粟田口国吉

The Six Brothers of Awataguchi — Kunitomo, Kuniyasu, Kuniyoshi, Kuniie, Kunikiyo, and Kunitsuna — represent one of the great miracles of Japanese sword history: an entire family of masters, working in the same Kyoto district, each achieving the highest standards while sharing the distinctive Awataguchi aesthetic. Kuniyoshi, the specialist in tantō, stands as the bridge between the school's founding generation and its supreme master Yoshimitsu. That his work entered the imperial collection is no accident: the Awataguchi smiths were, from the beginning, the swordsmiths of the court, their location at Kyoto's eastern gateway placing them beside the institutions of imperial power. For the emperor to possess a Kuniyoshi tantō was, in a culture where the divine sword was among the Three Imperial Treasures, an act of continuity with the deepest roots of Japanese sovereignty. The Sannomaru Shōzōkan, opened to the public in 2023, now allows ordinary citizens to encounter this connection face to face.
