The twentieth century nearly killed the craft twice: wartime distortion, then the occupation ban. The NBTHK’s founding in 1948 and licensed forging from 1953 rebuilt the sword as an art, crowned by Living National Treasures and the mukansa rank.
(The polish is by the Living National Treasure Fujishiro Matsuo Sensei) The swordsmith Osumi Shumpei was born in Gunma Prefecture in Showa 7 and entered the school of the Living National Treasure swordsmith Miyairi Akihira in Showa 27. From his master, he primarily mastered the Yamashiro-den and Rai Kunitoshi forging methods, and thereafter, using old masterpieces from the Heian period to the Kamakura period as models, he devoted himself to the study and refinement of the Bitchu Aoe suguha style. In the Shinsaku Meito Ten, he received the highest award, the Masamune Prize, three times: at the 10th exhibition in Showa 49, the 12th exhibition in Showa 51, and the 14th exhibition in Showa 53. In Heisei 9, he was designated a Living National Treasure. This tachi is a representative work of a Bitchu Aoe tachi. It is a tachi that faithfully copies the Bitchu Aoe of the Kamakura period. The sugata shows a magnificent Kamakura mid-period tachi form with high koshizori, wide motohaba, and wide sakihaba, and the jigane is a wonderfully spirited and splendidly forged ko-itame hada that is well-packed. The hamon is a suguha with gunome, yo, and ko-ashi appearing within the ha, showing excellent hataraki within the ha and splendidly copying Bitchu Aoe. The period of this tachi's production was when the swordsmith was at the absolute peak of his skill, and it is a tachi that can only be described as magnificent. The polish was performed by the Living National Treasure Fujishiro Matsuo Sensei, and the polish itself is also precious. Please by all means enjoy this precious tachi by the Living National Treasure swordsmith Osumi Shumpei, which must be cherished for future generations.
