Antique Japanese Sword Wakizashi Signed by Yasutsugu Nyudo with NBTHK Tokubestsu Hozon Certificate
【Description】
Summary
This blade was signed by Yasutsugu Nyudo (康継入道), also known as the second-gen Yasutsugu, who was active during the Kanei era (1624-1644: Early Edo period). The signature also says this blade was made of western carbon steel called Nanban Tetsu (南蛮鉄) with general Tamahagane. Foreign carbon steel was costly back then, and either the swordsmith or the person who ordered it wanted to be proud of the social status by inscribing this fact. The maker’s name, Yasutsugu, lasted twelve generations, and the first and second generations are the most acknowledged swordsmiths among them. Based on the signature of this blade, it was made in Edo (Today’s Tokyo).
The second-gen Yasutsugu initially signed Yasutsugu (康次). As you can see, the Kanji letter of Tsugu (次) is different from his later name Tsugu (継). His birthname was Shimosaka Ichinojo. We would like to explain who the first-gen Yasutsugu was before describing the second-gen.
It is said that his father, the first-gen Yasutsugu, was the founder of the Echizen Shimoasaka school. 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 founded the Edo government. Hideysu 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 an Okakaekaji for the Tokugawa shogun family, meaning that he exclusively forged swords for the Shogun family. The first and second Tokugawa Shoguns, Tokugawa Ieyasu, and Tokugawa Hidetada acknowledged the first-gen Yasutsu’s craftsmanship, too. The first-gen Yasutsugu received 康(YASU) from Tokugawa Ieyasu in the 11th year of the Keicho era (1606) and changed his maker’s name. He was also allowed to inscribe the holly oak symbol(family crest of Tokugawa) on the tang. The school flourished during the Edo period and trained many skilled apprentices, such as the second-gen Yasutsugu.
After the first-gen was deceased in the 7th year of the Genna era (1621), the second-gen took over his father’s position. The second generation was ordered by Tokugawa Hidetada, the second Shogun, to live in Edo city, forging blades. Tokugawa Hidetada had faith in the second-gen Yasutsugu. It is said that the second-gen Yasutsugu worked very closely with the Shogun and was accompanied at the Shogun’s important events, such as hunting with a falcon. The second Yasutsugu lived in both Echizen and Edo, going back and forth every other year. However, in 1623, he settled in Edo City under the government’s order.
Later in his career, he became a Buddhist priest and changed his maker’s name to Yasuetsu (康悦) from the 13th-14th year of the Kan-Ei era (1636-1637). Nyudo, the letter inscribed on this Wakizashi also means a monk. This means that it must have been made in his late career. He died in the third year of the Seiho era (1646). After he died, there was a historically interesting dispute over who would take over the school. From the third generation, there were two Yasutsugu schools. One was located in Echizen, and the other was in Edo. You can check more details from here.
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.
【Blade】
Cutting Edge Length(Nagasa)：45.0 cm (17.7 inches)
Curvature(Sori)：0.84 cm (0.33 inches)
Hamon：
The crystalline structure which forms along the cutting edge of a blade as a result of the hardening process
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.
A traditional Japanese house and Ume are depicted on this Fuchi Kashira. The Ume (梅, Japanese apricot blossom) is depicted on this work. Japanese apricot blossoms begin to bloom in winter when snow still covers their trees; people thought this flower tells the arrival of spring. The same as cherry blossom, it has been appreciated for a long time in Japan. People enjoy its adorable petal shape and scent and gracefully branched tree, and they have composed many poems about it. As it comes out in the cold season, it symbolizes the power of perseverance and vitality.
Tsuka and Menuki：Tsuka is the handle of the Japanese sword and Menuki is its decoration.
Chrysanthemum is the theme of this Menuki. 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. “Kiku no Gomon (菊の御紋)” is a kind of chrysanthemum pattern, and it has been used as the crest of the Emperor and the royal family in Japan so that it is well-known as a noble pattern.
From the Kamakura (1185-1333) period to the Warring States period (1467-1615), the chrysanthemum crest was given as a reward from the Emperor back then to the warlords who made significant contributions. For example, Ashikaga Takauji (1305-1358), who became the first Shogun of the Muromachi Shogunate, cooperated with Emperor Go-Daigo (後醍醐天皇, 1288-1339) to dissolve the Kamakura Shogunate. And Takauji was given a chrysanthemum crest.
In addition, Toyotomi Hideyoshi (1537-1598) was also given a chrysanthemum crest by Emperor Goyouzei. A theory says Hideyoshi was delighted and used this motif for furniture. At that time, the Emperor was regarded as God. Therefore, it was an irreplaceable honor for Samurais to receive the family crest from the Emperor. This is how the chrysanthemum pattern has a deep connection with Samurai culture.
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.
Kozuka：Kozuka is a small knife stored in Kozuka Hitsu(groove of the sheath of the Japanese sword).
We estimate its design is either the Fujin (風神) or the Raijin (雷神). 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.
Saya： Saya is the scabbard for the Japanese sword.
This Saya is coated on stingray skin, which adds gorgeous appearance.
Authentication Paper：NBTHK Tokubetsu Hozon Certificate for the blade (No. 1021762)
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.

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.
