines or temples. This pattern is used for a long time. Its name comes from the eyes of boar. Some people believed that the Inome would work as an amulet to protect them from evil spirits or fire. Also, it is said it would bring good luck.  

Saya Saya is the scabbard for the Japanese sword.  

Authentication PaperNBTHK TOKUBETSU Hozon Certificate for the blade, Tokubetsu Kicho Certificate for the Koshirae

 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 Aug 6th in the 10th year of Heisei (1998). They appraised it as Tokubetsu Hozon Touken, the blade especially worth preserving for Japanese society.

Its Koshirae(Sword mounitng) was appraised as Tokubetsu Kicho by NBTHK on Sep 20th in the 45th year of Showa (1970). The last part is blurred out because its owner’s name back then is written.

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.
