Originally, this Uda school is originally from Yamatokoku Udagun, therefore many have the characteristic of Soshuden jigane with many
activities in the ha such as kinsuji and sunagashi. The gorgeous Matsuhi hada(literary translated "Pine skin had") of Norishige is especially enchanting.
This piece is attributed as Naoeshizu in the past but currently judged as Kouda. There are especially some mix of mokume with jinie and chikei attached. The jigane is dark color with deep nioi suguha base konie is very nice. The sunagashi and kinsuji work of this piece is excellent too.
