This study aims to identify the success factors of businesses related to agricultural production, which are expected to be an initiative for increasing farmers’ income. To this end, we analyzed the Chiba Prefecture 2020 Agricultural Census of individual data, and find that less than 10% of farmers were engaged in related businesses, with most in retail trade and agro-processing. The following farm characteristics were also correlated with sales of related businesses: engaging in export and renewable energy generation, growing horticultural crops, having young business owners, and recruiting successors and female workers.

The sudden rise in chemical fertilizer prices has highlighted the need to focus on utilizing sewage sludge as fertilizer; however, consumer understanding is required as current utilization rates remain low. Consumer awareness regarding fertilizers differs across countries; thus, it is necessary to clarify consumer evaluations of sewage sludge fertilizers in Japan. This study’s survey results employ a price sensitivity measurement, showing that sewage sludge fertilizer is rated lower than other fertilizers, and evaluations differ depending on consumers’ knowledge. Thus, improving consumer understanding can increase demand. Furthermore, appropriate risk communication becomes an essential area for future study.

This study aims to classify farms into groups based on trends to examine the challenges they face by conducting a questionnaire survey of JGAP farms (rice or livestock) regarding their awareness, efforts, and evaluating of their effectiveness related to environmental conservation. Farms with higher ratings tended to be rice farms, were newer in terms of certification, and to have acquired other certifications. As measures to improve issues, we propose to increase awareness of environmental conservation, improve the evaluation of environmentally friendly actions, and improve the quality and quantity of efforts.

This study aims to clarify consumer preferences for tea made from the unused parts of Japanese Angelica (Tohki) leaves. The findings indicate that albeit elderly women with high health consciousness and older individuals with environmental awareness show interest in products derived from Tohki leaves, they express concerns about the safety and efficacy of such items. Enhancing scientific evidence and transparency is crucial for improving trust. Choice experiments reveal that indicating health benefit label and utilizing unused part label increase purchase intent. Marketing strategies that address both health and environmental awareness may boost purchase probabilities.

This study clarifies the economic diversification activities of farmers’ markets in Taiwan and examines the direction of management development. The results show that economic diversification activities are organized into assortment-type activities focusing on primary processing and product development on the one hand and service activities emphasizing experience and interaction on the other. In recent years, public support has been pushing for the reopening of farmers’ markets. It is believed that farmers’ markets are moving toward incorporating food and agriculture education and service activities and becoming centers for local exchange.

This study investigated the relationship between exterior design and the perceived “ease of entry” for privately-owned restaurants. The findings yielded two main conclusions. First, consumer criteria for evaluating ease of entry varied depending on whether the establishment served only food or both food and beverages, even for the same restaurant. Second, women tended to be more conscientious about assessing clientele, often considering whether the restaurant aligned with their sense of appropriateness before deciding to patronize it.

This study examined the ethical determinants of consumers’ willingness to pay (WTP) for livestock products prepared while ensuring the animal welfare. The analysis used structural equation modeling with random parameter logit models. The Results showed that consumers felt generally positive about animal welfare–certified butter. Additionally, both utilitarian and obligatory animal ethics, which contradict each other in traditional ethical theories, were found to coexist in consumers and increase their WTP for animal welfare–certified butter.

This study aims to examine internal and external motivations underlying Taiwanese farmers’ willingness to transition to organic farming. The empirical analysis is based on a multinomial logit model and suggests that internal motivations, particularly those related to personal skills and educational background, form the foundation for considering organic farming. However, external motivations, especially environmental considerations, play a supportive yet crucial role in reinforcing this decision.

The economic effects of beef cattle production on the local economy are not limited to the beef cattle sector; backward and forward linkage effects ripple through other sectors. We evaluated the linkage effects of Wagyu beef production in Shiga Prefecture. The findings are: (1) the backward and forward linkage effects are 10,950- and 14,324- million yen, respectively, which are 1.18- and 1.54-times the value of Wagyu beef production; (2) the backward linkage effect rippling within the prefecture is limited to 15.0% of the total effect, whereas the forward linkage effect rippling within the prefecture is 76.7% of the total effect.

The impact of rising oil prices on agricultural production in Japan remains uncertain. This study examines how increasing crude oil import prices influence agricultural production using an inter-regional CGE model. The findings indicate that agricultural production increased in Hokkaido but remained unchanged in Tofuken, which encompasses all regions in Japan excluding Hokkaido. Overall, agricultural production in Japan grew, driven by a decline in imports and an increase in exports. To enhance the agricultural sector's resilience to external factors such as increasing oil prices, it is essential to steadily expand agricultural product exports.

This study examines the promotion of sake-brewing rice production, which has been developed independently. A survey of farmers and a sake-brewing company in Kochi Prefecture was conducted to identify the factors contributing to this situation. The survey revealed that the production infrastructure is well-established, and there is a sufficient price differential compared to edible rice. Production is encouraged because of the benefits for the producers. In such cases, fostering a stronger relationship with the sake-brewing company facilitates reaching a consensus on quality improvement and supply-demand adjustments.

This study determines customer acceptance of farmers' practices, such as reduced pesticide and chemical fertilizer use, biodiversity conservation, and ICT adoption, through factors influencing rice repurchase. The BWS results indicated that taste, cultivation methods, and farmers are crucial repurchase factors, with taste significantly more important than others. Good taste is essential for customers to accept farmers' practices. Customers emphasizing cultivation methods and farmers' practices showed a 6-13% higher WTP than the current price, whereas price-sensitive customers had a lower WTP. Customers who value cultivation and practices had higher agricultural knowledge and awareness, suggesting that enhancing these aspects could increase WTP.

This study aims to reveal the reality and characteristics of alternative meat consumption in Japan. It also aims to identify factors that promote the diversification of alternative protein sources. We analyzed consumer attributes using logistic regression on the purchase history data of plant-based meat (PBM) products and consumer surveys conducted between 2021 and 2022. The results indicated that urban consumers, diabetics, those passionate about food, and health-conscious and savings-oriented individuals exhibited higher PBM purchase probability. Conversely, young individuals, students, individuals with a high level of other-comparability, and cautious and efficient purchasers showed lower PBM purchase probability.
