aWe conducted a nation-wide questionnaire survey in 2019 and obtained valid answers from 1,094 respondents aged between 18 and 69 who were extracted using stratified two-stage random sampling. From analyses of the data, it was found that: (1) some kind of Internet uses reinforced selective exposure of information based on individual political predispositions, however the effect size was very small, (2) political polarization effects were probably not issue-based but affection-based, and so on. According to analyses of web-based panel surveys conducted annually from 2017 to 2019, the results showed that: (3) uses of some social media partially encouraged general trust in others and tolerance for different opinions (which can improve democratic process of public opinion formation), (4) uses of the political right news sites had a reciprocal causal relation with positive attitudes toward revising Article 9 of the Constitution.

As a result of analysis using survey data at three-time points in 2009, 2013, and 2017, we find that the types and structures of nationalism were shown to differ to some extent between 2009 under the Democratic Party administration and 2013/17 under the LDP / Abe administration. Since the Senkaku (Diaoyutai) and the Takeshima (Dokdo) islands disputes have been highlighted, the Japanese style retrospective patriotism is strongly associated with anti-Chinese and anti-Korean attitude. In addition, as for the type of nationalism, a type of nationalism characterized by anti-China and anti-Korean sentiments was emerged after the 2013 data, so the relationship between geopolitical conflicts and nationalism has been clarified in recent Japanese social circumstances.

The aims of this research project are to update occupational prestige scores and to construct a new scale of social status by using data of the 2016 Social Status Survey. The main findings are as follows: (1) There are considerably high correlations in the occupational hierarchy by subsamples, (2) The robustness and reliability of the occupational prestige scores are reinforced, (3) Some occupational prestige scores with gender, employment status or company size were different from original occupational prestige scores. The construction of new scale (multi-dimensional social status scale) for prestige and socioeconomic status is urgent matter.

After Lehman's fall in 2008, the number of Brazilians who stay in Japan has declined gradually. However, images of brazil and attitudes toward Brazilians by Japanese people have not necessarily been improved.
Anti-foreign attitudes for Brazilians are related to evaluation of residential area and frequency of interacting with neighbors. These results suggest that Social inclusion of not only foreign residents but also Japanese residents for local community are important to improve attitudes toward Brazilians and other foreign residents.

In this study, we have investigated the changes of Japanese nationalism from 2009 to 2013. For that purpose, we analyzed two survey data sets which were collected in 2009 and 2013 all over Japan. The result shows that Japanese patriotism doesn't change a lot and purism tends to intensify a little. However, xenophobic attitudes can be divided into two types; xenophobia towards general foreigners and towards Chinese and South Korean. The attitudes towards Chinese and South Korean became stronger in 2013, and it is more affected by patriotism than in 2009. Between 2009 and 2013, Japan has experienced terrible diplomatic problems like Senkaku/Diaoyutai Islands dispute against China. It shows that national level conflicts can affect attitudes toward opponent nationals through some kind of nationalism.

Based on the National/International standard of occupation/industry code (SSM/ISCO/ISIC), the system can assign three candidate codes to an answer of an open-ended question in a social survey. And a three-grade confidence level was assigned to the first-ranked predicted code by using classification scores. Many functions are implemented in this system, for example, an ISCO/ISIC code can be assigned to the SSM code automatically, also maintenance function contained. This system is now released to the public. Researcher can use it through the official website of CSRDA.
A new automatic coding system for social surveys is in development, which contains an open-ended question.

The aim of this research is to investigate a mechanism forming perceptions that immigrants threaten native citizens. Especially, it focuses on an influence of the media. I conducted public opinion survey while I conducted the analysis of framing of "foreigners" in newspapers which are most broadly read in the areas where respondents of the public opinion survey live. I combined these two data and analyzed the impact of the framing of "foreigners" of a newspaper on threat perceptions of citizens living in the area where it is widely read. As a result, I found that levels of threat perceptions differ according to the framing of "foreigners" in each city. If a newspaper emphasizes economic positive impacts of inflow of foreigners, people are less likely to perceive threats caused by foreigners. However, the impacts do not differ according to whether one actually reads that newspaper, which suggests social positions of foreigners in each area, not the media, affects threat perceptions.

This study conducted a panel survey of Japanese young people for an extended period of time. It focused on the following diverse aspects of the young people’s lives: social background, educational attainment, early career trajectory, family formation, and attitudes and values. By adopting the theoretical framework of “accumulation of advantages and disadvantages,” the study examines the process through which social inequality is produced and reproduced across the life course and contributes to bridging the life course research and the study of social stratification.

This study investigates the exclusionary attitudes toward foreigners. To clarify the determinants of the xenophobic attitudes, we compare Japanese attitudes toward four different immigrant groups: Korean, Chinese, South American and American immigrants. The result shows that historically constructed group positions are the most important factor affecting exclusionary attitudes toward foreigners. This study also explores a relationship between xenophobic attitudes and political consciousness. By analyzing international comparative survey data, someone who has strong xenophobic attitude is inclined to be non-partisan in the country where there is no strong far-right party. On the other hand, the pattern is not shown in the country where the far-right party has its presence in the national parliament.

When we collect occupation data by open-ended questions in social surveys, we need to categorize those data for statistics processing. Conducting the occupation coding manually is time-consuming and complicated. Therefore, we have developed a Web-basedautomatic occupation coding system for both Japanese standard categories and international standard categories with Natural Language Processing and Machine Learning.When researchers upload an occupation data file on a website, they can obtain desired occupation codes files with confidence. The system can also be applied to industry data.

This research shows the factors of anti-foreigner sentiment by analyzing individual level variables and regional level variables simultaneously. As individual level variables, contact experiences weaken the negative attitudes toward foreigners generally. But, someone who claims the purity of "Japanese" is inclined to have strong anti-foreigner sentiment. As regional level variables, the high residence ratio of Chinese and South American countries' people have negative effect on the opinion to the increase in foreign residents. On the contrary, regional residence ratio of Korean people has n...
