Within the Bizen Osafune workshops of the closing Muromachi period, the body of smiths and their output that scholars group under the heading Sue-Bizen, the name Kiyomitsu (清光) was carried by a large number of hands. The setsumei consistently note that the swords signed in the Tenbun, Kōji, and Eiroku eras issue from Osafune in Bizen Province, and that the Hayami reference work enumerates roughly ten craftsmen who used common names (zokumyō) such as Gorōzaemon-no-jō, Magōemon-no-jō, Yosazaemon-no-jō, Hikobei-no-jō, and Magobei-no-jō.
