Antique Japanese Sword Katana Signed by Awataguchi Omi no Kami Tadatsuna with Tokubetsu Hozon Certificate 【Description】 This blade was signed by Awataguchi Omi no Kami Tadatsuna (粟田口近江守忠綱). The maker’s name Tadatsuna lasted two generations, and we believe it was forged by the first gen, judging from the characteristics of the blade. He was one of the top-tier swordsmiths during the early Edo period. He was especially active in sword-forging during the Kanei-Manji era (1624-1661). Also, the signature also says that this blade was made from western carbon steel called Nanban Tetsu (南蛮鉄: mixed with traditional Tamahagane). Foreign carbon steel was very expensive back then and either swordsmith or the person who ordered it wanted to be proud of the social status by inscribing this fact. Tadatsuna was born in the 14th year of the Keicho era (1609) as the son of Asai family in Himeji city, Harima province (Today’s Hyogo prefecture). It is said that he called himself an offspring of Awataguchi Kunitsuna, one of the most famous swordsmiths in Yamashiro province (Today’s Kyoto) during the late Heian-early Kamakura period. This is why Tatasuna signed Awataguchi at the beginning of his signature. According to available records, the earliest work the first-gen Tadatsuna created is from the 6th year of the Kan-Ei era (1629). And he started to forge swords in Yamashiro province in the 14th year of the Kan-Ei era (1637). Eventually, he moved to Osaka in the first year of the Keian era (1648). The latest work signed by the first-gen Tadatsuna is in the 4th year of the Enpo era (1676), when he was 67 years old. His son, the second-gen Tadatsuna, is also known as Ikanshi Tadatsuna, and he is one of the most renowned swordsmiths in Osaka during the early Edo period. He mastered excellent sword-forging techniques from his father, the first-gen Tadatsuna. Osaka Shinto The blades forged by Tadatsuna are categorized as Osaka Shinto. Shinto is Japanese Sword terminology that refers to the swords forged during 1596-1781. The blades made in the Osaka area during this period are called Osaka Shinto. There are many famous swordsmiths in this Osaka Shinto era. After Hideyoshi Toyotomi built Osaka castle, Osaka city flourished as a castle town and became the business center. Many swordsmiths moved to Osaka to look for better opportunities. They not only forged swords for those Samurai who lived in Osaka but also for feudal lords nationwide. Ikanshi Tadatsuna(Awataguchi Omi no Kami Tadatsuna), Inoue Shinkai, and Tsuda Sukehiro are the most famous among many swordsmiths. One of the most notable characteristics of Osaka Shinto is its beauty in Jigane. Jigane is a visible steel surface pattern created by folding and hammering during the forging process), which made it possible by the location of Osaka. Osaka had close access to the Tamahagane(special carbon steel to make Japanese swords) production sites. The swordsmiths residing in Osaka were able to get high-quality carbon steel from these sites. Horimono (Engraving) *Please keep in mind that although Awataguchi Tadatsuna was also famous for his carvings, the carvings on this blade were done by a different artisan according its NBTHK certificate. This blade features exquisite engravings (Horimono, 彫り物) on both sides of the blade. On one side, an intricate carving of Fudō Myō-ō riding a dragon (倶利伽羅不動, Kurikara Fudō) is depicted. Fudō Myō-ō is a guardian deity in esoteric Buddhism, known as the “Immovable One.” He is revered for his role in repelling evil and guiding people toward the righteous path, making him especially venerated by samurai warriors. The dragon depicted in this engraving is known as Kurikara Ryū-ō (倶利伽羅龍王), a dragon deity considered an incarnation of Fudō Myō-ō himself. Kurikara Ryū-ō is believed to be a divine protector, enveloped in blazing flames that burn away all obstacles and evil. While dragons are traditionally seen as powerful mythical creatures, Kurikara Ryū-ō embodies the very po

