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

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

Omi Daijyo Fujiwara Tadahiro<\/strong><\/span><\/p>\n

\u00a0This blade was signed by Omi no Daijyo Fujiwara Tadahiro (\u8fd1\u6c5f\u5927\u63be\u85e4\u539f\u5fe0\u5e83), who is the first son of the first-gen Tadayoshi. It is said that Tadahiro was active in sword-forging during 1624-1688<\/strong> (Early Edo Period).<\/span><\/p>\n

\u00a0Tadayoshi (Father) is one of the most famous swordsmiths in the early Edo period and made Hizen province (today\u2019s Saga prefecture) a prominent sword-forging place back then. Tadahiro learned sword-forging techniques under his father\u2019s supervision until Tadayoshi died in 1632 (9th year of the Kan-Ei era).<\/span><\/p>\n

\u00a0Tadahiro took over the school his father ran when he was only 19 years old, and he started to make a sword in the same year. This fact indicates that he was excellent at making swords, and the apprentices of his father (Tadayoshi) supported him to run the school. Tadahiro received the title of Omi Daijyo in 1641 (the sixth year of the Genroku era). He kept forging swords for almost 60 years for the Nabeshima clan, strong feudal lords.<\/span><\/p>\n

\u00a0Tadahiro died at the age of 81 in 1693 and left a large number of excellent swords before his decease. He had many famous apprentices, such as the third-gen Mutsu Daijyo Tadayoshi, Harima Daijyo Tadakuni, and Kawachi Daijyo Masahiro.<\/span><\/p>\n

\u00a0Fujiwara Tadahiro and other swordsmiths in the Hizen province worked under the auspices of Nabeshima clan. The swordsmiths in Hizen province were able to produce beautiful Jigane-patterned blades, also known as Hizen To, using and mixing carbon steel made in Netherland.<\/span><\/p>\n

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

The first-gen Tadayoshi (His father)<\/span><\/strong><\/p>\n

\u00a0The first-gen Tadayoshi was born and raised in the Saga domain. In 1596, under the domain\u2019s order, he went to Kyoto to learn the sword-forging technique from Umetada Myojyu(\u57cb\u5fe0\u660e\u5bff), one of the greatest swordsmiths in the early Edo period. He improved his craftsmanship and returned to the Saga domain two years later (1598). The first head of the Nabeshima clan, Nabeshima Katsushige, appreciated the work of the first-gen Tadayoshi very much. Then, Katsushige appointed him as his Okakaekaji, a swordsmith who exclusively forged swords for a specific domain or clan. And Tadayoshi started to stay near Saga castle, which is the headquarter of the Nabeshima clan. And, he founded Hizen Tadayoshi school, which trained more than 100 swordsmiths during the Edo period.\u00a0 Tadahiro is one of them.<\/span><\/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

*Please keep in mind that there is a couple of tiny chip on the tip of the blade as well as a couple of Kitae Kizu. If you like to see the detailed condition, please feel free to contact us.<\/span><\/span><\/em><\/p>\n

 <\/p>\n

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

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

\"\"<\/p>\n

 <\/p>\n

Koshirae:\u00a0Koshirae 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

 <\/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

\u00a0We believe that the motif of this fuchi-kashira is the clove (\u4e01\u5b50, ch\u014dji). Like pepper and other spices, cloves were originally valued for their medicinal properties in ancient times. In Japan, however, cloves also came to be appreciated as an auspicious motif in traditional decorative arts.\u00a0<\/span><\/p>\n

\u00a0As a design element, the clove symbolizes protection and health, reflecting its historical use in herbal medicine and incense. It became a common motif in sword fittings and textiles, admired not only for its elegant shape but also for the positive meanings it conveyed.\u00a0<\/span><\/p>\n

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

\u00a0We believe the theme of this Menuki is Seashells (\u8c9d\u5c3d\u304f\u3057, Kai Dukushi).<\/span><\/p>\n

\u00a0This pattern is a combination of different types of seashells. It is often designed with a seaside scene or wave pattern. You would feel the refreshing atmosphere of summer. Bivalves, especially clam, its shells cannot be combined with any other clam\u2019s frame; therefore, its pattern represents happy marriage.<\/span><\/p>\n

\u00a0Seashell is called Kai (\u8c9d) in Japanese. Because of its pronunciation, the seashell has another meaning. There is a word Yarigai (\u3084\u308a\u304c\u3044, worthwhile). As a part of this word has the same accent as Kai (\u8c9d is read Gai in some cases), Japanese people found this meaning. Also, since seashells are hard and combine only with their pair, people thought it represented a robust defense. Due to these meanings that inspire warriors who go to the battlefields, Samurais might have loved this motif.<\/span>
\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 is shaped in a mokkou (\u6728\u74dc) form. The mokkou pattern is commonly seen in traditional Japanese design, and the name “mokkou” is believed to be derived from mokou (\u5e3d\u984d), a type of silk cloth used to decorate the edges of curtains and blinds.\u00a0<\/span>Additionally, the mokkou pattern is one of the five major family crests (\u5bb6\u7d0b, kamon) widely used by many families in Japan. This design is considered a symbol of wishing for the prosperity of descendants and is often regarded as a good omen for the future.<\/span><\/p>\n

Authentication Paper<\/strong><\/span>\uff1aNBTHK TOKUBETSU Hozon Certificate for the blade (No. 1018846)<\/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 Aug 25th in the 4th year of Reiwa (2022). 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

Registration Number : Tokyo 61746<\/span><\/span><\/strong><\/span><\/p>\n

\u00a0The Board of Education in Tokyo 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
