Antique Japanese Sword Katana Signed by Masatada with NTHK Kanteisho Certificate<\/span><\/span><\/strong><\/p>\n

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

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

\u00a0This blade was signed by Ushu Akita Jyu Masatada (\u7fbd\u5dde\u79cb\u7530\u4f4f\u6b63\u5fe0) during the Genji era (1864-1865: The end of the Edo period). He was also known as Akimoto Yonekichi (\u79cb\u5143\u7c73\u5409) while his birthname was Miura Jyogrou Yoshinaga (\u4e09\u6d66\u5b9a\u4e94\u90ce\u5409\u9577). He was born as the second son of Miura Choheibei. Masatada was active in the late Edo period-early Meiji era (Late 19th century) and was a Samurai of the Dewa Domain (Today’s Akita prefecture). He was an Okakae Kaji for \u4f50\u7af9\u5317\u5bb6 (Satake Hokke family), who was a strong feudal family in Dewa domain. Okakaekaji is a swordsmith who exclusively served a specific domain or feudal lord, which is an honorable position for any swordsmiths back in the day.\u00a0 It is said that he once belonged to Suishinshi Masahide scho<\/span>ol, one of the most famous swordsmiths\/school during the late Edo period. According to available records, he forged many swords especially during the \u014cu War (\u5965\u7fbd\u6226\u4e89).\u00a0<\/span><\/p>\n

\u00a0The \u014cu War was a conflict that took place in 1868 in the northern region of Japan (the T\u014dhoku area). It was fought between the newly formed Meiji government and domains that had supported the former shogunate. Domains such as Aizu and Sh\u014dnai joined forces to oppose the new government, but were eventually defeated. As a result, Japan came under the unified control of the Meiji government. This war marked a major turning point, as Japan shifted from its old political system to a new, modern state.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

\n
The Background<\/strong><\/div>\n
\n

\u00a0Japan enjoyed a relatively peaceful time from the early Edo period to the mid-Edo period(the 1600s-1760s) because of the stable economy and the powerful government run by Tokugawa Shogun. Samurai didn\u2019t have many opportunities to utilize his Katana sword in public or on battlefields during this time. Thus, they carried their swords more as a symbol of their social status. The demand for weapons decreased accordingly compared to the previous Warring state period called Sengoku Jidai (1467-1600).<\/span><\/p>\n

\u00a0However, toward the end of the Edo period(1764-1876), the Japanese sword\u2019s role changed dramatically. With the poverty spreading in Japan, there were so many riots initiated by the civilians. Japanese sword started to play an essential role in maintaining public safety.<\/span><\/p>\n

\u00a0Pressure from foreign countries to open Japanese borders also forced Samurai to order strong-looking swords to survive this tumultuous time. We believe many swordsmiths, including Masada, made great efforts to forged high-quality, practical blades for their masters to prepare for battles.<\/span><\/p>\n

\u00a0There was a civil war between Tokugawa\u2019s military governm<\/span>ent and the new Meiji government at the end of the Edo period. That means the original owner of this Katana might have seen the moment when Samurai\u2019s life changed forever. Also, it is possible that this blade was carried by a Samurai who participated in this civil war based on the reputation of this swordsmith.<\/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

Koshirae\uff1aKoshirae 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

\u00a0The entire of this sword\u2019s Koshirae is designed with the common theme: Nozarashi-Zu (\u91ce\u6652\u56f3)<\/strong>. It refers to human bones that have been exposed to winds and rain in the open air and turned into skeletons, and it often refers to skulls in particular. This Nozarashi theme has been favored since a long time ago. We could imagine that people in those days had to live in harsher conditions. In addition, Samurai warriors were always on the verge of life and death on the battlefields. We would say this theme reflects on these aspects of society at that time.<\/span><\/p>\n

\u00a0It is not just the famous warlords who left their names in history who ran through the world of warfare. Each warrior whose name was not even recorded has their own history. However, after they lost their lives, they were simply left on battlefields and returned to nature. We would say that the Nozarashi-Zu is a subject that makes us feel the transience of nameless and precious lives scattered on battlefields and the transient after wars.<\/span><\/p>\n

\u00a0If we write it like this, you might feel melancholy. However, same as other designs, we hope each viewer will enjoy their own interpretation. By incorporating this motif into the sword mountings, Samurai warriors might have roused themselves toward the battlefield or included the desire to spend time with the souls of their former comrades in arms who had already lost their lives.<\/span><\/p>\n

\u00a0At first glance, you might feel that the Nozarashi-Zu has a frightening atmosphere, but the fact is that it was incorporated as part of the decoration. And it was treated as one of the elements that boosted the aspect of Japanese swords as a work of art. We interpret that it makes us feel a sense of the high sensitivity of the people of the time. In addition, the finish of each sword mounting is excellent, and the skillful technique of the artisans could be seen everywhere. We hope you appreciate the details of the Koshirae as well as the blade.<\/span><\/p>\n

*While this blade was made during the end of the Edo period, we assume its overall Koshirae was made later than this time period.\u00a0<\/span><\/em><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/article>\n

\u00a0The theme of this Tsuba is the same as other parts: Nozarashi. The sight of scattered bones lying alone in the wilderness, exposed to the wind, is a sad and lonely image. Yet, it also carries a powerful message: life is short, and because of that, it is beautiful and worth living to the fullest.<\/span>