Shinto Tadatsuna忠綱

1 重要文化財3 特別重要刀剣49 重要刀剣

一竿子忠綱は二代粟田口近江守忠綱、初代近江守忠綱の子で、元禄期を代表する大坂の刀工の一人である。説明書は、通称を万太夫といい、父を継いで二代目の近江守を受領し、粟田口国綱の後裔と称して銘に粟田口を冠し、元禄二年頃より一竿子と号し始めたと記す。当時の大坂を代表する工の一人で、その作はまさに「地刃の華麗と彫刻の装飾美を以て名高い」。初期の作風は父に近く、その記録の中心は、自らの彫の場を兼ねた身幅広い在銘年紀の刀にある。 本工の特色はまず刃文に読まれる。よくつんだ小板目に、元を直ぐの焼出しに起こし、相関わる二様を焼く。古く受け継いだものは、焼頭のよく揃った足の長い丁子で、初代の得意とした作域そのものであり、長い丁子の足が入り、その足を砂流し・金筋が切って入る。説明書は本工を「父に優る名手で」と評し、その違いを的確に指す。初代の丁子が揃って堂々たるのに対し、二代は匂深く、匂口明るく、小沸のよくつくところで、これを出藍すなわち藍より出でて藍より青しと呼ぶ。 円熟の最も個性的な手は濤瀾乱れ、すなわち収集家のいう簾刃である。説明書はこれを津田助広の系に結びつけ、ある脇指において「得意の津田風の濤欄刃をやき」と記す。よくつんだ小板目に地沸が微塵に厚くつき地景細かに入る地に、浅いのたれを基調として互の目・丁子風を交え、これが大きく波打って濤瀾となり、なお長い丁子の足が入り、匂深く小沸厚くつき、砂流し・金筋頻りにかかり、匂口明るく冴える。帽子は浅くのたれ込んで小丸、掃きかける。穏やかな直刃も数口に残り、三つの面のうち最も静かで稀なもので、同じ明るい小板目の地に焼かれる。 その地鉄は三様すべての底に変わらず通う。鍛えはよくつみ細かによくつんだ小板目で、地沸が厚く、最上手には微塵につき、細かな地景が地を走り、地鉄は明るく冴える。素朴な地ではなく、よく出来た大坂の地であり、刃も彫もこの地の上に置かれる。剣書は本工の作域を、初代に倣う揃った丁子、濤瀾、そして稀な直刃とし、いずれも大坂の長い直ぐの焼出しより起こすとする。 地刃のいずれの特徴にもまして本工を分かつのは彫である。説明書はその刀身彫刻を一竿子彫として賞玩し、「出藍の誉高く」、また「殊に刀身彫刻は巧みで一竿子彫として賞玩されている」と記す。櫃中に真の倶利迦羅を浮彫にし、梅倶利迦羅、玉追龍、そして鯉の滝上りを彫った。鯉の滝上りは本工が初めて試みたものと思われ、説明書は「同作中でも本刀以外には未見である」とする。彼は大坂の彫物師藤田通意と関係が深く、「彫同作」と添銘して彫を自身の手と示した。これは初代には全く見られないところで、新刀彫刻に一種の型をつくったものである。 収集の観点では、一竿子忠綱は大坂新刀の主要な名跡で、その作はなお求め得るが、最上のものは商われるより蔵される。藤代の極めは上々作。国宝はなく、その記録は重要刀剣に数多く、特別重要刀剣に数口が及び、長銘の大太刀は重要文化財に達する。説明書はある特別重要刀剣の刀を、最も油ののった時代の代表作で地刃の出来に優れるとし、その一竿子彫を一段と見事とする。特別重要刀剣・重要刀剣の級にはおよそ五十二口が立ち、京都国立博物館に蔵される一口があり、浅井家に伝来した記録のある一口がある。在銘年紀で数も相応に残るため、忠綱は同格の大坂の名手のうちでは比較的世に出やすいが、自らの一竿子彫を帯びた年紀の刀は出れば見ものであり、鯉と倶利迦羅を本工自身が彫った最上のものは、大坂彫刻の極盛を語る証である。
