Antique Japanese Sword Katana Signed by the third-gen Yasutsugu with Tokubetsu Hozon Certificate 


This blade was forged by the third-gen Edo Yasutsugu(江戸三代康継), according to the NBTHK’s appraisal. The signature also says that it was made of foreign carbon steel(Nanban Tetsu:南蛮鉄). He was active in sword-forging during the Kanbun-Enpo era(Early Edo period: 1661-1680). He was the first son of the second-gen Yasutsugu, who made swords until 1645 and died in 1646.

It is said that the first-gen Yasutsugu was born in Shimosaka town in Shiga prefecture at the end of the Muromachi period(Late 16 century ). He built his career there until the beginning of the Keicho era(1596). However, he moved to Echizen province due to the relocation of the lord he served. He eventually was noticed and supported by Matsudaira Hideyasu, the third son of Tokugawa Ieyasu, who was the founder of the Edo government. Hideysu who was the feudal lord of Echizen province during the early Edo period.
With the support of Hideyasu, the first-gen Yasutsugu was able to establish the Echizen Shimosaka school. And his school’s fame became nationwide.
By Hideyasu’s recommendation, the first-gen Yasutsugu became Okakaekaji for the Tokugawa shogun family, meaning that he exclusively forged swords for the Shogun family. Yasutsu was acknowledged by the first and second Tokugawa Shoguns, Tokugawa Ieyasu, and Tokugawa Hidetada.
The first-gen Yasutsugu received 康(YASU) from Tokugawa Ieyasu and changed his maker’s name. He was also allowed to inscribe the holly oak symbol(family crest of Tokugawa) on the tang.

The first-gen died in 1621, and the first son of him took over the school and became the second-gen Yasutsugu. As we explained earlier, the second-gen was deceased in 1646.The third-gen Edo Yastsugu was the first son of the second-gen Yasutsugu. His real name is Umanosuke(右馬助).
When the second-gen was deceased in the third year of Seiho(1646), Umanosuke was just 17 years old. Because of his young age, there was a dispute within the Echizen Yasutsugu school over who took over the school. The students of the second-gen Yasutsugu and Shogun’s arms office supported Umanosuke to be the third-gen Yasutsugu. However, the third son of the first-gen Yasutsugu insisted that he should be the one to take over his father’s school and property. The third son of Yasutsugu was Shirouemon(四郎右衛門) and younger brother of the second-gen Yasutsugu.

This dispute was eventually solved in such an interesting manner. Yasutusu school decided to have two third-gen Yasutsugu. While Umanosuke was officially appointed as the heir of Yasutsu school and became the third-gen Yasutsugu in Edo city, Shirouemon founded the Echizen Yasutsugu school. From this point, there were two branches of Yasutsugu school; Edo and Echizen.
Back then, Yasutsugu swordsmiths were requested to forge swords in Echizen and Edo back and forth every year, but this tradition ended after this dispute was settled.

Edo Yasutsugu school lasted for the 12th generation from the third-gen Edo Yasutsugu, and Echizen Yasutsugu lasted for the 9th generation. The work of the third-gen Yasutsugu resembles that of the first two generations, and his craftsmanship is said to be excellent among Japanese sword experts.

This blade cutting edge size is 75.1 cm(29.56 inches) and we assume it must have been owned by a highly skilled Samurai who could handle this long edge well. Since this blade was forged by a prestigious swordsmith, we believe it was owned by a high ranked Samuirai official in Edo.

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.

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 dragon is the motif of this Fuchi Kashira. They are engraved semi-three-dimensionally, and their eyes are colored with gold. The background of this Fuchi Kashira is decorated with small dots. This type of surface is called the Nanako-Ji (魚子地). By hitting with the Nanako-Ji Tagane (魚子地鏨, chisel used for this technique), delicate fish egg-shaped protrusions are made on the entire surface of the Tsuba. It shows us the maker’s expert skill.

Initially, the dragon is an imaginary creature found in ancient traditions or myths. Furthermore, this beast has been regarded as a symbol of auspicious signs. Its body is likened to nine animals: antlers are deer, the head is a camel, eyes are demons, the neck is a snake, belly is Mizuchi (蛟, mythical animal in Japan which looks like a snake and have a horn and four legs), scales are fish, claws are falcons, palms are tigers, and ears are cows. It was thought that the dragon would reign at the top of all animals because of its odd-looking appearance. Still today, the dragon pattern maintains its meaning as the all-purpose auspicious pattern.

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

Due to wear caused by aging, it is challenging to judge the entire original design of this Menuki. Seeing the shape from the gaps of Tsukamaki Ito (thread coiled on the handle), it seems that Samurais’ figure in small boats is depicted. The golden parts might be their armors. Since the other sword mountings’ motif are dragons (a god beast regarded as a water god), this Menuki’s design might have been chosen, wishing them success in the battle on the water and the safe return.
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. 
Same as the Fuchi Kashira, this Tsuba is also decorated with the dragon motif. The dragon twists its slender snake-like body in a circle. And the clouds cling around the dragon. According to a theory, dragons and gods dwell in clouds.

In Japan, there is a belief that worships a dragon as a water god. This faith is called Ryujin Shinkou (竜神信仰). Since rice cultivation flourished in this country, water is always an essential resource. People believed that the dragon would control water, and clouds bring blessed rain. It might be the reason why the combination of dragon and cloud design is often seen.

Saya Saya is the scabbard for the Japanese sword.
