The purpose of this study is to explore the possibility of developing alternative schools into a private management of public school in the future. In order to obtain legal status, alternative schools have changed their operating modes to NPO and educational corporation over the years. However, NPO do not have the capacity for rights, and those who meet the conditions for establishing an educational corporation are the minority. Because Japanese educational environment emphasizes public principles, and alternative schools must be public in nature. The study adopted in-deep-interview for data collection. The main findings include: 1. The educational environment is a city with a high degree of autonomy and high education expenditure. Based on the management contract, reuse unused school as campuses. 2. The conditions for setting up and bidding are not clear, many parties have questioned the necessity of expenditure, and the practice of transforming into a school organization has not fully met the needs of alternative schools. 3. Private management of public schools consider the balance between public and private interests. But there are shortcomings such as unstable contracts, unstable public subsidies, and loss of school autonomy. 4. Unless the alternative school is transformed into a school organization and has sufficient funds, the public unit will not choose to cooperate. By far, there are no practical examples in Japan since there are many obstacles in internal or external environmental factors that to be overcome.
