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

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

Summary<\/strong><\/p>\n

\u00a0This blade was forged by Kanetsugu (\u5305\u6b21), who belonged to the Monju school (\u6587\u73e0\u4e00\u6d3e), a branch of the prestigious Yamato Tegai school (\u5927\u548c\u624b\u63bb\u6d3e). Kanetsugu\u2019s place of origin was Yamato province (today\u2019s Nara prefecture), and he was also known as Monju Rokubee. He is said to have been a disciple of Mutsu-no-kami Kaneyasu (\u9678\u5965\u5b88\u5305\u4fdd), also known as Hidari Mutsu. Kanetsu’s signatures are known in different forms, including \u201cKanetsugu\u201d and \u201cSesshu-j\u016b Monju Kanetsugu\u201d (\u6442\u5dde\u4f4f\u6587\u73e0\u5305\u6b21). <\/span>Kanetsugu was active around the Kanbun era of the Edo period (1661\u20131673), producing works that reflect the dignified style of the Yamato tradition while also showing the influence of his teacher and lineage. One of the most famous figures that belong to this Monju school is Nanki Shigekuni.\u00a0<\/span><\/p>\n

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

The foundation of Tagai school<\/strong><\/p>\n

\u00a0The first-gen Kanenaga is known as the founder of Tegai school. The school was prosperous during the late Kamakura-mid Muromachi period (1288-1460). It is said that Tegai school belonged to Todaiji temple, and it was located in front of the gate called Tengai Gate (\u8f3e\u78d1\u9580). The school name Tegai originally came from the sound of Tengai Gate.<\/span><\/p>\n

There were five prestigious schools, including Tegai school, during the Kamakura-Nanbokucho period in Yamato province. They are called Yamato Goha (\u5927\u548c\u4e94\u6d3e); Senjyuin (\u5343\u624b\u9662), Shikkake (\u5c3b\u61f8), Taima (\u5f53\u9ebb), Hosho (\u4fdd\u660c) and Tegai (\u624b\u63bb) school. They served politically powerful monks and temples in Nara, such as Todaiji temples. They were initially forging swords for military monks who became powerful due to the government\u2019s policy back then.<\/p>\n

Monks needed many weapons as there were many political rivalries between influential temples. They required strong weapons like swords to protect themselves. During this time, Tegai school or other Yamato sword schools met the requests from monks. They also forged blades for Samurai during their heyday. It is often the case that those who belonged to Yamato Goha didn\u2019t inscribe their signatures.<\/p>\n

 <\/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). This authentication paper was only given to authentic Japanese swords, especially well preserved and high quality with artistic value.<\/span><\/p>\n

 <\/p>\n

*Please keep in mind that there are some noticeable black rust on the tip of the blade.\u00a0 If you don’t mind waiting additional time, we can have it polished so that the rust part will become much less noticeable. We won’t charge additional cost. If you like to know the detailed condition, please feel free to contact us.<\/em><\/span><\/p>\n

\"\"<\/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

 <\/p>\n

Koshirae<\/strong>\uff1a<\/span>Koshirae 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

\u00a0<\/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 theme of this Fuchi Kashira’s design is the Ebi (\u6d77\u8001, shrimp) inlaid with golden metal (probably brass).<\/span><\/p>\n

\u00a0According to a theory, Japanese people already ate shrimp in the Heian period (794-1185). However, it was expensive for ordinary citizens, so that only the nobility and high-class people could enjoy it. Today, shrimp is an indispensable ingredient for Japanese New Year\u2019s cuisine. People started using shrimp as a good-omen pattern and appreciated designing it for their family crests in the Muromachi period (1336-1573). In Samurai\u2019s society, as shrimp is covered with a hard shell, it was thought that shrimp represents the figure of a brave Samurai who wears the armor. Shrimp has been likened to an older adult because of its long feelers. Also, shrimps actively jump even though they are bowed. That is the reason why the shrimp pattern is treated as a symbol of perpetual youth and longevity.<\/span><\/p>\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

The theme of this Menuk appears to be\u00a0 a chrysanthemumu(\u83ca, Kiku).\u00a0\u00a0Chrysanthemum is one of the flowers that symbolize fall, and people have appreciated it very much since ancient times. A long time ago, the chrysanthemum was used as a medicine to obtain a long life in China, and it was brought to Japan with this thought in the Nara period (648-781).\u00a0<\/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

\u00a0This Tsuba might be categorized as the Nanban Tsuba (\u5357\u86ee\u9354), which means it was imported from overseas or created by imitating foreign-style Tsuba. The term \u201cNanban\u201d refers to a foreign country that includes Portugal, Spain, and, in a broader sense, China. Nanban Tsuba began to be imported from overseas in large numbers around the end of the Muromachi period (the mid 16th century), and it is said that foreign Tsuba makers were also making Tsubas in Nagasaki in the Edo period.<\/span><\/p>\n

\"\"<\/p>\n

Saya<\/strong><\/span>\uff1aSaya is the scabbard for the Japanese sword.\u00a0\u00a0<\/strong><\/span><\/p>\n

\u00a0The surface of this Saya is decorated with the Ishime-Ji (\u77f3\u76ee\u5730). Its base was hit by Tagane (\u93e8, chisel for metalworking), and it makes a rough surface that seems stone.\u00a0<\/span><\/p>\n

Authentication Paper<\/strong><\/span>\uff1aNBTHK TOKUBETSU Hozon Certificate for the blade (No. 1024354)<\/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 February 21st in the 7th year of Reiwa (2025). 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<\/span><\/a><\/span> for your record if you request.<\/span><\/p>\n

\"\"<\/p>\n

Registration Number : Kyoto 52523<\/span><\/span><\/strong><\/p>\n

\u00a0The Board of Education in Kyoto issued a registration paper for this sword. It is called Jyu Hou Token Rui Tourokusho (\u9283\u7832\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
