The Unryu of Ukai in Bizen, moved from Yamashiro and their swords were made in the Yamashiro tradition. Unju was the son of the second generation Unsho. Dated works extend from Bunna 2 to Oan 7 (1353 - 1374) during the brief Northern Dynasty. There are no dated examples of, the shodai Unsho, the founder of the school. However Unji, believed to be his son, is represented by a blade dated in Showa (1315).
I remember seeing a Juyo Nagamitsu on display at the Honbu with a three inch fukure in the hamon. I also handle a Tokubetsu Juyo Mitsutada with a fukure running almost the length of the blade. So if the work is good enough, some problems may be overlooked.
