  • Japan: Political Developments and Data in 2024:New PM Ishiba Forms Minority Government following Electoral Defeat

    Airo Hino, Hiroki Ogawa, Robert A. Fahey, Ling Liu

    European Journal of Political Research Political Data Yearbook   64 ( 1 ) 363 - 385  2025.12  [Refereed]

    　View Summary

    Abstract

    Following several years of opinion polling decline, Japan's ruling Liberal Democratic Party (LDP) sought to draw a line under successive scandals with the election of a new leader, Shigeru Ishiba. However, the LDP-led coalition went on to lose its majority in the lower house for the first time since 2012 in the snap election that Ishiba immediately called, leaving him at the head of a minority government. The ruling party also faced internal divisions over his decision to exclude members implicated in scandals from candidate lists in the election. The Democratic Party for the People, formerly a rump party left over following mergers among mainstream opposition groupings, surged in this election, gaining significant attention for party leader Yuichiro Tamaki, while new far-right parties also made minor gains in the lower house for the first time.

  • Is Partisan Selective Exposure an American Peculiarity? A Comparative Study of News Browsing Behaviors in the United States, Japan, and Hong Kong

    Tetsuro Kobayashi, Zhifan Zhang, Ling Liu

    Communication Research (online first)    2024.10  [Refereed]

    　View Summary

    While partisan selective exposure has been robustly observed in controlled settings, its cross-national differences have been understudied. Many earlier studies were conducted in the United States (US); however, partisan selective exposure is weak outside the US. This study measured browsing behavior using comparable mock news sites in the US, Japan, and Hong Kong to probe the antecedents of cross-national differences in partisan selective exposure. Two observational studies showed that partisan selective exposure is robustly detected in the US but weak or almost absent in Hong Kong and Japan, and that affective polarization toward political out-groups partially explains the cross-national differences observed between the US and Japan, as well as between Hong Kong and Japan. Perceived media credibility and dialectical self did not explain cross-national differences. The universality of partisan selective exposure and its mechanisms are discussed.

  • Japan: Political Developments and Data in 2023: Financial Scandals Hasten the Ruling Party's Polling Decline

    AIRO HINO, HIROKI OGAWA, ROBERT A. FAHEY, LING LIU

    European Journal of Political Research Political Data Yearbook   63 ( 1 ) 260 - 274  2024.07

    　View Summary

    Abstract

    Japan's ruling Liberal Democratic Party (LDP) continued to slide in public opinion polls in 2023, with Prime Minister Fumio Kishida's approval ratings never recovering from the scandal over the party's association with the controversial Unification Church that was exposed in the previous year. Kishida survived an assassination attempt in April, and the LDP's subsequent strong performance in by‐elections helped to temporarily stabilise his leadership. However, the party faced a fresh scandal in November, when a police investigation into the misreporting and mishandling of ‘slush fund’ money by the LDP's major factions led to the removal of four senior Cabinet ministers and an even sharper decline in support for the Kishida administration. Rising consumer prices, due in part to a weakening of the Yen, were also a major concern throughout 2023, with inflation for the full year reaching 3.1 per cent, its highest level since 1981.

    　View Summary

    Abstract

    The assassination of former Prime Minister Shinzō Abe in July had an enormous impact on politics in Japan in 2022, with subsequent recriminations regarding connections between ruling party lawmakers and the controversial Unification Church new religious movement leading to public outcry and forcing Prime Minister Kishida to remove several high‐profile Ministers from his Cabinet. There was contentious debate over whether a state funeral should be held for Abe, and a new law was passed restricting the fundraising activities of religious groups like the Unification Church. Meanwhile, Japan continued to slowly roll back restrictions introduced to combat COVID‐19, finally reopening its borders in October. The Russian invasion of Ukraine provoked protest from the Japanese government and contributed, along with a major drop in the value of the yen to the US dollar, to rising consumer prices, with inflation reaching a 42‐year high in October.

    　View Summary

    We empirically compared Computer-Assisted Self-administered Interview (CASI) based on deliberation within himself/herself with Mini-Publics (MP) based on deliberation with other people, CASI is preferable because it guarantees representativeness of sample better and costs less. However, this research project also found that deliberation within himself/herself was not as effective as deliberation with other people in some aspects of attitudes. For example, when a respondent wrongly believed incorrect information to be true, only deliberation with other people can correct his/her wrong concept. Therefore, we now know that each of CASI and MP has its own merit, and it would be premature to conclude that one method is better than the other.

    This project investigates how individuals’ perceptions of media—particularly hostile media perception (HMP) and general media trust—shape their selective exposure to political information. While a growing body of literature has documented people’s tendency to avoid attitude-discrepant content, most of this research is situated within the U.S. context, where trust in the media is exceptionally low. This project addresses the question of whether such patterns hold in other cultural and media environments, and whether HMP plays an independent role beyond general distrust.Over the past year, I developed a typology of media trusters based on both trust levels and perceptions of hostility in political news environments. I conducted a pilot survey in two national contexts, Japan and the United States, which differ markedly in their levels of media trust. The results suggest that HMP is a distinct construct from low media trust and has a stronger predictive power in explaining selective exposure behaviors. Respondents with strong hostile media perceptions are more likely to selectively engage with ideologically congenial content.In the next phase, I plan to expand the cross-national design to include a wider sample of countries with varying levels of media trust, using embedded experiments. This will allow for more robust tests of how HMP operates across different media systems and political cultures.

