Reverend Tokuharu Miki (PL’s First Oshieoya-sama) said that, “Religion and science must accord.” When Reverend Tokuchika Miki (the Second Oshieoya-sama) established PL in 1946, he wanted to create opportunities for science and religion to work together following the understanding of the First Oshieoya-sama. 
  

The PL Hospital and PL Health Check-up Centres

In 1956, the Hoshokai Hospital (the predecessor of the PL Hospital) was opened following the belief that science and religion must accord. The present PL Hospital is a general hospital with modern medical equipment that serves PL Headquarters in Japan and the surrounding community. The PL Hospital doctors and nurses perform their sincere medical “art” by doing their best while relying on God. This approach to medical science is demonstrated by the remarkable results in patient recovery both physically and mentally. 

In 1970, the PL Health Check-up Centre Tokyo was opened, followed in 1971 by the PL Health Check-up Centre Osaka. These two centres in Japan are computerised and use state of the art methods referred to as “a three hour human dry dock” with modern auto-analysers. Each patient goes through this extremely detailed check-up and is then given a verbal and written summary of the results before leaving the centre. PL members going through the check-up centres and who are found to have illnesses are given consultations on the mental causes of their sicknesses. Another PL check-up centre has also now been opened in São Paulo, Brazil.

The PL Health Check-up Centres working hard to establish a preventative health care system are recognised throughout Japan for their unique thorough approach.

The PL Botanical Institute

The PL Botanical Institute established in 1970 has research facilities in Osaka, Japan and in Arujá, São Paulo. The Second Oshieoya-sama wanted to produce virus free plants and vegetables using meristem research to help the world’s poor people. He donated the first generation of virus-free potatoes to Brazil which have now become the ancestors of about half the present national production of potatoes. The institute is now conducting research to create new kinds of plants that can resist severe conditions such as soils containing salt. 

PL scientists and medical doctors are also working on a national Japanese project using a huge ion beam accelerator with the goal of developing an effective treatment for cancer. 
 

The Comprehensive Research Institute (CRI)

In 1966, ahead of the computer age, PL began to use computer technology to help analyse the relationship between mental habits and sickness. Today this department strives to show the scientific proof for the PL teachings, in addition to providing computerised support for all aspects of PL management and promotion. Also, through the support of the CRI, computers link all the PL centres (churches, branch churches and headquarters) throughout the world.
