The Japanese Society for Laboratory Hematology (JSLH) was launched in 2000 and has been developed by a mutual collaboration of hematologists, medical technologists, and the companies involved in hematological laboratory testing. The aim of JSLH is the progress and development of laboratory hematology by academic conferences, periodic publication of academic journal, training and education (in the meeting, the journal, or the website), promotion of the standardization of laboratory hematology, and certification of the laboratory hematology specialists. Among 3 specialized committees organized for the standardization of laboratory hematology, the standardization committee on blood cell morphology has been dealing with the various projects on peripheral/bone marrow blood cells and normal/abnormal morphology. Another independent organization, the Japanese National Research Group on idiopathic bone marrow failure syndromes (BMF), has raised the importance of the dysplasia of myelodysplastic syndromes (MDS) and has been conducting the prospective registration, central review, and follow‐up study of MDS. This group recently proposed the grading system for diagnostic accuracy of MDS, and the detailed procedure of morphological diagnosis of MDS is presented in the specialized color atlas with typical photographs of various dysplasia. JSLH has also approved the grading system for diagnostic accuracy of MDS and adopted this standardized diagnostic system to the educational item for certification of the laboratory hematology specialists, aiming at a nationwidely expanding morphological evaluation of myelodysplasia. Further and significant progress in the standardization of blood cell morphology will be expected in Japan through the activity of JSLH.
