Born in Kyōwa 3 (1803) at Shirakawa in Ōshū, Koyama Munetsugu (固山宗次) carried a smith's name read variously in the setsumei as Munobei or Sōbei, working under the art-names Issensai and Seiryōsai. He came up alongside elder brothers Munehira and Munetoshi, and although his teacher is traditionally given as Katō Tsunahide, the NBTHK readers repeatedly note that the hand of Katō Tsunatoshi shows through his work more plainly.
