Aoi Art’s Comment: Chounsai Koretoshi was highly regarded in the Aizu domain of the Tohoku region. This sturdy tanto with nioi-deki choji midare was a favored piece. The koshirae likely belonged to a samurai of the domain, as indicated by the floral and insect motifs, which convey a gentle atmosphere.