    To promote deliberative democracy, it is crucial to understand how voters respond to information that appears to threaten their existing political beliefs. Research has convincingly demonstrated the propensity of individuals to avoid exposure to attitude-discrepant content. However, such research is overwhelmingly based on the U.S. context, where trust in the media is at a near-global low, suggesting that findings may not be generalizable to other national contexts.During this project, I focused on advancing the theoretical foundations for analyzing the effects of national media trust levels on the dynamics of responses to information that conflicts with individuals’ political attitudes. This was accomplished by conducting a thorough and critical literature review, which strengthened the overall theoretical framework of the project. It yielded two major deliverables. The first is a review slated for publication in the Encyclopedia of Political Communication, edited by Alessandro Nai and Dominique Wirz of the University of Amsterdam, Netherlands, and Max Groemping of Griffith University, Australia. The second is a collaborative paper with Tetsuro Kobayashi of Waseda University and Zhifan Zhang of George Washington University, USA. This paper features an extensive theoretical discussion on the influence of media trust and the related concept of media-party parallelism on the selective exposure of political information that either aligns with or contradicts one’s own political stance.

  • 非アメリカコンテクストにおける有権者の政治情報に対する選択的接触傾向の探索

    2021  

    　View Summary

    本課題は、メディア信頼が高い国における有権者は、なぜメディアを信頼するにもかかわらずメディアの報道に影響されずに政治的意見を変えないのかという問いを解明することを目的にしている。メディアがどのような効果を持つかという問いは、政治コミュニケーション分野の古典的な命題であり、今日においても重要な意味を持つ。この問いに対して蓄積されてきた主だった学術的知見は、メディアが人々に与える影響は「限定的なものである」というものであり、いわゆる「限定効果論」として定式化される。この理論は、アメリカをはじめ、日本や欧州諸国など多くの国の実証データによって支持されている。しかし、メディア効果が限定的であるという実証結果を説明するために用いられる既存の理論は、主にアメリカで発展したものであり、必ずしもそのまま他の国に適用できるわけではないと考えられる。なぜなら、アメリカは他国よりもメディアに対して不信感が強いためである。本課題は、人の態度維持の鍵となる情報接触過程に着目し、より高いメディア信頼を有している国の人は果たして既存の理論が想定する（意見と相容れない報道への）接触回避を行うのかを検証した。具体的には、調査実験（survey experiment）という手法を用いて、メディアの信頼度が国際的に高いレベルにある日本、中間レベルにあるドイツと香港を、アメリカと比較した。その結果、アメリカ人は既存理論の想定通りに自らの意見と相容れないメディア報道への接触を避けるものの、より高いメディア信頼を有している日本人、ドイツ人と香港人は、自らの意見と相容れない報道への接触回避をしないことを明らかにした。成果として、自分の博士論文にまとめ、2021年9月に早稲田大学政治学研究科に提出した。この博士論文は、2021年度政治学研究科長賞に受賞した。

  • 有権者が政治意識を持続する仕組みの解明：メディアの信頼度を軸とした国際比較

    2020  

    　View Summary

    これまでの研究ではメディアの政治的効果が限定的であると言われてきたが、なぜ人々の政治意識はメディアに影響されないのか。既存の理論は、主にメディアへの不信感が強いアメリカの文脈で発展したものであり、メディアの信頼度が高い国々にそのまま適用することには問題がある。このような問題意識を踏まえて、本研究は、メディアの信頼度が世界で高いレベルにある日本、ならびに中間レベルにある香港を、アメリカと比較することを通し、 高メディア信頼国で有権者はいかに政治意識を持続しているかのメカニズムを解明することを目的としていた。研究手法としては、オンライン調査実験（Survey Experiment）を行う。本課題では、調査実験を実施するための事前準備を行った。成果の一部が、学会報告論文にまとめて、International Communication Association Annual Conference及び日本選挙学会にて報告される予定である（報告採択済み）。

  • 政治情報に対する選択的接触傾向の日米比較

    2019  

    　View Summary

    有権者はメディアの政治報道に接する際に、自らの意見と一貫する情報を積極的に接触し、相容れない内容を避けるという傾向があると言われる。この傾向は「政治的選択的接触」（Political Selective Exposure）とも呼ばれ、そのことへの懸念が昨今のポスト真実の伝播と言われる状況を踏まえて、特に高まっている。本研究では、日本とアメリカにおける政治的選択的接触の傾向に違いがあるのかを解明することを目的としていた。研究手法としては、オンライン調査実験（Survey Experiment）を行う。本課題では、調査実験を実施するための事前調査を行った。成果の一部が、3rd WASEDA BRUSSELS CONFERENCEにて報告された。
