    The annual survey of Japanese Society for Dialysis Therapy Renal Data Registry (JRDR) was conducted for 4,458 dialysis facilities at the end of 2018 among which 4,402 facilities (98.7%) responded to the facility survey and 4,222 facilities (94.7%) responded to the patient survey. The number of chronic dialysis patients in Japan continues to increase every year; it has reached 339,841 at the end of 2018 and the prevalence rate of the dialysis patients was 2,688 per million population. The mean age of the prevalent dialysis patients in the patient survey was 68.75 years. Diabetic nephropathy was the most common primary disease of the prevalent dialysis patients (39.0%), followed by chronic glomerulonephritis (26.8%) and nephrosclerosis (10.8%). The distribution of diabetic nephropathy in primary disease was the same as in 2017 and has become plateau. The number of the incident dialysis patients during 2018 was 40,468; it was decreased by 491 from 2017. The average age was 69.99 years and diabetic nephropathy (42.3%) was the most common cause in the incident dialysis patients. The distribution of diabetic nephropathy in the primary disease did not change for recent several years. 33,863 patients died in 2018; the crude annual mortality rate was 10.0%. The 3 major causes of death were heart failure (23.5%), infectious disease (21.3%) and malignancy (8.0%). The patients treated by hemodiafiltration (HDF) have been increasing rapidly since 2012. It has reached to 125,793 patients by the end of 2018, which was accounted 37.0% of all dialysis patients. The number of peritoneal dialysis (PD) patients was 9,445 in 2018, which has been slightly increased since 2017. 19.7% of PD patients treated in the combination or hybrid therapy with hemodialysis (HD) or HDF. 720 patients were treated by home HD therapy at the end of 2018; it increased by 36 from 2017. In the 2018 survey new items were added to the conventional items such as treatments for diabetes, prevalence of dementia, daily physical activities and regular exercise habits. Further analysis of these items will be reported in another form in the future.
