This study investigates the factors affecting financial literacy in Japan using data from Osaka University's Preference Parameter Study. We examine several demographic, socio-economic, and psychological variables drawn from the social learning, consumer socialization, and psychological theories of learning. The results indicate that the demographic factors of gender, age, and education; the socio-economic factors of income and occupation; and the psychological factor of perceptions of the future significantly affect the level of financial literacy. The results are robust to different measures of financial literacy and emphasize that social contact and people's future orientation can improve financial literacy levels in Japan.

Success in the current complex and sophisticated financial marketplaces depends on the ability of people to make sustainable financial decisions to improve their future well-being, for which financial literacy is a pathway. This study examines the relationship between the demographic and socio-economic factors and financial literacy in Japan by segregating financial literacy into financial knowledge, attitude, and behavior, and providing a deeper understanding of the relationships. The methodology included using data from the Financial Literacy Survey 2016 by the Central Council for Financial Services Information of Japan. We used a linear regression model to explain how demographic and socio-economic factors relate to financial knowledge, attitude, and behavior. Results show that education, the balance of financial assets, and the use of financial information are positively related, while the experience of financial trouble is negatively related to financial knowledge, attitude, and behavior. We show that males are more financially knowledgeable than females, but females are more positive than males with regard to financial behavior and financial attitude. Age is positively related to financial knowledge but negatively related to financial attitude, thus suggesting that middle-aged people in Japan are more financially knowledgeable, but younger and older people are more positive with regard to financial behavior and attitude. The findings have implications for policymakers.

This study examines the role of financial literacy in reducing anxiety about life in old age. We hypothesize that financial literacy increases preparedness for old age through better savings and investment decisions, leading to the accumulation of more assets and earning more income, which enhances financial capacity and reduces anxiety. Using data from a nationwide panel survey in Japan, we provide evidence that financial literacy can reduce anxiety about life in old age by making people capable of accumulating more assets and earning more income. Moreover, the interaction of financial literacy with age and spouse reduces anxiety, while living with children increases anxiety about life during old age. We check the robustness of our results using an alternative measure of financial literacy, changing composition of the sample, controlling for residents’ geographical dispersion, and testing for endogeneity bias. The major findings remain unchanged after considering these factors.

The worldwide COVID-19 vaccination program is already underway, raising hopes and aspirations to contain the spread of the COVID-19 pandemic that halted economic and social activities. However, the issue of vaccine effectiveness and its side-effects is influencing the potential acceptance of vaccines. In this uncertain situation, we used data from a nationwide survey in Japan during February 2021, following the Japanese government’s initial phase of COVID-19 vaccination. Our results show that 47% of the respondents are willing to take a vaccine once it is available, while 22% are not willing and another 31% remain indecisive. Our ordered probit regression results show that demographic, socioeconomic, and behavioral variables such as gender, age, subjective health status, children, household income, household assets, financial literacy, future anxiety, and myopic view of the future are associated with willingness to take a COVID-19 vaccine. Our findings suggest that Japan’s government should not adopt a one-size-fits-all policy to promote the vaccination program, but rather target people with specific socioeconomic backgrounds who are less willing and more hesitant to take a vaccine.

According to a survey by Japan’s Ministry of Health, Labor, and Welfare in 2017, 3.6% of Japanese adults—equivalent to about 3.2 million people—have suffered from problem gambling at some point in their lifetime. This study examines the relationship between financial literacy, financial education, and gambling behavior (measured as gambling frequency) among the Japanese population. We hypothesize that financially literate and financially educated people who use their knowledge to make sound financial decisions are less likely to gamble. The data used in this study are from a nationwide survey in Japan from the Preference Parameters Study of Osaka University in 2010 (n = 3687). To control for endogeneity bias between financial literacy and gambling behavior, we use the education of respondents’ fathers as an instrumental variable. The results from the probit-instrumental variable model show that financial literacy has a significantly negative relationship with gambling frequency, while financial education has no significant relationship with gambling frequency. Our findings suggest that problem gambling may be mitigated by promoting financial literacy, but no such conclusion can be drawn for financial education.
