A 2013 empirical analysis of how location shapes demand for 'experience farms' (taiken nouen, farmer-led pay-to-participate allotments) in Tokyo, Japan, combining a user survey with small-area census statistics (Journal of Rural Planning Association 32, Special Issue, pp. 323–328). Most users lived within 2 km of the plot, and roughly 0.5% of residents within 250 m became users. Nearby competing experience farms reduced demand at more distant sites, whereas adjacent conventional allotment gardens showed no competitive relationship. For an operator this means the catchment is narrow and neighbouring facilities of the same type divide the same demand, so siting largely determines whether the operation works. The paper does not analyse fees or profit and loss.

This study examined the management characteristics of direct farm sales outlets and the role of agriculture in urban areas, using pear farmers in Inagi City, Tokyo, as an example. Field surveys confirmed a decrease in pear picking activities and a high ratio of direct sales and home delivery. While familiarity with agriculture has increased due to farmers' cooperation in agricultural experience learning and the establishment of many community gardens, a limitation was identified: to convey the value of urban agriculture to those with low interest, the enhancement of pear picking, allowing easy interaction with farmers on farmland, is required.

The Santome Area in Saitama Prefecture has practiced circular urban agriculture utilizing plain woods for 300 years, but urbanization, particularly in Kawagoe City and Tokorozawa City, is causing a significant decline in farmland and plain woods. While the Ministry of Agriculture, Forestry and Fisheries and Saitama Prefecture promote urban agriculture and plain wood preservation, the plain-wood-utilizing circular urban agriculture in Santome Area faces specific problems. This paper identifies land systems, including taxation, as a central issue among these problems and examines the possibility of integrated preservation for farmland and plain woods.

This study in Japan aimed to identify the actual amount of agricultural production by measuring harvested products from two urban agricultural gardens. It found that production from an 'experience farm' was sufficient for annual household consumption, while allotment gardens could not reach these amounts. At the district scale (500m radius) in this study, urban agricultural gardens could cover more than 10% of all vegetable consumption by urban residents.

This report proposes a system to support city farmers' businesses by bridging the information gap between consumers and farmers, aiming for international export. The system provides consumers with information on city farmers' locations, vegetable quality, and production processes, while enabling feedback for farmers. The proposed system is projected to yield a net present value (NPV) of 5,300,000 yen in four years, starting in Tokyo and expanding to other regions and developing countries.

This study evaluated the benefits of Kleingartens (stay-type allotment gardens) for local municipalities in Japan, using data on investment, maintenance costs, and user fee revenue. A main finding is that municipalities, on average, incur a considerable deficit, with a typical Kleingarten having an estimated annual deficit of approximately 240,000 yen. The study concluded that it is difficult for municipalities to achieve profit by providing Kleingartens, even with marginal improvements from increased user fees.

Urban agriculture in Japan faces problems such as farmland reduction, farmer aging, expansion of abandoned cultivated land, and environmental pollution from livestock waste or agricultural chemicals. Urban agriculture can contribute to improving urban quality of life by supplying agricultural goods, creating landscapes, ensuring land conservation, and providing environmental benefits like biodiversity conservation. However, these issues pose challenges to the economic viability of urban agriculture.

This paper discusses the importance of not only conserving urban green spaces but also utilizing them to convert environmental resources into environmental assets. It emphasizes the need for role sharing and collaborative relationships between citizens and local governments to establish such utilization systems. Examples from Japan's 'Satoyama' conservation and Open Garden activities, along with U.S. community gardens, offer suggestions for developing these systems.

This exploratory study examines the Seikatsu Club's experience in Japan, which operates based on Community Supported Agriculture (CSA) and Sanchoku systems. These movements foster direct relationships between organic consumers and Japanese organic rural producers, who are part of social networks and aligned with sustainability principles. This approach contributes to more sustainable solutions for society by emphasizing new food consumption patterns and valuing consumer cooperatives.

