Antique Japanese Sword Wakizashi Signed by Umetada Myoju (#Niigata 349)



 This blade has the inscription of Yamashiro Koku Nishijin Jyunin Umetada Myoju (山城国西陣住人埋忠寿). We believe the signature is Gimei (偽名: not genuine signature) Please keep in mind that that there is NO GUARANTEE of its signature’s authenticity because it doesn’t come with any certificates. The registration paper was issued by the board of the education in Niigata for this Wakizashi. That means that Bunkacho (The Agency for Cultural Affairs) acknowledges this as a work of art. The sword needs to be traditionally hand-forged and made of Tamahagane carbon steel to be registered in the system. You can see beautiful Hamon (tempering line) on the blade as well as gorgeous Koshirae (sword mounting).

 WAKIZASHI refers to a 30-60 cm long blade (11.8-28.6 inches) and was worn on the waist along with UCHI-GATANA(Katana). Samurai carried WAKIZASHI as a backup sword next to Katana. Samurai needed to use Wakizashi when he fought in a small room or with proximity where Katana would be too long to unsheathe.  Also, when Samurai entered a castle, he had to leave his Katana to the castle guard. In contrast, Wakizashi was allowed to bring inside as self-protection.

 WAKIZASHI was also the sword for the famous Samurai custom called SEPPUKU(切腹; Stomach-Cut), the ritual act of Samurai to take responsibility for crime act or losing battles.

 The use of Wakizashi became more widespread among Samurais during the Edo period. (1603-1868 A.D. ) Because the Edo Government had launched the national law to force all Samurais to wear two Japanese swords (Katana and Wakizashi) to identify themselves as the regime’s military officers.


What is the material of Japanese sword? 

 Japanese blacksmithing has over a millennium of history.  It dates back to the 1st century A.D. when ancient blacksmiths studied template method from the continent. Copper pottery and rice farming techniques were also introduced to Japan at the same time.

Since then, Japanese blacksmiths had spent centuries to invent the traditional metal forging technique called TATARA(鑪).  TATARA is a clay melting pot where you put iron sand and charcoal together to bond these chemicals with intensive heat. By using this technique, they started to make Japanese swords out of Tatara carbon-steel. This type of carbon-steel was later called TAMA-HAGANE (玉鋼; Ball-Steel).  

Horimono (Engraving)

 The Horimono (彫物, blade sculpture) is one of the elements of this blade’s beauty. Two different Horimos are engraved on each side. The one is the Suken (素剣) pattern. It is a simplified design of the Sanko-Duka-Ken (三鈷柄剣), which is a sword that the Fudo Myo-O (不動明王acalanātha, one of the objects of worship in Buddhism) brings. It is an esoteric Buddhist tool used for esoteric prayer, meditation, purification, and amulets. It is believed that this sword would exorcize evil spirits. The other side shows dragon.

 Initially, the dragon is an imaginary creature found in ancient Chinese traditions or myths. Furthermore, it is regarded as a symbolic beast of auspicious signs. Its body is likened to nine animals: antlers are deer, the head is a camel, eyes are demons, the neck is a snake, belly is Mizuchi (蛟, 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. Also, in Japan, there is a belief that worships dragon as a water god and is called Ryujin Shinkou (竜神信仰). Since rice cultivation flourished in this country, water is always an essential resource. Therefore, the dragon motif has been familiar to Japanese people since a long time ago. 

*Please keep in mind that there is no certificate for this blade.

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).
