It is our great regret to inform you sad news that Dr. Minoru Imajima passed away in the early morning of 13 March in Sayama City, his hometown. He has been suffering cancer and has long been in the hospital. He was so enthusiastic about polychaete systematics and his passion made him bring his microscope to the hospital room and had continued his research and writing books until the very end. He just completed publishing the book “Polychaete Part 4” (in Japanese) and we were happy to see it. Masanori, Dr. Masanori Sato met him just one month ago, and he told me that he looked very fine at that time and communicated about the old habitat conditions of one species of Hediste. We all thank him for his great contributions to not only annelid world but also to systematic societies. We are sharing the pains with his family and friends. We are so sorry for not telling you sooner.
Waka and all the polychaetologists in Japan.
