Antique Japanese Sword Katana signed by Kunishige with NBTHK Hozon Certificate 【Description】 This blade was signed by Bitchu Koku Mizuta Jyu Kunishige(備中国水田住国重). It is estimated that this swordsmith was active during the early Edo period( Mid-Late 17th century ). Kunishige belonged to Bitchu Koku Mizuta school, which had been founded by the descendants of Ko AOE Tametsugu(古青江為次) in the late Muromachi period(1530-). Tametsugu is one of the most famous swordsmiths in the late Heian period-early Kamakura period(Late 12C-Early 13C). One of his works is designated as a national treasure of Japan. AOE(青江) is the name of the school Tametsugu belonged to. It was located in Kurashiki city, Okayama prefecture today. AOE school was prosperous during the Kamakura-Nanbokucho era(-Late 12C-Late 14C), but it almost disappeared in the Muromachi period. However, because of the descendants of Tametsugu, the Ko AOE-style sword became popular again and revitalized the school by changing its name to Bitchu Koku Mizuta school. The Bitchu Koku Mizuta school flourished from 1530-1700(The end of the Sengoku period to the mid-Edo period) in today’s Okayama prefecture. There were about 60 swordsmiths who belonged to Mizuta school and Kunishige were the most prestigious smith name only selected sword makers were allowed to use in this school. During the Edo period, many Kunishige swordsmiths moved to other parts of Japan. There are two major groups in Kunishige swordsmiths during the Edo period. One is called Oyogo Kunishige school(大与五国重派), lead by Master Otsuki(大月)and the other is called Kono school(河野派) lead by Tameie(為家). Okayama prefecture is located near the Chugoku Mountains, where iron sands, one of the essential materials for making Japanese swords, were abundant. Furthermore, the swordsmiths in Okayama prefecture had close access to Yoshi River, where they could find water and charcoal. This geological location contributed to the swordsmiths to forge high-quality refined blades. We presume Bichu was quite active in sword-forging from ancient times. This blade is appraised as a Hozon Touken (保存刀剣) issued by NBTHK (Nihon Bijutsu Touken Hozon Kyokai: 日本美術刀剣保存協会). This authentication paper was only given to authentic Japanese swords, well preserved and high quality with artistic value. *Please keep in mind that there are a couple of Kitae Kizu on the blade. If you like to see the detailed condition, please feel free to contact us. 【Blade】 Cutting Edge Length (Nagasa) : 71.5 cm (28.1 inches) Curvature (Sori) : 1.2 cm (0.47 inches) Hamon : The crystalline structure which forms along the cutting edge of a blade as a result of the hardening process. Jimon (Jihada) : Visible steel surface pattern created by folding and hammering during forging process. Kissaki : Kissaki is the tip of the Japanese sword. Nakago : Nakago 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). Fuchi-Kashira : A pair of matching sword fittings that cover the upper and bottom parts of its sword hilt. The fuchi-kashira of this sword features a consistent wave motif. Waves are a powerful symbol in Japanese art and tradition, representing the strength of nature, resilience, and the passage of time. One of the most famous depictions of waves is by Utagawa Hiroshige, whose woodblock prints captured the beauty and power of the sea. In samurai culture, waves also symbolize endurance and adaptability, reflecting the warrior’s ability to face challenges with strength and grace. This design not only enhances the sword’s aesthetic but also carries deep cultural and philosophic

Mizuta School水田派

水田派は、室町時代末期の備中国に現れ、国重の名を代々受け継いだ一派である。松山、呰部、井原、荏原、新見など備中各地に拠を構えて作刀し、その勢いは古刀期から新刀期にまで及んだ。説示によれば、新見の国重は銘鑑により備後から備中新見荘に入り、後に松山城主三村家の刀工となったとされ、ほかに備後福山や河波でも作刀した工が知られる。新見住三郎左衛門尉国重、井原住の国重、英賀郡呰部住の大月左兵衛尉国重、水田住の大月与五右衛門国重など、地名と俗名を冠して長銘を切る工が代を重ねて連なり、国重と名乗る刀工が一門に圧倒的に多いことが、この派の大きな特徴をなしている。 作風は古刀期と新刀期とで趣を異にする。古水田と称される作には、腰の開いた互の目乱れを主調として小丁子や小乱れを交え、匂口が締まって小沸がつく、ややこせこせとした趣のものが見られ、茎先が大きく刃上りとなる点が見どころとされる。地鉄は小板目肌つみ、地沸がついて映りが立つ。新刀期の作になると、板目が流れて柾を交じえる鍛えに、小のたれや互の目を焼き、沸が深く、殊に荒沸が激しくつき、相州伝を強く意識した出来となる。地沸厚く地景太く入って湯走りがかかり、砂流し・金筋を頻りに見せ、棟焼がしきりにかかって皆焼風を呈する一群があり、帽子は掃き掛けて火焰風となり、あるいは焼深く一枚風となって長く返る。物打辺に矢筈風の刃を交えること、また小板目に小杢目を交え地沸微塵に厚くついて淡く映り立つ地鉄も、この派を見分ける拠りどころとなる。彫物を巧みにこなす工もあり、棒樋に倶利迦羅や梵字を施した大小の作が残る。 鑑定にあたっては、互の目や角ばる刃を交えた焼高い刃取り、矢筈風の刃、一枚風あるいは火焰風の帽子、棟焼の頻発といった水田特有の見どころが、相州・美濃に寄った実用本位の造込みと相俟って手掛かりとなる。沸の崩れや荒沸の激しさは、よく斬れる実戦の刀としての性格を物語る。在銘の確かな作は数が限られ、なかでも大月与五右衛門国重のごとく一門の他工にも稀なほど出来の優れたものが存する。新見の国重の一作は『光山押形』に所載し、附帯する古鞘に六代将軍徳川家宣すなわち文昭院の御陣刀であった旨が記される伝来の確かなものであって、備中の地に長く栄えた水田派の位置づけを今に伝えている。
