説明
「刀姿 sword figure」
鎬造り庵棟、身幅尋常重厚く、鳥居反り中鋒。茎は生で鑢目は筋違い、茎尻は栗尻。
The blade is in shinogi-zukuri with an iori-mune (rounded ridge), having a standard width and a thick, heavy feel, with torii-zori (arched curvature) and a chu-kissaki (medium-sized tip). The nakago (tang) is ubu (unshortened), with sujikai (slanting) yasurime (file marks), and the nakago-jiri (tang end) is in kuri-jiri (chestnut shape).
「地鉄 jigane」
地鉄は小板目の細かな肌に板目ごころの肌が交じり、地沸が微塵に厚く付き、地景が細かによく入っています。
The jigane (steel surface) features a fine ko-itame (small wood grain) pattern interspersed with areas of itame (wood grain). The surface is densely covered with minute ji-nie (martensite crystals), and intricate chikei (dark lines) are well-present throughout.
「刃紋 hamon」
刃紋は全体的に焼きが高く、起伏があり、丁子に互の目、小互の目、角ばる刃や尖りごころの刃が交じっています。刃紋には頻繁に足や葉が入り、匂出来となっています。部分的に粗い沸（にえ）のむらが見られ、所々に小さな飛び焼きもかかっています。釯子は乱れ込み、小丸に尖りごころを持って返ります。
The hamon (temper line) is generally high and displays undulations, with a choji-like (clove-shaped) pattern intermingled with gunome, small gunome, angular peaks, and pointed elements. There are frequent ashi (downward lines) and yo (small, leaf-like lines) in the hamon, resulting in a nioi-deki (hazy) appearance. In certain areas, there is coarsely clustered nie (martensite crystals) and small tobiyaki (spots of temper) in various places. The boshi (tip temper line) is midare-komi (irregular), returning in a pointed fashion with a small circular turnback.

Nisshu-ju Kunimasa, whose real name is Ichiro Matsuba, was born in 1959 and resides in Hyuga City, Miyazaki Prefecture. He began studying kendo at age 11 and later learned iaido and karate. In 1983, he was inspired to enter swordsmithing after commissioning a sword, leading him to apprentice under master swordsmith Yasuhiro Kobayashi, the creator of the Tetsuken sword. He continued his training with Hiroki Ando, an elder apprentice in Okayama, and obtained his swordsmith license in 1989. The following year, he exhibited at the New Sword Exhibition and was selected. Since then, he has received numerous awards, including the Effort Award, Excellence Award, Special Award, Kanzan Award, Kunzan Award, and President’s Award, earning the distinction of being a mukansa (exempt from appraisal) swordsmith.
Kunimasa is renowned for his Bizen-den Osafune Nagayoshi and Sue-Bizen reproductions. Known for forging highly functional, sharp swords, he is also a prolific author and is highly respected not only in Japan but internationally, recognized as a prominent figure in the martial arts world.
This piece is a Nagayoshi reproduction, a style Kunimasa excels at, and is a splendid tachi that exudes vigor and spirit.
The oshigata is from a work that won the Chairman’s Award from the Nihon Bijutsu Token Hozon Kyokai (NBTHK) at the 2012 New Master Sword Exhibition and was featured in the June 2012 issue of Token Bijutsu magazine. Following this, Kunimasa’s award-winning works were also featured in the June issues of 2013 and 2014, achieving three consecutive years of publication.
