Antique Japanese Sword Katana Signed by Yasushige with Tokubetsu Hozon Certificate 


 This blade was signed by Bushu Shitahara Jyu Naiki Yasushige(武州下原住内記康重) during the early Edo Period (Mid-Late 17th century). Bushu Shitahara is the name of the area in Hachioji city in today’s Tokyo, where he created this blade.

 The maker’s name Yasushige lasted several generations from the late Muromachi period until the end of the Edo period. This blade was forged by late-gen Yasushige, active during the early Edo period. From the fourth gen, Yasushige started to inscribe Naiki in the signature.

 Yasushige belonged to Bushu Shitahara school in today’s Tokyo(Hachioji city). It is said that Yamamoto Norishige founded the school, and it thrived from the end of the Muromachi period to the late Edo period (Late 16th century to Late 19th century).

 The swordsmiths who lived in Shitahara were called Shitahara Kaji. They were the group of swordsmiths under the Hojo clan’s auspicious, powerful feudal line during the late Muromachi period first. It is said that the first-gen Yasushige was the son of Chikashige, another prominent figure in this school. The first-gen Yasushige originally signed Chikashige as his first maker’s name. However, he changed it to Yasushige after receiving 康 (Yasu) letter from Hojo Ujiyasu, a famous feudal lord he served.
After the Toyotomi clan destroyed the Hojo clan in the Azuchi Momoyama period, Shitahara started to serve the Tokugawa clan as Okakae Kaji, swordsmiths exclusively working for a specific feudal family.

 Most of the Shitahara swordsmith’s real sir name was Yamamoto. They especially flourished during the late Muromachi period-early Edo period. They kept forging for the Tokugawa clan until the end of the Edo period. Among the Bushu Shitahara group, Yasushige was one of the most famous makers.

 One of the most distinctive characteristics of the blades forged by Shitahara Kaji is Jorinmoku (如輪杢), which looks like a whirlpool on Hada (the steel surface of the Japanese sword).


  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 small Ishike (small black dots you can see in photos). Also, there is a Kitae Kizu on the Mune. If you like to see 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.


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.

 This Fuchi Kashira is decorated with the Ume (梅, Japanese apricot blossom) and Yukiwa (雪輪, snow ring) patterns. Gold and silver are effectively applied, and these colorings make this work’s ornamental look. Japanese apricot blossoms begin to bloom in winter when snow still covers its tree. People thought this flower told the arrival of spring. Same as cherry blossoms, it has been appreciated for a long time in Japan. People enjoy its adorable petal shape, scent, and gracefully branched trees and compose many poems. As it comes out in the cold season, it symbolizes the power of perseverance and vitality. Samurai might have favored this flower’s ability to persevere even in harsh conditions.

 The Yukiwa pattern is also related to the coming spring. The shape of snowflakes is the motif of this pattern. It is considered that snow is a sign of a plentiful harvest. Especially if snow in the New Year, people thought that year would have a bumper crop. Looking in this way, we now understand this Fuchi Kashira’s design is composed of two motifs that make us feel the arrival of the season when the snow that has accumulated in winter melts and the flowers that have withstood the cold bloom.

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

 In contrast to the Fuchi Kashira, this Menuki’s design is related to autumn. You would find the Kinoko (茸, mushroom), Kuri (栗, chestnut), and Ho (穂, ear). It seems golden paint was initially applied to each motif. Among these motifs, chestnuts have long been treated as a particularly auspicious object. The Kachi-Guri (搗栗, dried chestnuts) is sometimes found as a motif for sword mountings because of its name. This is because its name, “Kachi-Guri,” has the same pronunciation as Kachi (勝ち, victory). It has been treated as a good-luck omen and appreciated by Samurai to hope the success in battles. According to a theory, the famous Samurai, Takeda Shingen (武田 信玄, 1521-1573) cherished this vegetable. He instructed farmers to grow chestnuts in preparation for famine.

 Even during times of famine when crops were scarce, only chestnuts grew splendidly and saved many people from above. In addition, chestnuts were highly valued as food for warfare because of their long shelf life. Chestnuts were very useful because they could be eaten deliciously in the middle of a long battle. It is said that Shingen always brought chestnuts with him during wars. He won many battles, and people who thought it was the power of chestnuts came to cherish them even more. Shingen also believed it was an auspicious item and has come to like chestnuts even more. Today, chestnuts are enjoyed as a familiar food for Japanese people. For example, there is a traditional dish for Osechi-Ryori (お節料理, Japanese new year’s food) that contains chestnuts. It is called Kuri-Kinton (栗きんとん) and is always selected as a lucky charm to strengthen the fortune and game luck in new year’s Osechi dishes.

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 work depicts a man who enjoys fishing and indulges in thought. According to the certificate, this man is Taikoubou (太公望), who was a politician in China. His anecdote about fishing is well-known. One day, when the monarch of Shu (周) did a fortune-telling before going out to hunt, he was told that the prey was not an animal but an assistant to the overlord. While out hunting, the king met an old man fishing and fell in love with his talent. Convinced that this older man was the person the country had been waiting for, the monarch appointed him as his assistant. The country prospered under the advice of this assistant. This older man is Taikoubou.

 Therefore, the word “Taikoubou” is sometimes used as a pronoun for fisher in Japan. He is also famous as a character in the popular novel Houshin-Engi (封神演義). His legacy was narratively developed in later times. This book is one of the famous full-length novels that was born in such a situation.


Saya Saya is the scabbard for the Japanese sword.  

Authentication PaperNBTHK TOKUBETSU Hozon Certificate for the blade (No. 1016689)& Hozon Tosogu for the Koshirae (No. 4020361)

  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.
