The first gen. KUNISUKE was born in Kanbe town, Ise province (now in Suzuka-city) and assumed his birth was very early of Keicho period (very early 17th century) it is guessed from the age difference between 2nd generation. He had moved to Kyoto and became a disciple of well-known great master Horikawa KUNIHIRO on about 16-17th year of Keio (A.D.1611-1612) on the later years of master KUNIHIRO. Therefore it has been understood that he studied under the tutorship of Echigo-no-kami KUNITOMO. There is something persuasive in his workmanship that his signature and forging/tempering technique is pretty similarly each other. After master KUNIHIRO passed away, he again moved to Osaka where was lively and humming with business then enjoyed Kawachi-no-kami title from the Imperial Court in early Kanei period. He had refined KUNIHIRO's workmanship and sublimate it into beauty of art that fascinated Samurais or merchants in Osaka. The subject brave and heroic wakizashi would be made in his middle aged around early 30 plus years old, strongly influenced by the work of heroical Izumi-no-kami KANESADA (the best cutting performance) style and certainly successfully expressed. Forging mark became delicately fine and steel is selected carefully where glittering ji-nie metal granules spread over uniform in Hiraji surface. In the interior of temper, there works with sunagashi and kinsen like a mumur of brook and entire temper is filled in with deep nie and nioi mist. Sword shape is wide on base extremely and very thick in kasane leading to a large and heroical tip, which is very impressive and can still feel a medieval brave samurai spirits right after the Final Battle Osaka Natsu-no-jin between Tokugawa and Toyotomi. The first gen. KUNISUKE was passed away in the 30th, the fifth month, fourth year of Shouho(A.D.1647)
