Deletion of Shōrinji-ryū Karate-do Renshinkan

Comment: I looked carefully at the Japanese sources I found. They show mostly unsubstantial coverage. I was hoping to find something to fit  (national and international activities, check; information can be verified by multiple, third-party, independent, reliable sources, fail). It's mentioned a lot. It definitely exists and has many students, but it doesn't seem to have its own in-depth coverage in reliable sources
