Tomato Consumer Behavior in Hino City, Japan: Application of Multiple Correspondence and K-means Cluster Analyses
GUNASEKARA HETTIGE SAMITHA LAKSHAN, SHIMOGUCHI NINA N., TERANO RIKA, SAVILLE RAMADHONA, HATANAKA KATSUMORI
International Journal of Environmental and Rural Development 15 ( 2 ) 157 - 166 2025
Language：English Publisher：Institute of Environmental Rehabilitation and Conservation, Research Center
<p>Japan is currently facing multiple challenges related to an aging society, including labor shortages in various sectors, especially in agriculture. Despite government support, new farmers struggle to discern and understand market trends, changing consumer behavior, and seasonal changes. This study focuses on tomatoes and aims to assist new farmers and producers in making strategic decisions by utilizing data science techniques to understand local market consumer behavior and trends. A questionnaire survey was used to identify consumer behavior based on demographic characteristics, consumer preferences, seasonal buying and consumption behaviors, spending price per purchase, and purchasing channels. We collected 316 valid data points using a questionnaire survey deployed in face-to-face interactions across multiple locations as well as online collection methods. Data was collected from May 01, 2022, to June 30, 2022. Multiple correspondence analysis and K- means cluster analysis were used to determine six consumer segments - convenient supermarket shoppers, premium salad shoppers, price-conscious tomato enthusiasts, diverse tomato tasters, quality-conscious shoppers, and gourmet tomato shoppers. The analyses revealed the unique characteristics of tomato purchasing and consumption behaviors, including variations in tomato type, consumption type, season, demographic factors, and preferred purchasing channels. This study further explored the factors influencing tomato purchasing decisions within each segment by integrating data-driven decision-making principles. This approach allows for actionable insights facilitated by understanding local consumers while empowering new tomato farmers to make informed decisions.</p>

Improving the Farm Business and Resilience of New Farmers: Case of a Greenhouse Tomato Farmer in H City, Tokyo
SHIMOGUCHI NINA N., TERANO RIKA, SAVILLE RAMADHONA, GUNASEKARA HETTIGE SAMITHA LAKSHAN, HATANAKA KATSUMORI
International Journal of Environmental and Rural Development 15 ( 1 ) 72 - 78 2024
Language：English Publisher：Institute of Environmental Rehabilitation and Conservation, Research Center
<p>Among new farmers, farming discontinuation within a few years is prevalent due to various issues, including difficulty in securing farmland, insufficient technology adoption, low income, and weak branding. In recent years, the importance of recruitment and support services for new farmers has been gaining recognition. Therefore, studies that can provide insights and innovations to improve the business operations and resilience of each new farmer are relevant and timely. Tomato is the most common fruit vegetable consumed fresh or processed in Japan. For new farmers, tomatoes are considered one of the favored high-value commodities for production. In response to the needs of a young female new farmer who ventured into greenhouse tomato farming in H City, Tokyo, this study aims to clarify the consumption and purchasing behavior, satisfaction and brand familiarity of randomly selected tomato consumers. We conducted a consumer survey from May to June 2022. Although we had 470 respondents, we only utilized responses from 213 consumer-respondents to capture the characteristics and preferences of those who experienced buying tomatoes from the selected farm (NF Farm). Through this case study approach, the survey revealed that supermarkets (31%) were the main place of purchase for fresh tomatoes due to convenience, followed by direct stores (28%) and unmanned stores (17%) due to both convenience and good product quality. Results indicated that cherry tomatoes were the most widely consumed across all seasons, while summer was the season with highest consumption of all tomato types, with prices ranging between 101 JPY and 500 JPY (1 USD = 133.9 JPY). After only 5 years in business, NF Farm seemed to have gained a fan base. Unfortunately, 63.8% of consumer- respondents indicated no knowledge of the farm logo. Most related the farm to the name of the farmer. Thus, there is a need for NF Farm to re-evaluate its farm brand (e.g., logo, farm name, labeling) so that it will be properly recognized even by its long-time customers.</p>

Identifying the Japanese Foreign Technical Intern and Training Program (TITP) in the Agriculture Sector and Its Outstanding Training Models: A Case Study of Indonesia
SYAUKAT FADHILLA IZZATY, HATANAKA KATSUMORI, SHIMOGUCHI NINA N., SAVILLE RAMADHONA

