Supply systems for various public goods change with changes in socioeconomic circumstances.　Green spaces in urban areas such as parks and roadside greenery have various functions, including environmental preservation, landscape, recreation and disaster prevention.　Recently, many cities try to increase green space in both public-owned and private-owned areas.　Public-owned greeneries include urban parks with various facilities, roadside greeneries, riverside areas, agricultural parks, retention basin, public school sites, cultural facility sites, government building sites, and other public accommodations.　Private-owned greeneries include leased land parks, nongovernmental athletic fields, greenery around factory sites, greenery in commercial and business sites, private school sites, private gardens, and zoning sites designated by law or city regulations. However, to determine how and by which sector, public or private, these green spaces should be supplied, it is necessary to clarify the relationships between the characteristics of green space as public goods, which show non-excludability and non-competitiveness, and the supply of these spaces.　This study concentrates on the relationships between these characteristics and the supply of greenery.　The use and supply of green space in Saitama City, which has a large area and variety of greenery spaces, was examined through administrative documents. Consequently, we showed there are various green spaces supplied by various procedures.　Green spaces of non-excludability and competitiveness are supplied by the public sector.　Green spaces of non-excludability are supported by volunteers.　Greenery of excludability is regulated by administrations.　Characteristics as public goods of the use of greenery space appear to reflect city policies and citizen needs, such as necessities for revitalization of agricultural land and enthusiasm for sports activities.　Greenery supply systems need to be reconsidered as regional positive choices after due consideration of the characteristics as public goods.
