What shapes preferences for income redistribution? Studies find that social identification plays an important role. In this paper, I argue that in-group favoritism generated through income proximity and out-group discrimination stemming from a nation/foreigner cleavage affect redistribution preference. Using data from a survey experiment with 4,002 Japanese citizens, I examined whether priming the poor as recipients of public assistance (or Seikatsu Hogo) generates more (less) support for income redistribution among the poor (the wealthier) and whether priming foreigners as public assistance recipients decreases support for redistribution. Analyses reveal that respondents with annual household income of 5–10 million yen negatively respond to the treatment priming the poor as public assistance recipients. Results also indicate that priming foreigners as public assistance recipients decreases support for redistribution. These findings corroborate previous research that finds evidence from North America and Europe. Analyzing a sample from Japan offers the external validity because the recent rise in income disparity in Japan involves unique characteristics including pauperization of low-income groups without enriching the wealthy. A rapid increase in the inflow of immigrants to Japan necessitates the need to study how Japanese people shape their redistribution preference in response to a growing number of foreign residents.

Does the Japanese public consider shared ancestry the most essential condition for inclusion of an individual as a member of their country's citizenry? This paper empirically assesses how the public in the ethnic nation views citizenship acquisition criteria. The originally conducted survey based on a conjoint format in Japan (2015) displays interesting results. Overall, Japanese people most heavily rely on the nationalities of parents in judging who qualifies as 'Japanese', confirming the contentions of previous works that highlight Japanese people's belief in a mono-ethnic Japan. More detailed statistical analyses further reveal that Japanese people consider ethnic heritage through the father as the most essential criterion while the mother's nationality and country of upbringing are also relevant. These results seem to reflect Japan's long-lasting beliefs in cultural homogeneity as well as patriarchal values, which are reinforced by a patrilineal tradition of citizenship. This research advances the discussion on how to classify citizenship features by disaggregating ethnic lineage into paternal and maternal lines. Furthermore, it suggests a reevaluation of Japan's institutional and social attachment to patrilineal ethnic heritage in order to ease multiple layers of discrimination posed against (particularly female) migrants and to realize a sound multiethnic society.

This article re-examines Japan's entry into international society, focusing on leading Japanese diplomats. It has been believed that Meiji leaders' interpretation of international society and diplomacy was characterized by power-political and zero-sum thinking, and they took a realistic approach in an imperialistic system. However, the present article demonstrates that Japanese diplomacy in and after the 1890s was basically guided by interest-oriented and non–zero-sum thinking which was closely tied to the international order. Leading Japanese diplomats, who learned from their experiences in diplomacy with Western countries, understood the significance of norms as well as the importance of military power, and pursued Japan's national interests within the rules and norms of international society. These findings offer a new image of the principles of modern Japanese diplomacy, the mechanisms of Japanese imperial expansion, and the process of the spread of norms in international society.

Guth's exhaustive analysis of craft culture in Edo period Japan is required reading not just for anyone who seeks to better understand the world of craft, but also the vibrant world of early modern Japan in general. She also notes that there were, broadly speaking, two categories of craft: one was craft produced for the burgeoning early modern urban elite, often by celebrity craftspeople, and the other produced in the rural areas of Japan and intended mainly for local use, a distinction that Guth calls "art craft" versus "folk craft". Graph Christine Guth's monograph offers a new perspective on craft culture in early modern Japan. [Extracted from the article]

Background: Tobacco price increase is an effective measure to reduce tobacco smoking. In Japan, the price of combustible cigarettes increased in 2018 and 2020, and that of heated tobacco products increased every year from 2018 to 2020 by tobacco excise taxation. Also, the general consumption tax increase in 2019 slightly raised the retail prices of tobacco products. We investigated the impact of this stepwise tobacco price increase on combustible cigarette smoking status among Japanese adults.Methods: Five waves of annual longitudinal data (2017-2021) from The Japan "Society and New Tobacco" Internet Survey (JASTIS) (31,930 observations of 11,896 individuals) were analyzed. Multivariable logistic regression with generalized estimating equation was fitted, adjusting for the prefecture of residence, age, sex, socioeconomic status, health status, alcohol drinking, former smoker's duration of smoking cessation, and the current smoker's number of cigarettes smoked per day.Results: The 2018 price increase was associated with a reduction in relapse (adjusted odds ratio [aOR] 0.54, 95% confidence interval [CI] 0.42 to 0.68) and an increment in cessation (aOR 1.20, 95% CI 1.02 to 1.42). The price increase in 2019 was not associated with relapse (aOR 0.84, 95% CI 0.63 to 1.10) or cessation (aOR 0.95, 95% CI 0.80 to 1.13). The 2020 price increase was associated with a reduction in relapse (aOR 0.59, 95% CI 0.42 to 0.81) and an increment in cessation (aOR 1.45, 95% CI to 1.21, 1.73).Conclusion: The price increase caused by tobacco excise taxation was associated with a reduction in combustible cigarette smoking.

