Antique Japanese Sword Tanto Attributed to Kanenori with NTHK Kanteisho Certificate 


 This blade is attributed to Noshu Seki Kanenori(濃州関 兼則) from the Eiroku era(1558-1570: late Muromachi period) according to NTHK that authenticated this blade. Kanenori is categorized as Sueseki, which refers to the sword makers from Mino province at the end of the Muromachi Period (Late 16th Century).

 The MINO swordsmith’s style, also known as MINO-DEN, basically has the TOGARI(Pointed shapes protruding from the Hamon )in a classic straight line and random temper line with some white Utsuri. MINO-DEN had its origin from YAMATO-DEN in the late KAMAKURA period(1280-1330). It flourished in the MUROMACHI period(1333-1573) and continued until the EDO period(1603-1868).

 MINO-DEN especially prospered during Sengoku Jidai(Warring State period) due to the high demand for weapons. And the location of Mino province beat others. Akechi Mitsuhide controlled Mino province, and Nobunaga Oda ruled Owari province, and Tokugawa Ieyasu was the lord of Suruga (Neighboring areas). There was high demand from those powerful feudal lords and their retainers. Furthermore, so many wars occurred between the Kanto region and the Kyoto area, and Mino is located in the middle, making feudal lords feel convenient to order swords from MINO-DEN. The blades forged in MINO provinces also had the reputation of its practical design and sharpness. Many feudal lords demanded swords forged in the Mino province. It would be nice to own the blade made during this warring state period.

* Please keep in mind that there are a couple of black rust and Kitae Kizu on this blade. If you like to know the detailed condition, please feel free to contact us. We will take photos and video and send them to you.

【 Blade】
Cutting Edge Length(Nagasa) 27.7 cm ( 10.9 inches)
Curvature(Sori)0.6 cm ( 0.23 inches)

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).

 The scabbard and handle are painted with the same color lacquer. It has a bright red color, and the Fuchi Kashira part is colored with black lacquer. When the blade part is stored in the scabbard, it even looks like an ornamental object, not a Japanese sword.

 You see that golden plants are designed with elegant gold paintings. This plant is probably the Hyoutan (瓢箪, gourd) from the shape of the fruit part. Since ancient times, Japanese people have appreciated this plant design as an auspicious motif. As mentioned above, the first letter of its Japanese name is pronounced as “Hyou.” Therefore, three gourds were associated with the San-Byoushi (三拍子, triple time). And people compared six gourds to the Mubyou Sokusai (無病息災, be in perfect health). It is because the word “病 (Byou)” has the same pronunciation as “瓢 (it also can be read Byou).” Also, the gourd pattern represents success in business and the prosperity of descendants as this plant produces lots of fruits. These meanings tell you how Japanese people love this design based on its acting superstitiously for good luck.

 Now let’s touch on an example of the relationship between the gourd motif and the Samurai culture. Toyotomi Hideyoshi (豊臣 秀吉, 1537-1598) is one of the most famous Samurais during the Warring States period (1467-1615). According to a theory, his Umajirushi (馬印, massive flag raised near the general Samurai on the battlefield) was the Senari-Byoutan (千成瓢箪). He was given the gourd motif for his Umajirushi from Oda Nobunaga (織田 信長, 1534-1582). It is said he added gourds every time he won the battles. This Koshirae’s maker might have decided to incorporate the gourd pattern into this Koshirae because of his (or its customer’s) desire to pay tribute to Hideyoshi’s career advancement. We hope you will love this unique Koshirae.

Authentication PaperNTHK-NPO Kanteisho Certificate for the blade