This paper studied the Community Supported Agriculture (CSA) movement in the USA and Europe to provide ideas for establishing and promoting CSA in Korea to support organic agriculture. In a CSA system, farmers grow food for a group of shareholders who pledge to buy a portion of the farm's crop for the season. This arrangement provides growers with upfront cash and higher prices by eliminating middlemen. CSA shareholders expect organic farming to protect the environment, maintain soil fertility, preserve diversity, recycle resources, maintain organic food integrity, and develop new technologies considering long-range social and ecological impacts.

This paper analyzed the Minuma Fureai Garden in Kawaguchi City, Saitama prefecture, finding that its operation costs exceed annual income from user fees (15,000 Yen/person/year), with municipal subsidies covering 18% of total income. While land use regulations keep rent low, deregulation could threaten the garden's existence. A user survey revealed 70% of users were over 50, and 60% re-applied after a one-year contract, though this varied by distance.

Since the 1991 amendment of Japan's Agricultural Land Act, agricultural land in designated urban areas has been divided into two categories: land conserved for agriculture and land available for residential use. This study investigated the state of allotment gardens in several such urban areas, focusing on whether the land was designated under the Agricultural Land Act and various related acts governing the establishment of allotment gardens. It clarified the resulting differences in residential-land development potential and farmers' economic conditions between the two categories.

This study examined the future of allotment gardens in Ichinomiya City, Aichi Prefecture, by interviewing 20 landowners regarding land ownership and land use. Allotment distribution expanded into marginal urban regions, with new allotments concentrating in frontier areas. While most landowners were satisfied and intended to maintain allotments, those in urbanization promotion areas faced financial difficulties due to high taxes and motivation for land use conversion, indicating that allotment management will fail in these areas.

This study aimed to gather ideas about desirable physical characteristics and management of allotment gardens in an urban area. Standardized questionnaires were mailed to 660 subjects, with 345 responses received. The results clarified current user attributes and usage situations, proposing future improvements regarding traffic means, distance, contract terms, use size, cultivation guidance, facilities or equipment, use charge, and services for urban allotment gardens.

This study explained the reasons for non-cultivation in urban agricultural promotion areas and examined future subjects for conserving normal farmland surrounded by urbanization promotion areas. The occurrence rate of wasteland and infringement on agricultural land diversion in non-cultivated land differed according to city planning regulations and cultivating forms. The reasons for non-cultivation were found to be greatly related to farmers' workers, land ownership scale, and planning law, with owners of large landholdings who had no workers due to advanced age showing little intention to maintain agricultural operations or conserve farmland.

This paper examines the public perception of urban agricultural land as valuable open space in urban fringe areas. The study found that urban agricultural lands are considered valuable "green" spaces, with orchards (mainly persimmon trees) and farms being particularly highly evaluated. These positive perceptions were observed in both agricultural and nearby residential areas.

This 1988 report describes changes in Tokyo's agricultural structure driven by urbanization alongside the state of urban residents' diets. Labor and farmland shifted from Tokyo's special wards to the Tama area, where intensive cultivation of fresh produce such as vegetables was concentrated, while in mountainous districts agriculture was combined with forestry. Cultivated land had shrunk by about 60% over the preceding 25 years, and the number of full-time farm households had fallen by 70%, while part-time farm households roughly doubled. Taking advantage of proximity to a large consumer market, 118 vegetable species were cultivated, with production of daikon radish, spinach, and komatsuna increasing year on year. Self-sufficiency rates for key products were 12.7% for vegetables, 7.2% for milk, 3.4% for eggs, and 2.4% for meat. In the urban diet, average nutrient requirements were largely met, though calcium was somewhat lacking and vitamins B1 and C slightly insufficient. Intake of beans, seafood, and vegetables was low by food group, and average daily salt intake was 13.4g, above the 10g target. Eating out and skipping meals were relatively uncommon overall, but skipping meals — especially breakfast — was more common among high-school-age students and older.
