Antique Japanese Sword Wakizashi Mumei SUKESADA with NBTHK Certificate

Genbe Sukesada(源兵衛祐定) was one of the most well-known swordsmiths in Bizen province.(Today’s Okayama prefecture.)He forged sword during 1532-1573 A.D. Based on the hamon(wavy pattern on the blade),the shape and the color of the carbon steel, the sword appraiser, NBTHK believed this sword was made by him.

Those who forged swords in the Bizen province(Okayama prefecture) at the end of the Muromachi Period(1492-1569 A.D) are called Matsu Bizen(Matsu mean the end). Sukesada school was one of the most famous schools and it flourished for generations among Osafune schools(The head branch). There were various styles forged by the generations of Sukesada during this period. There were about 60 swordsmiths who used Sukesada as his maker’s name in the Samura history. Bizen is the birthplace of Bizen Den,one of the most famous Japanese sword tradtion along with Yamashiro Den, Soshu Den, Mino Den and Yamato Den.

The swordsmiths in Bizen produced many swords during the Muromachi period as it was in the middle of the Sengoku period(Warring state period), and the demand for swords increased among strong feudal lords. The length of this blade is efficient and must have been easy for its owner to handle back then.  It would be nice to have a piece that was forged in the warring state period, when there was so much rivalry between warlords.

【Other Detail】

Fuchi-KashiraA pair of matching sword fittings that cover the upper and bottom parts of its sword hilt

 Autumn flowers decorate Fuchi Kashira. For example, chrysanthemum, Japanese bellflower, and bush clover are designed. Also, a butterfly resting its wings at the leaf is seen. As a deer is engraved for Kozuka, it might be unified as a design with autumn elements. 

Tsuka& MenukiTsuka is the handle of the Japanese sword and Menuki is its decoration(dragon and tiger)

 A lion and a dragon are designed as Menuki. People consider the lion the power of the sun; therefore, lion pattern has been believed that it would exorcise evil spirits and protect people.

 Initially, the dragon is an imaginary beast that is found in ancient Chinese traditions or myths. And it is a symbol of auspicious signs. Its body is likened nine animals: antlers are deer, the head is a camel, eyes are demons, the neck is a snake, belly is Mizuchi (a mythical animal in Japan which looks like a snake and have a horn and four legs), scales are fish, claws are falcons, palms are tigers, and ears are cows. It was thought that the dragon would reign at the top of all animals because of its odd-looking appearance. People appreciate this creature design as the all-purpose auspicious pattern.

Scabbard(Saya)Saya is the scabbard for the Japanese sword

KozukaKozuka is the short equipment used a comb or a short knife to cut something small 

 A deer is designed for Kozuka. In Japan, deer was once an essential food, and people used its leather for clothing, and its antler was processed for fishhooks or ornaments. However, the situation changed after rice cultivation became a popular life-style. People apotheosized deer and regard it as god’s messenger. Deer was incorporated into the theme of Japanese poetry in the Nara period (648-781), and people appreciated it as the symbol of love with a scene of the autumn landscape. It is said this animal pattern represents the prolongation of life and longevity.
