Antique Japanese Sword Katana Signed by Nagahide with Tokubetsu Hozon Certificate 


 This blade was signed by Bungo Koku Nagahide(豊後国長秀) in October in the second year of the Bunkyu era(1862 : The end of the Edo period).

 Bungo Koku is the name of the domain Masahide lived when he forged this blade. According to historical records, the swordsmith’s name Nagahide lasted three generations(1789-1868), and based on the date on the tang, we believe the third-gen Nagahide signed it.

 Generally speaking, Kyushu island was prosperous in sword-making because of the long trading history with Asian countries. To gain an advantage in trading, many feudal lords on this island fought against each other. The swordsmiths in the Bungo domain received many orders as the demand increased among those lords, especially during the warring state period(Sengoku Jidai).

 We believe the swordsmiths in this region prospered because of their geographic location and natural resources. The material of Japanese swords(high-quality iron sand and charcoal) was abundant in the mount Sobo Katamuki, located in this domain.

 After the warring state period, the fame of blades forged in the Bungo domain became nationwide during the Edo period. They were popular among Samurai for their practicality and sharpness. We assume this blade was made for a high-ranked Samurai. We can appreciate the  skilled craftsmanship of Nagahide by simply looking at it.

On the upper part of blade, we see Homare Kizu (誉疵), which tells us that this blade was used in a battle. Homare Kizu is considered a good characteristic of the blade that tells us its history.

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

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.

Homare Kizu: Kizu made during fighting. It is considered a good characteristic of the blade.


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.

 Crabs are designed on this Fuchi Kashira. As crabs walk sideways, they were compared to “Oukou Kunshi (横行君子),” which means going my way against authority. Samurais might have felt the strong mind that they would not submit to authority and stick to their own beliefs.

 If you focus on the Kashira part, you will find an animal stretching his arm and grabbing the crab. It is challenging to judge what is due to the damage to this animal’s face; it is probably a monkey. In Japan, there is a famous folktale that treats a family of crabs and a mean monkey. The outline of this story is, the monkey tricked the crab seeking only his own interests. However, this monkey was revenge by the crab and his comrades. There are some differences depending on the region, but this is the general story. This Fuchi Kashira’s design might have been quoted from this tradition. Today, it is familiar as one of the old tales to be told to small children, but the former owner of this sword might have learned some lessons from this story and chose such a design to engrave in his heart.


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

 In common with the Fuchi Kashira, this Menuki’s motif is also crabs. Two crabs are arranged side by side. It remains its glossy black color. As Japan is an island country surrounded by seas, marine life motifs have been familiar with the Japanese since ancient times. People enjoy making unique designs for various items. So, it is understandable that the crab motif is incorporated into sword mountings. 

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. 

 Yotsu-Mokkou-shaped Tsuba is made from iron. The Mokkou (木瓜) shape, its origin is a shape of eggs that are rest in a nest. When a quince (it is written 木瓜 in Japanese) is cut into round slices, its cross-section looks similar to this shape; therefore, it was named the Mokkougata Tsuba. Yotsu-Mokkougata (a combination of four Mokkou shapes) Tsuba is often seen as this Tsuba is categorized.

 Same as the Fuchi Kashira and the Menuki, crabs are designed for this Tsuba. One of them is colored with silvery metal. By using the same animal motif, the entire appearance of this sword’s Koshirae has beautiful unity.

Saya Saya is the scabbard for the Japanese sword.  

 Plants are designed for this Saya. This motif might be the Inaho (稲穂, ears of rice). Since ancient times, rice has been worshiped as an essential food and considered a symbol of wealth. In addition, it has been treated like a treasure. Some people believe the god dwells in it. Therefore, the Inaho pattern has often been designed as a crest of the Inari (稲荷) shrine, which enshrines the Inari god, who is regarded as the god of grain and agriculture. Also, this plant motif is seen for family crests. It is one of the familiar designs for Japanese people. This design might have had chosen in the hope of a plentiful harvest and a prosperous life. 

Authentication PaperNBTHK TOKUBETSU Hozon Certificate for the blade (No.1016497)

  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 27th in the third year of Reiwa (2021). 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.
