Antique Japanese Sword Katana Signed by Yasutsuna with <\/span>Tokubetsu Hozon<\/span> <\/span>Certificate<\/span>\u00a0<\/span><\/strong><\/p>\n

\u3010Description\u3011<\/strong><\/span><\/p>\n

\u00a0This blade was signed by Kii Koku Yasutsuna (\u7d00\u4f0a\u56fd\u5eb7\u7db1), who belonged to Kishu Ishido school. He was active in sword-forging during the Kanbun era (early Edo period: 1661-1673<\/strong>). He was an apprentice of the first-gen Bitchu no Kami Tachibana Yasuhiro.<\/span>
\n\u00a0Kii koku is the name of the province located in Wakayama prefecture today. He is known as one of the most famous swordsmiths from the Kishu Ishido school during the early Edo period. There was also a record of Yasutsuna forging in Osaka.<\/span><\/p>\n

\u00a0Ishido school was initially founded by Sukenaga, an offspring of Ichimonji Sukemune, who had created Fukuoka Ichimonji school in Bizen province (Today’s Okayama prefecture).<\/span>
\n\u00a0During 1492-1501 (Mid Muromachi period), Sukenaga and his school moved from Bizen province to Omi province after being summoned by Gamou family, a powerful feudal line in that region. Sukenaga started to live in front of Ishido temple, and he changed his surname to Ishido.<\/span><\/p>\n

\u00a0As of the early Edo period, many Ishido swordsmiths in Omi province moved to other parts of Japan. There are four major branches: Edo, Osaka, Kishu (Wakayama prefecture), and Chikuzen (Fukuoka prefecture). Omi Ishido school was the origin of whole other Ishido branches that flourished during the Edo period.<\/span>
\n\u00a0Following this trend, Bitchu no Kami Tachibana Yasuhiro, the master of Yasutsuna, moved to Kishu province from Omi province. It is said that Yasuhiro was the founder of Kishu Ishido school. Yasutsuna and his master forged swords near Wakayama castle in Kishu province. Judging from the fact that Yasutsuna worked for this skilled master, his craftsmanship must also have been excellent.<\/span><\/p>\n

\u00a0It is appraised as a Tokubetsu Hozon Token <\/strong>(\u7279\u5225\u4fdd\u5b58\u5200\u5263) issued by NBTHK (Nihon Bijutsu Touken Hozon Kyokai:\u65e5\u672c\u7f8e\u8853\u5200\u5263\u4fdd\u5b58\u5354\u4f1a).

 <\/p>\n

Nakago<\/strong><\/span>\uff1aNakago is the tang of the Japanese sword. <\/strong><\/span><\/p>\n

\u00a0Japanese 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.<\/span><\/p>\n

 <\/p>\n

Koshirae\uff1aKoshirae is the mounting of the Japanese sword. There are several parts that consist of Koshirae such as Saya (Scabbard), Tsuka (Handle), Tsuba (Handguard).<\/span><\/strong><\/span><\/p>\n

 <\/p>\n

Fuchi-Kashira<\/strong><\/span>\uff1aA pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.<\/span><\/strong><\/p>\n

\u00a0The motif of this Fuchi Kashira is the peony (\u7261\u4e39: Botan). <\/span><\/p>\n

\u00a0The peony represents happiness, wealth, nobleness, and gorgeousness. This flower pattern has been treated as a kind of good-omen motif; people regarded it as a rich harvest sign. Peony is called \u201cBotan\u201d in Japanese. When we write this flower\u2019s name in Japanese, its second letter means mountain hermit medicine that would give us eternal youth. Based on the meaning of this letter, the peony pattern symbolizes eternal youth and longevity.<\/span><\/p>\n

\u00a0<\/span>
\n\"\"<\/p>\n

Tsuka and Menuki<\/strong><\/span>\uff1aTsuka is the handle of the Japanese sword and Menuki is its decoration.<\/b><\/span><\/p>\n

\u00a0The motif of this Menuki is the horse (\u99ac: Uma). You would find two horses wearing the Kura (\u978d: horse saddles), which suggests they are thought to be used for going to the battlefields. These horses also have golden eyes, and one has a golden mane.\u00a0<\/span><\/p>\n

\u00a0Horses have been around human life for a long time, not only as our food but also for transportation or carriage of luggage. In Japan, horses were thought of as vehicles for gods to be dedicated to shrines in ancient times. It is said it is the origin of Ema (\u7d75\u99ac, picture tablet used as an offering at a shrine) today. Horses had been used as a tool for rituals and festivals. After the age that Samurai appeared, wearing large armor or performing archery riding a hose became martial arts. Equestrian tactics became the pillar of military action and security activities. According to a theory, that is why the Japanese sword began to have a curve to make it suitable for slashing (the Japanese sword was straight in the beginning).<\/span><\/p>\n

\"\"\u00a0 \u00a0 \"\"<\/p>\n

Tsuba and Habaki<\/strong><\/span>\uff1aTsuba 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.\u00a0<\/span><\/strong><\/p>\n

\u00a0The theme of the Tsuba is the asarum caulescens (\u8475: Aoi) and the the arabesque (\u5510\u8349: Karakusa). <\/span><\/p>\n

\u00a0The asarum caulescens is a plant with each stem branch and characteristic heart-shaped leaves. As its leaves have a habit of always facing the sun, and the word \u201cAoi\u201d is taken as \u201cAogu (\u4ef0\u3050, looking up)\u201d for the sun, people thought the Aoi pattern would bring good fortune.<\/span><\/p>\n

\u00a0The Karakusa (\u5510\u8349) pattern is a pattern in which stems and leaves of vines are twined and make curves. Since ivy has a strong vitality and grows up without interruption, people regarded this design as a symbol of prosperity and longevity. Vine is called Tsuru (\u8513) in Japanese, and it has another pronunciation; \u201cMan.\u201d There is a word \u4e07 (it is also read Man), which means ten thousand. In the Karakusa pattern, leaves and vines are connected like Obi (\u5e2f, belt). The word \u201c\u5e2f\u201d can also be read \u201cTai.\u201d Due to its pronunciation, the term \u201c\u4ee3 (Tai)\u201d is associated. From this word-association game, an idiom \u4e07\u4ee3 is associated, and it means a thousand generations. In other words, we could imagine that people used this design wishing prosperity and longevity for their clans for a long time.<\/span>

Authentication Paper<\/strong><\/span>\uff1aNBTHK TOKUBETSU Hozon Certificate for the blade (No. 1022183)<\/strong><\/span><\/p>\n

\u00a0\u00a0NBTHK<\/a><\/span><\/span>, 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 Feb 21st in the 6th year of Reiwa (2024). They appraised it as Tokubetsu Hozon Touken, the blade especially worth preserving for Japanese society. The purchaser will receive this original certificate as well.

Registration Number : <\/span>Okayama 79435<\/span><\/span><\/strong><\/p>\n

\u00a0The Board of Education in Okayama prefecture issued a registration paper for this sword . It is called Jyu Token Rui Torokusho (\u9283\u5200\u5263\u985e\u767b\u9332\u8a3c). Bunkacho (The Agency for Cultural Affairs) acknowledges a Japanese sword with this paper as a work of art.
\nThe sword needs to be traditionally hand-forged and made of Tamahagane carbon steel to be registered in the system. With this paper, its owner in Japan can legally own an authentic Japanese sword. Based on this registration number, we will apply for its export permit.
\nThis paper will need to be returned to the board of education when the sword is being shipped abroad, but you can receive a copy of it. An English translation of this registration paper is available on request.<\/span><\/p>\n
