Abstract
The seven necessary conditions for reliable nonprofit organizations (NPO) were put together through the discussions of NPO support center leaders across Japan. This guideline sets out the necessary organizational conditions through which nonprofit organizations, such as NPO corporations, can gain the trust of their beneficiaries and supporters, as well as society. The conditions were originally published in February 2004. This article reports on their historical background, process, contents, and an actual case study in Kumamoto Prefecture using the conditions as a method of self-evaluation for their training.
