Japan government started special educational zone's operation in year 2003 then gradually legalized this system and promoted alternative education perspectives to public in year 2005. They expected the deregulation of related educational system could offer local educational bureaus and civilian organizations experimenting alternative education perspectives within existing frame work. The special truancy zone established by free school organization caught people's attention. Some free school's promoters seriously challenged the existence of school system and diplomaism but the establishment of private special truancy zone and its legalization through special educational zone's channel really conflicted with above concepts. The joint of special truancy zone into existing educational system led to imposed constraints from system as well as exchange of legalization and subsidy from government with its vanishing educational perspectives. Special educational zone, as experimental field of educational reform, had successfully improved student's learning capability as well as expanded multiple educating channels. However, it still could not effectively solve lower enrolled headcount issue but induced more educational expenses spent on this matter. From free compulsory education's perspective, special educational zone could not bring economic chain reactions but only duplicated and not creative practices. Issues such as instable income, lacking administration resources and high staff resign rate still seriously trouble this system. The abrupt legalization of special educational zone and promotion to public without associated measures already resulted in some practice's failures as experiment of educational policy. If continuous promotion and practice of special educational zone is required in the future, the associated regulations, measures, and proper evaluation systems must be established correspondingly.
