Description

This is an ubu, mumei katana attributed by the NBTHK to Mito Masakatsu, a student of Katsumura Tokukatsu, forged in Hitachi Province during the late Edo period. The blade is in outstanding, nearly flawless polish with a tight itame-hada jigane and a dignified suguha hamon. It is accompanied by a beautifully preserved period koshirae featuring a unified shōchikubai (pine-bamboo-plum) theme, making it ideal for both study and display.

Historical context

The Shinshintō revival

›

Around 1800 Suishinshi Masahide argued in his writings that the craft must return to the old masters’ methods: the fukkotō revival. His greatest successor Naotane worked convincingly in Bizen and Sōshū manners that had been dead for centuries.