Language：English Publisher：Institute of Environmental Rehabilitation and Conservation, Research Center
<p>The Japanese government established the Foreign Technical Intern and Training Program (TITP) for developing countries, enabling trainees from these countries to improve technology, skills, and practical knowledge in an actual work environment and apply their skills when they return home. However, due to issues including improper wage payments and overwork, this approach has received harsh criticism from human rights organizations inside and outside Japan. Previous research has primarily focused on the negative aspects of this program, with little emphasis placed on its positive impacts. TITP is considered critical for Indonesia because it provides high-paying jobs for “unskilled” youth, accounting for more than half of the unemployed population. This research aimed to summarize the current general condition of the TITP, classify the different programs under TITP, and compare the socio-economic conditions of the alumni after finishing TITP and returning to Indonesia. Based on the findings, we can assert that the TITP in the agriculture sector has attracted TITP alumni to pursue a career in agriculture, thereby contributing to an increase in young farmers, desperately needed to ensure the future of Indonesia’s agriculture. The majority of alumni became farmer entrepreneurs. The average income of TITP alumni working in the agriculture sector was found to be more than three times that of the average Indonesian farmer’s monthly income. The main programs realized under the TITP and reviewed in the current study included the Industrial Training Program (ITP) and the Technical Intern Program (TIP). These programs were compared with the NT Farm (NTF) in Fukui, which is recognized for its exceptional training methodology, including entrepreneurship development training. All NTF alumni now own land, and their average income is slightly higher compared to that of the ITP and TIP alumni.</p>

Factors Influencing Adoption of Ecosystem-Based Adaptation Practices: The Case of Small-Scale Maize Farming in Morogoro Region, Tanzania
MOLLEL UPENDO SAITABAU, HATANAKA KATSUMORI, SAVILLE RAMADHONA, SHIMOGUCHI NINA N.
International Journal of Environmental and Rural Development 15 ( 1 ) 132 - 138 2024
Language：English Publisher：Institute of Environmental Rehabilitation and Conservation, Research Center
<p>Maize is the main staple crop in Tanzania; it is produced in almost all agroecological regions of the country, with production dominated by small-scale rain-fed farming. Maize production in Tanzania is constrained by climate change impacts such as rises in temperature, changes in rainfall patterns, and increases in plant diseases, insects, pests, floods, and droughts. Small-scale maize farmers have low climate change adaptation capacity, as the majority still use unsustainable farming practices such as monoculture, intensive tillage, and burning of crop residues, all of which increase the farmers’ vulnerability to climate change impacts. Sustainable farming practices, in particular Ecosystem-based Adaptation (EbA) practices such as the ones considered in this study, are believed to contribute significantly to restoring and conserving agroecosystems, increasing maize productivity and resilience towards climate change. This study aimed to identify the common EbA practices adopted by farmers in Tanzania and to determine the factors influencing adoption of EbA practices in maize farming. The study was conducted in the Kilosa district of the Morogoro region of Tanzania. Both primary and secondary data were used in the study. Primary data was collected through key informant interviews with the agricultural extension officers and a semi-structured questionnaire survey administered to 350 farmers. The T-test and the Tobit regression model were used for data analysis. Based on the T-test results, commonly adopted EbA practices included crop rotation, maize-legume intercropping, and improved seeds. Based on the Tobit regression analysis, farm size, household income, land ownership, access to climate information, labor, knowledge of EbA practices, and membership in the farmer field schools were found to significantly influence the adoption of EbA practices in maize farming. This study highlighted the importance of the government’s role in increasing EbA knowledge dissemination to the farmers through improving the training facilities in the farmer field schools and increasing opportunities for the farmers to have access to credit from financial service providers, allowing maize farmers to boost their income and become able to adopt more EbA practices.</p>

A Study on the Structure of the Fairtrade Value Chain: Focus on Certified Fairtrade Tea
NOGUCHI Takao, YASUE Hiroyuki, OMURO Kenji, MAMADA Michihiko, SHIMOGUCHI Nina N., KAWANO Yoichi, HARA Haruhisa
Journal of rural community studies 2023 ( 136 ) 1 - 17 2023.03
Language：Japanese Publisher：The Food, Agriculture and Rural Economics Society
<p>This study analyzed the value chain structure of certified fairtrade tea from the perspective of governance using global value chain analysis. At the stages of tea leaf cultivation, manufacturing, and shipping, “Captive” and “Hierarchical” types of governance are prevalent, with exporters taking the lead. To comply with fairtrade standards, the versatility and bargaining power of exporters are indispensable for the tea plantations.</p><p>At the tea leaf procurement and product sales stages, a “Modular” type of governance is common, with Japan’s certified fairtrade operators acting as the controlling body. In addition, transactions are somewhat more complicated due to the inclusion of fairtrade standards. However, certified fairtrade operators conduct procurement, product processing, and sales based on actual needs.</p>
