From Aoi Art: Gassan is an old work (before Nanbokucyou, the sword stem was not inscribed. The inscription is in the middle of the Muromachi period. Ko-Gassan has few in-brand items and is said to have been unbranded before that. This work is judged to be around the middle of the Muromachi period because it is inscribed. It is a solid work, so I highly recommend it. It is also common in Gassan this time.
