[Background] Moxibustion has contributed to better health outcomes of the Japanese people. But only a small number of reports are available regarding the current practice of moxibustion in recent years. We therefore surveyed moxibustion practitioners.[Methods] Through academic societies, professional organizations, and other associations related to the disciplines of acupuncture and moxibustion, practitioners were asked to respond to the questionnaire via Google Forms. [Results] Valid responses were obtained from 1,507 practitioners with the following demographics: 67.8% had been engaged in clinical practice for less than 20 years; 71.9% ran their own clinics; 43.6% belonged to academic societies; 69.3% belonged to industrial organizations, etc. The proportion of practitioners conducting various methods of moxibustion were as follows: 66.3% warming moxibustion and 53.4% for heating-through moxibustion, and regarding processed moxibustion, 79.5% included moxibustion with tube and 37.0% used smokeless moxibustion. Regarding the effectiveness of moxibustion, 98.9% responded as "highly effective" or "moderately effective." The proportion of respondents who experienced "patient's refusal of moxibustion" was 45.6% before patients experienced moxibustion and 33.2% after their experience. The patients refused it primarily because of "heat," "burns," and "uncomfortableness with smoke." Regarding the activities necessary to promote the spread of self-care moxibustion, "proving effectiveness through clinical research" (75.6%), "providing scientific evidence through basic research" (68.3%), and "awareness-building activities" (63.9%) were indicated among 1,495 respondents.[Discussion] The survey revealed that, due to the shift in societal awareness, there is also a shift in the use of moxibustion from direct moxibustion to more indirect moxibustion. Many clinical practitioners of moxibustion conducted the therapy because they considered it effective. The survey reconfirmed that heat, burns, and smoke represent major reasons why patients do not want to receive the moxibustion therapy. The challenging issues to be addressed for the purpose of spreading and developing moxibustion include maintenance of "safety," research to prove "clinical efficacy" and provide "scientific evidence," and "awareness-building activities."

Although it is not yet common, certified Kampo (traditional Japanese medicine) doctors and acupuncturists are cooperating with each other to provide traditional medical treatment for patients in some general hospitals in Japan. In other hospitals, however, Kampo and acupuncture-moxibustion have not been introduced, and doctors only treat patients using modern Western medicine. Many doctors must already be aware that modern Western medicine is not the only approach for the treatment of patients, but they do not make any efforts to improve the situation by adopting traditional medicine. Here, we give some examples of hospitals in which acupuncture treatments are routinely provided, having a favorable effect on both patients as well as the hospitals themselves. We believe that these examples give us a good opportunity to consider the future of an ideal medical system in which modern Western medicine and traditional Japanese medicine are successfully integrated.

Direct moxibustion has been a common used moxibustion method in Japan, has required moxa floss of high-quality, and has promoted the development of a moxa floss manufacturing method unique to Japan. At the same time in China, because indirect moxibustion and the stick moxibustion method has been commonplace, low moxa floss of a purified standard has been produced with a simple manufacturing method. However well-refined moxa has become available in China recently, and it is now more similar to that in Japan.
In this study, we investigated the difference between highly-refined moxa made in Japan and China based on reports from Japanese clinicians on the usability of moxa in firsthand practice. We performed a questionnaire survey with the country of manufacture blinded in 265 moxibustion clinicians. The number of valid responses was 164 (61.9%).
To the question asking what the difference between the two types of moxa was, 54.9% of clinicians responded there was “a little difference,” and more than half responded with “better usability” and “favorability” for the Japanese moxa. Of 119 clinicians who performed moxibustion, 85 (71.4%) selected “comfort” for the Japanese moxa.
We therefore conclude that Japanese clinicians recognize moxa refined with the Japanese manufacturing method as more suitable for direct moxibustion treatment.
