Eco-labeling schemes have been practiced in Japan to support eco-friendly farmers. Many previous studies have examined consumer preference on rice with eco-labeling which certifies its cultivation method. Most of those investigations, however, cannot sufficiently consider the variation of consumer preference. The objectives of this study are (1) analyzing the consumer preference about information on cultivation method and farmer, considering preference heterogeneity and (2) discussing the character of each consumer preference group. To achieve our purposes, we had an online questionnaire including a choice experiment and conducted latent class model estimation. The main outcomes are as follows. First, consumer preference on cultivation method, rice brand, and information on the farmer are heterogeneous. Second, consumers are likely to prefer the information on the cultivation method to information on the farmer. These results suggest to current eco-labeling schemes the importance of targeting a particular consumer group and providing proper information to each consumer group. Our results also suggest that consumers who prefer the information on the farmer are potentially becoming purchasers of conservation-agricultural products.

The objective of this study is to clarify how modification of the dairy herd can improve the performance of automatic milking systems in Hokkaido. It is focused on the refuse time and milk flow speed, and calculates the daily milk yield and profit, by eliminating the nonconforming cattle and introducing new cattle. From the results, it is possible to secure additional milking time by changing the dairy herd to speed up the milk flow rate. It is found that milking efficiency can be improved. This is more effective than cattle culling to reduce the number of refusals.

This study aims to reveal the determinants of Chinese and Korean tourists' satisfaction and intention to revisit Japan. To study these issues, we assumed that the performance evaluations for destination attributes, such as "Eat Japanese food" and "Shopping," determine tourist satisfaction and intention to revisit. The main results are as follows : First, favorable performance evaluations for "Eat Japanese food" and "Shopping" have statistically significant positive effects for overall satisfaction and intention to revisit. Second, young tourists tend to get higher tourist satisfaction than old tourists, so that we show the efficacy of promotion for young tourists.

This paper sheds light on spatial disparity across agricultural communities in Japan. In the remote and marginal areas, maintaining agricultural activities is increasingly difficult, thereby casting doubt on the sustainability of agricultural communities. Beta convergence tests are employed to determine whether the disparities of (1) the number of farmers, (2) land use, (3) the revenue per farmer, and (4) the number of community activities tend to decline or not. Our regression analysis supports the presence of Beta convergence for most variables, implying that there is no threshold below which agricultural communities inevitably disappear.

In Shichigahama Town, Miyagi Prefecture, where a tsunami struck, farmland is accumulating to large farmers rapidly because of the retirement of affected farmers. Intermediary institutions that manage farmland are utilized for farmland accumulation there. The reconstruction assistance policy contributed to the creation of new principal farmers. But they couldn't use the land efficiently because farmers avoided the prolonged debate about land use adjustment. Mowing work concentrating on large farmers may prevent the continuance of their farming. It is necessary to support planning on efficient land use and role sharing of mowing work among farmers and farmland owners.

In Hokkaido, the largest dairy prefecture in Japan, further reductions in the number of dairy farmers may cause rural communities to collapse. Therefore, in order to understand exactly the exit factor for dairy farms, we analyzed linked data from the 2010 and 2015 census of agriculture descriptively and quantitatively. As a result, we discovered that each region in Hokkaido has unique exit factors. This means that conventional unified policies will not work in many areas. We therefore need to formulate countermeasures against exit of dairy farmers appropriate for each region with reference to this study's results.

The objective of this study is to examine whether land consolidation projects (LCPs) facilitate land rental in agriculture. The Japanese agricultural policy has long been aiming at consolidating small-scale farms into sufficiently large size farms. A theoretical model in this paper predicts that the LCPs increase the demand for farmland on both lessors and lessees, which obscures the effect of land transactions between them. Using data collected by the author from Kyoto Prefecture, this paper measures the effectiveness of the LCPs on land rental. My empirical result shows that the LCPs have no causal effect on land rental, which is not consistent with previous studies in the relevant literature.

We revealed the change of consumption behavior regarding game meat and the factors by analyzing the association with the change of consumer awareness, knowledge, attitude and behavior toward the information. We collected the data by questionnaire survey in 2017 and 2018. The results are as follows. First, the number of consumers who have re-consumed game for a year is 27%. Second, in comparison with a year ago, consumers who re-consume game have more knowledge about the place where game is supplied. Third, such consumers do not only notice but also actively collect game information.

The purpose of this study is to try to measure the impact of climate change caused by global warming on the regional economies with agriculture and the industries associated with agriculture. Using the interregional CGE model, we carried out scenario setting of a global warming simulation without adaptation technology. As a result, we found that climate change caused by global warming has different influences on the region, and it turns out that a regional economic gap is generated. In Hokkaido and Tohoku, production of rice due to global warming plays a positive role.

International prices of cereals in 2018 remain high relative to the level of 2005. This paper examines the influence of the increase in international cereal prices on Hokkaido and Tofuken agriculture, based on an inter-regional computable general equilibrium model. The primary outcome of the simulation is as follows. First, an increase in international prices increases agricultural output and farm labor input in Hokkaido and Tofuken. Second, the level of real GRP decreases in Hokkaido and Tofuken. Third, the welfare level of consumers in Hokkaido improves, but that in Tofuken deteriorates.

The objective of this study is to analyze consumer heterogeneity in yogurt demand. We estimated a hierarchical Bayesian tobit model using scanner panel data. Additionally, we regressed the individual parameters obtained from the model to demographic attributes to capture the relationship between consumers' behavior toward yogurt and demographic attributes of households. The main results are as follows : first, the variance of each parameter in the hierarchical Bayesian model is large so the consumers' preference is heterogeneous. Second, consumers are aggressive in yogurt consumption. Third, the rising of consumers' age, existence of babies and increase in household income might increase yogurt demand.

This paper analyzes an impact of specialization in farming and non-farm employment on farm household food consumption in Vietnam by using data from Vietnam Household Living Standard Survey 2012. To mitigate self-selection bias due to unobserved factors affecting both non-farm employment decision and food consumption such as farmers' ability, we employ endogenous switching regression. We find that the effect of specialization in farm activity and participation in non-farm activity differ from region to region. The results suggest that not only enrolling in a non-farm sector but also specializing in farming increase Vietnamese farmers' welfare in some regions.

The impact of a natural disaster is not only from its damages to resources but the recovery project such as land consolidation also disconnects the farming situation from the previous forecast. Planning based on the current situation is hence required in order to revitalize regional agriculture. We conducted a survey of farm managers and applied a mathematical programing model in a municipality where large-plot field consolidation has been executed after the tsunami disaster. Our result shows both the number of farms and machines can be redundant because of the field improvement although few farm managers consider turning to diversified activities other than rice farming.
