Antique Japanese Sword Katana Signed by Sadatsugu with Tokubetsu Hozon Certificate 【Description】 This blade was signed by Echizen Jyu Hyuga no Kami Fujiwara Sadatsugu(越前住日向守藤原貞次) during the Kanbun era( 1624-1645: early Edo period ). Echizen Jyu means Living in Echizen province(today’s Fukui prefecture). Hyuga no Kami is the title given to this swordsmith. He belonged to Shimosaka school and is famous for being an apprentice of the first-gen Yasutsugu, the founder of Shimosaka school during the early Edo period. Who is Yasutsugu(His master)? It is said that the first-gen Yasutsugu was born in Shimosaka town in Shiga prefecture at the end of the Muromachi period(Late 16 century ). He built his career there until the beginning of the Keicho era(1596). However, he moved to Echizen province due to the relocation of the lord he served. He eventually was noticed and supported by Matsudaira Hideyasu, the third son of Tokugawa Ieyasu, who was the founder of the Edo government. Hideysu was the feudal lord of Echizen province during the early Edo period. With the support of Hideyasu, the first-gen Yasutsugu was able to establish the Echizen Shimosaka school. And his school’s fame became nationwide, so as Sadatsugu’s. Yasutsu was acknowledged by the first and second Tokugawa Shoguns, Tokugawa Ieyasu, and Tokugawa Hidetada. By Hideyasu’s recommendation, the first-gen Yasutsugu became Okakaekaji for the Tokugawa shogun family, meaning that he exclusively forged swords for the Shogun family. We believe Sadatsugu dedicated his career to helping the first-gen Yasutsu very closely while working on his creation. Considering how reputable Yasutsugu is, Sadatsugu’s craftsmanship must have been excellent enough to work with his master. This blade is appraised as a Tokubetsu Hozon Token(特別保存刀剣) 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, especially well preserved and high quality with artistic value. 【 Blade】 Cutting Edge Length(Nagasa) : 71.3 cm( 28.0 inches) Curvature(Sori) : 1.4 cm( 0.55 inches) For more detailed measurement of the blade/sword mounting 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 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 Sakura (桜, cherry blossom) pattern is designed for this Fuchi Kashira. These flowers are colored with golden metal and make a gorgeous look for this work. Cherry blossom is one of the seasonal things of spring, and it has been loved for a long time in Japan. Its pattern is designed not only for sword mountings but also for Kimono (着物, traditional Japanese costume) or furnishings. One theory says that the god of grain exists in cherry blossoms. Therefore, this flower pattern has been treated as the symbol of a plentiful harvest. Also, the Saya Gata (紗綾形) pattern decorates this Fuchi Kashira. It is a type of continuous design which many Samurais loved. According to a theory, This motif was brought to Japan from the Continent in the Momoyama period (1568-1600). Saya Gata pattern has a graceful appearance and represents the longevity and prosperity of the family. Due to this auspicious design combination, the cherry blossom and the Saya Gata patterns, you would feel as if it tells you its maker’s wish. Tsuka and

Shimosaka School下坂派

6 重要刀剣

茎にきられた黒い鉄こそ、この一門の最も確かな標である。鍛えは板目に杢が目立って交じり、刃寄り棟寄りに流れて肌立ち、地沸厚く、地景細かに入って、かねが総じて黒みをおびる。説明書はこれを繰り返し「越前がねの特色」と名指し、初代康継から重高・貞国・貞次に至るまで終始変わらぬ見どころとする。この一団は近江国坂田郡下坂郷を本貫とし、新刀初頭の越前にあって「下坂」を商標として用いた幾人かの鍛冶の集まりであって、説明書は一人の刀工とみるよりは一団とみるのが妥当とし、初期は康継をその代表者とする。初代康継は下坂市左衛門と称して越前に移り結城秀康に仕え、初め肥後大掾下坂と銘した。慶長十年から十一年にかけて江戸に召され、家康・秀忠両将軍の御前で鍛刀した褒賞として「康」の一字と三つ葉葵紋を茎にきることを許されて康継と改名し、葵下坂・御紋康継の名はこれに発する。以後は将軍家の御抱工として越前と江戸を隔年に勤め、本国打には越前住、江戸打には於武州江戸と切り添え、南蛮鉄を以南蛮鉄と添えた。肥後大掾藤原下坂の康継前銘は貞国・兼法・国康らと鏨運びも筆意も酷似し、今日なお銘振りによってしか分かち得ぬほど近い。 この一門の手は静かで、同時代の備前・美濃の華やかな新刀の多くに対置される。刃文は浅いのたれ・中直刃を基調に小互の目を連れて交え、小足・葉入り、沸厚く、荒めの沸がむらにつき、本工らしいばさけを生じて、金筋・砂流しが長くかかり、棟焼・飛焼さかんに、時に皆焼風となり、匂口は沈みごころとなる。帽子は浅くのたれて先尖りごころに三品風を呈し、掃きかけて長く返る。姿は身幅広く元先の幅差少なく重ね厚め反り浅い慶長新刀体配で、平造脇指は幅広寸延びとなる。彫物がいま一つの恒常で、彫口深く力強い越前彫・記内彫が一門の手を示し、不動三体仏・倶利迦羅・梵字・護摩箸・素剣を巧みに彫る。記内ら越前の彫物師の手によるこの深い浮彫は、説明書が地方の特色と名指すものである。一門が最も称えられる作域は相州写しであって、初代・二代ともに大坂落城に焼失した名物の再刃を試み、中でも貞宗写しを最も得意とし、各写しに自らの作風を加えて徒らに模倣せぬところに特色がある。手は系統と目的とで分かれ、貞国は直刃を得意として地がつんで精美に、貞次は越前関の系譜を引いて丁子の目立つ明るい現れを示し、重高は茎尻を栗尻とする点で一門の剣形と分かたれる。 収集家がこの一門の作に向かうべき所以は、その見分けやすさにある。黒く肌立った越前がね、ばさけた刃縁、縞がかる砂流し、長く掃きかける小丸の返り、そして深い記内彫が併さって、写した古作によってではなく一門自らの語法によって読まれる。中心に立つのは初代康継で、駿府滞在中の駿州打や名物写しを残し、駿府御分物の一刀は紀州徳川家に、号風雷神の刀は越前松平家に伝来した。嫡子二代康継は父風を忠実に継ぎ、継の字形以外では殆ど区別し難く、晩年は初代に劣らぬ域に達した。二代の後、家は江戸三代を右馬助、越前家を四郎右衛門が継いで両系に分かれ、同名は幕末まで両地に栄えた。江戸三代は鍛えがつんで綺麗に、匂口は明るく、直ぐの焼出しを置いて法城寺一派など当時の江戸物に近づく。後援者本多飛騨守成重の立葵紋が貞次や康継一門の優品に多くきられ、截断銘がその伝来を彩る。藤代は上々作から上作に位し、一門は名だたる蔵伝よりも在銘の指定刀を通して出会われる。市に現れるのは葵紋を切った在銘の康継、あるいは下坂貞国・貞次・重高の在銘作であって、根気をもって待てば折にふれ世に現れ、現れれば家康の葵紋下賜に発する越前下坂の確かな一口となる。
