  • The Effects of Starting a Farming Business Using the System of Community-Reactivating Cooperators: Case Studies from Ibaraki Prefecture

    Tamura Mio, Shimizu Yukari, Yamamoto Junko

    Journal of the Rural Life Society of Japan ( The Rural Life Society of Japan )  68 ( 1 ) 9 - 16   2025.03 [ Peer Review Accepted ]

    Type of publication: Research paper (scientific journal)

     View Summary

    <p>This research aims to show the effect of using the system of community-reactivating cooperators in starting a farming business. The method used is an interview survey of two cases that entered agriculture by using this system in Ibaraki prefecture. One was thinking about farming, the other was not originally thinking about it. We identified three positive effects: (1) The system attracts the latter to agriculture. The latter decided to start a business in agriculture through the activities. This result suggests that using the system may lead to expanding the possibility of securing human resources in agriculture. (2) The people can prepare for entering agriculture based on their idea because they can freely decide their activities. Also, the people were able to build relationships with people in other industries as well as agriculture and get trust through the activities. (3) The people can prepare to start farming by their own initiative. The reason is that their position is equivalent to civil servant, so they are not employed by active farmers. Their position led them to smooth networking with active farmers and deciding their management style themselves.</p>

  • Consumer Evaluations of Organic Agricultural Products on an E-Commerce Mall

    SHIBUYA Hitoshi, KATO Kosuke, YAMAMOTO Junko

    Journal of Food System Research ( The Food System Research Association of Japan )  30 ( 4 ) 255 - 260   2024

    Type of publication: Research paper (other science council materials etc.)

     View Summary

    This paper aims to characterize post-purchase evaluations of organic compared to non-organic agricultural products by applying text mining to consumer reviews on an e-commerce mall. We employ coding analysis to identify perspective differences and document scaling analysis to extract elements demonstrating divergent evaluation tendencies. The analysis revealed that health and safety expectations and interest in farmers were associated with positive evaluations of organic products, while environmental protection was a minor consideration. The evaluation criteria for attributes such as appearance and smell differed from those for non-organic agricultural products.

  • Understanding Research Trends and Topics on Organic Agriculture based on Scientific Literature in Social Science: A Scientometric Analysis using Citespace

    KATO Kosuke, YAMAMOTO Junko, KOBAYASHI Hiroaki

    Journal of Food System Research ( The Food System Research Association of Japan )  29 ( 4 ) 237 - 242   2023

    Type of publication: Research paper (other science council materials etc.)

     View Summary

    This study focuses on detecting trends and topics in social science research on organic agriculture. We applied scientometric methods, such as keyword co-occurrence analysis and burst detection to keywords assigned to scientific literature related to the social sciences from 2002 to 2021. As a result, various research topics on organic agriculture from production to consumption aspects were detected. Furthermore, recent trends in social science research were detected quantitatively. These trends included meta-analysis through case study accumulation and research topics related to organic agriculture and sustainability.

  • Feature Extraction of Consumers' Evaluation about Beef Including By-products Based on Online Reviews in E-Commerce

    Hattori Akihiko, Kato Kosuke, Yamamoto Junko

    Journal of Rural Problems ( The Association for Regional Agricultural and Forestry Economics )  58 ( 3 ) 141 - 148   2022.09 [ Peer Review Accepted ]

    Type of publication: Research paper (other science council materials etc.)

     View Summary

    This study aimed to explore consumer evaluations of beef by part, including its by-products. To achieve this, we analyzed online product reviews on Rakuten Ichiba (a major e-commerce site) from 2016 to 2019. We applied text mining analyses to these data in three stages: extraction of frequent words in the whole beef review to capture the overall characteristics; grouping of parts by correspondence analysis; and extraction of words that characterize each part to consider similarities and differences among parts or groups of parts. We found that for post-purchase evaluation criteria and consumption practices, several parts had some similarities, but there were also differences among several other parts and groups. Therefore, to further understand the needs of the consumer and promote the sales of beef, it would be advisable to consider the characteristics of each group of parts and each part individually.
