Okada Purifying Therapy is a type of energy therapy and is an important pillar of the Health and Wellness Program advocated by MOA. Previously, I introduced the results of a preliminary survey on the Okada Purifying Therapy conducted in 2006. 1. To summarize the contents, more than 70% of the people noticed the improvement of various symptoms after the treatment. 2. The improvement rate was the highest when women received treatment for 60 minutes or more. 3. Symptoms increased in a few percent after the procedure, and most of them improved within a few


Based on the results from the preliminary survey, we conducted a survey in 2007, and more than 60,000 people participated. The results were published in The Journal of Alternative and Complementary Medicine, the world’s prestigious magazine for Integrative Medicine (2012; 18 (4): 38-50). As far as I know, there have been no reports of a private organization conducting such a large-scale investigation. Therefore, we received a lot of encouragement from experts from all over the world. There is a Japanese report in the MOA Health Science Foundation Research Report Collection (2012; 16: 41-53), so please read it if you are interested.

1. Research purpose and research method

As I mentioned previously, this study was planned to investigate, firstly, how much the symptoms improved with Purifying Therapy. Secondly, whether there are conditions that make it easier for the symptoms to improve or increase.


Participants received the treatment for 30 minutes or more; and before and after the treatment, they evaluated the degree on a scale of one to five on: 1, body pain, 2, irritability, anxiety, depression (psychiatric symptoms), and 3, palpitation, cold hands and feet, dizziness (autonomic nervous symptoms).

2.Result of investigation

In the preliminary survey, there was considerable bias on the part of the participants, so for this survey, I asked the investigators, as much as possible, to have young people, men, and non-MOA members to participate. As a result, the bias was slightly improved and valuable data was obtained.

See Figure 1. Approximately 70% of the people answered that their physical pain, psychiatric symptoms, and autonomic nervous system symptoms improved after the procedure. The improvement rate was about 5% lower than that of the preliminary survey, which may be due to the difference in the participants. The percentage of participants with increased symptoms was 0.7% to 2.5%, and most of them improved within a few hours by watching the situation or adding treatment.

I investigated in more detail than the preliminary survey when the symptoms were likely to improve. As shown in Fig. 2, the improvement rate is the lowest when a person was recommended to receive a treatment for 30 minutes at his or her home. The result was that the improvement rate was the highest when the treatment is performed for 50 minutes or more at a place other than the participant’s home in anticipation of the effect of the treatment. But under all conditions, women always had a higher rate of improvement than men.

In summary, the effects of Purifying Therapy are influenced by the following four mental factors: 1) male or female, 2) home or other (place of treatment), 3) whether the treatment was performed in anticipation of the effect or was recommended by someone (motivation), 4) the treatment time depends on four conditions and whether it is just 30 minutes or more. However, the rate of improvement varies depending on the conditions, which can be seen in almost all treatments, including medicines and surgery. In other words, human beings are spiritual creatures. If one is convinced and receive any treatments, including Purifying Therapy, with a positive attitude, one’s ability to heal oneself (natural healing power) increases and more good results will be obtained.


Preliminary and main surveys gave almost the same results regarding the effects of Purifying Therapy on Japanese people; but what about people from other countries? In fact, the results differed greatly from country to country. The next time I will share about that. Please look forward to it.
