Nihon Ki-in professional
3p 2020 (prize earnings)
He seems to have been rather unsuccessful in tournament play. There's no obvious evidence of him having ever won a game in a main tournament, only in preliminaries. Though if that's the case, how did he earn promotion at the start of 2020 based on prize earnings?  It's unclear.
As of 2021-11-22, Go Ratings ranks him as #632 of the ~900 professionals it lists.
