The annual survey of Japanese Society for Dialysis Therapy Renal Data Registry (JRDR) was conducted for 4,396 dialysis facilities at the end of 2016, among which 4,336 facilities (98.6%) responded. The response rate of the 2016 survey was comparable with the past, even though it was the second year after the new anonymization method. The number of chronic dialysis patients in Japan continues to increase every year; it has reached 329,609 at the end of 2016. The mean age was 68.15 years. The prevalence rate was 2,597 patients per million population. Diabetic nephropathy was the most common primary disease among the prevalent dialysis patients (38.8%), followed by chronic glomerulonephritis (28.8%) and nephrosclerosis (9.9%). The rate of diabetic nephropathy and nephrosclerosis has been increasing year by year, whereas that of chronic glomerulonephritis was declining. The number of incident dialysis patients during 2016 was 39,344; it has remained stable since 2008. The average age was 69.40 years and diabetic nephropathy (43.2%) was the most common cause in the incident dialysis patients. The incidence of diabetic nephropathy has been stable for recent several years. 31,790 patients died in 2016; the crude mortality rate was 9.7%. The patients treated by hemodiafiltration (HDF) have been increasing rapidly from the revision of medical reimbursement for HDF therapy in 2012. It has attained 76,836 patients at the end of 2016, which were 21,503 greater than that in 2015. The number of peritoneal dialysis (PD) patients was 9,021 in 2016, which was slightly decreased from 2015. 20.3% of PD patients treated in the combination of hemodialysis (HD) or HDF therapy. 635 patients were treated by home HD therapy at the end of 2016; it increased by 63 from 2015.