Characterizing the detailed spatial and temporal dynamics of plant pathogens can provide valuable information for crop protection strategies. However, the epidemiological characteristics and evolutionary trajectories of pathogens can differ markedly from one country to another. The most widespread and important virus of brassica vegetables, turnip mosaic virus (TuMV), causes serious plant diseases in Japan. We collected 317 isolates of TuMV from Raphanus and Brassica plants throughout Japan over nearly five decades. Genomic sequences from these isolates were combined with published sequences. We identified a total of eighty-eight independent recombination events in Japanese TuMV genomes and found eighty-two recombination-type patterns in Japan. We assessed the evolution of TuMV through space and time using whole and partial genome sequences of both nonrecombinants and recombinants. Our results suggest that TuMV was introduced into Japan after the country emerged from its isolationist policy (1639–1854) in the Edo period and then dispersed to other parts of Japan in the 20th century. The results of our analyses reveal the complex structure of the TuMV population in Japan and emphasize the importance of identifying recombination events in the genome. Our study also provides an example of surveying the epidemiology of a virus that is highly recombinogenic. [ABSTRACT FROM AUTHOR]

While most existing research attributes contemporary Japanese emigration to the pursuit of a better lifestyle, recent qualitative studies point out that concern about country risks is a significant driver . We explore Japan's brain-drain potential and factors shaping Japanese skilled workers' interest in emigrating to other countries based on our original survey with an experimental component. We first undertake descriptive analysis using respondents in the (baseline) control group and examine what types of Japanese skilled workers are interested in emigration. We then use respondents in the control and treatment groups to test our preregistered hypotheses regarding the impact of information about Japan's country risks on their attitudes. The results of our descriptive analysis show that respondents with overseas experience and younger respondents are particularly motivated to consider emigration. Another notable finding is that respondents who distrust the government and media are also more likely to consider leaving Japan than those who do not. Furthermore, through our randomized survey experiment, we find that exposure to information about long-term economic risk encourages people to consider living abroad in the future. These results suggest that the brain drain from Japan is likely to continue, pointing to a need for policy actions to tackle it. [ABSTRACT FROM AUTHOR]

Objectives: This study examined the association of presenteeism with experiences of poverty among Japanese workers during the COVID‐19 pandemic. Methods: A prospective cohort study of Japanese workers was conducted using an Internet monitoring survey. The baseline survey was conducted in December 2020, and a follow‐up survey in December 2021. Of the 27 036 workers who participated, 18 560 (68.7%) completed the follow‐up survey. The 11 081 who reported that they were not in financial difficulty in the baseline survey were included in the analysis. The degree of work functioning impairment was assessed at baseline using the Work Functioning Impairment Scale (WFun). Households' experience of not being able to pay for food and clothing was identified in the follow‐up survey. The odds ratios (ORs) of presenteeism determined by WFun associated with poverty were estimated using a multilevel logistic model. The multivariate model included age, sex, marital status, job type, income, education, smoking, alcohol consumption, number of employees in the workplace, and the incidence rate of COVID‐19 by prefecture at baseline. Results: In the multivariate model, the odds ratio of experiencing food insecurity increased with high WFun score: compared with WFun scores of 13 or less, the OR was 1.87 (95% CI: 1.43–2.43, P <.001) for WFun scores of 14 or more and 3.26 (95% CI: 2.58–4.12, P <.001) for WFun scores of 21 or more. Conclusions: In addition to labor productivity, the adverse effects of presenteeism on social security‐related concerns such as poverty require further attention. [ABSTRACT FROM AUTHOR]

Objectives: Although gender stereotypes regarding paid work and unpaid work are changing, most wives are responsible for taking care of the family and home in Japan. It is unclear how time spent on housework and childcare has changed between working men and women during the COVID‐19 pandemic in Japan. The purpose of this study is to investigate how working men and women's responsibilities for housework and childcare changed during the COVID‐19 pandemic in Japan depending on work hours, job type, the number of employees in the workplace, and frequency of telecommuting. Methods: A cross‐sectional analysis (N = 14,454) was conducted using data from an Internet monitoring study (CORoNa Work Project), which was conducted in December 2020. A multilevel logistic model with nested prefectures of residence was conducted to estimate the odds ratio (OR) for change in time devoted to housework and childcare among men and women adjusting for age, household income, presence of spouse who work, work hours, job type, the number of employees in the workplace, frequency of telecommuting, and the incidence rate of COVID‐19 by prefecture. Results: More women tended to perceive that their time of housework and/or childcare had been changed (increased housework: OR 1.92, 95% CI [1.71–2.16], P <.001; decreased workhours: 1.66 (1.25–2.19), P <.001: increased childcare: OR 1.58, 95% CI [1.29–1.92], P <.001; decreased childcare: 1.11 (0.62–2.00), P =.719). Conclusions: The time spent by women on housework and childcare changed significantly compared to men during the COVID‐19 pandemic in Japan. [ABSTRACT FROM AUTHOR]
