To evaluate the current state of the Onsen-Ryoho-Specialist (Broad Certified Fellow in Balneology, Climatology and Physical Medicine) training system, we surveyed the training facilities designated by the Japanese Society of Balneology, Climatology and Physical medicine (BCPM). Of the 24 facilities targeted by the survey, 21 responded (88%). Currently, the training curriculum for Onsen-Ryoho-Specialists consists of 8 units on diseases and 8 units on therapy methods. As shown in Figs. 1 and 2, it is difficult for a single facility on effectively cover all of these units. The most pressing need is to establish and implement a standardized curriculum across all facilities. Until now, each related academic society has selected training facilities based on its own criteria. Moving forwards, the review/accreditation body of the Japanese Medical Specialist Broad will make site visits to establish and review Onsen-Ryoho-Specialist training facilities. These efforts should lead to the development of fully qualified Onsen-Ryoho-Specialist training facilities.
