私の研究は、スポーツ、フィットネス、身体文化を対象に、身体がメディア、科学技術、ジェンダー、ナショナリズムと結びつきながら、どのように社会的意味を帯びるのかを社会学的に分析するものである。博士論文では、戦後日本における「八頭身」とボディビルを手がかりに、身体美文化を通じた主体化の過程を検討した。

近年は、フィットネス雑誌、SNS、ウェアラブル端末、アプリ、遺伝子検査、月経周期管理アプリなどに対象を広げ、身体が数値化・可視化・共有・評価される現代的状況を、スポーツ社会学、ジェンダー研究、メディア研究の交差点から考察している。とくに、フィットネスにおける自己最適化、スポーツ科学知のメディア化、フェムテックやスポーツゲノム科学がもたらす身体政治に関心をもつ。

現在、青土社より『フィットネスの時代:最適化する自己と社会』(2026年8月予定)、青弓社より『八頭身とボディビルの社会史:戦後日本における身体美文化の系譜』(2027年1月予定)を、それぞれ単著として刊行予定である。前者は現代のフィットネス文化と自己最適化を、後者は戦後日本の身体美文化の系譜を対象とする研究成果である。

  • Genealogical study of female physical beauty culture in postwar Japan, focusing on the appearance of hattoushin as "excited body" and "cosmetic gymnastics"

    Hattoushin (a 1:8 head:body length ratio) represents a distinctive way of defining female physical beauty. Discourse on this topic in Japan appeared during the postwar reconstruction period, sometimes referred to as "the age of the physical body," as a representation of the ideal female physical image, and it continues to resonate with Japanese women today.<br> This paper takes up the notion of hattoushin and addresses the following issues using Butler's genealogical method for gender: ① What were the social contexts in which it emerged, and ② what techniques of body modification did it generate? ③ With a particular focus on female PE, in which the pursuit of physical beauty was incorporated, the position of PE as an essential element for femininity is explored. The aim of the present paper is to clarify how females and/or femininity were defined in terms of physical traits.<br> The results are as follows.<br> ① The emergence of hattoushin was due to the appearance and rise of fashion modeling as a profession, and ofMs. Kinuko Ito winning third place in the Miss Universe contest. However, the popularity of hattoushin was not merely because it came to be used as a description of the body. It was recognized as a well-developed "health andbeauty" movement that could overcome the negative aspects of defeat/occupation and was regarded as a symbol of postwar female liberation.<br> ② As a result of this rising attention to the female body form, hattoushin was recognized as the ideal that could be achieved through new techniques such as cosmetic gymnastics and "physical standard values" for visualizing ideal physical beauty.<br> ③ Postwar female PE reform had a particularly strong influence on the development of female physical beautyculture, aiming to establish the independence of females under the slogan "Female PE with female hands". Inthat process, the pursuit of physical beauty through cosmetic gymnastics took a central role. Female PE reformdeveloped because postwar feminism itself evaluated the pursuit of physical beauty as a medium for subjectiveself-expression by women who were liberated.<br> This process is similar to Butler's statement "The feminist subject turns out to be discursively constituted by the very political system that is supposed to facilitate its emancipation". That is, female PE itself, which is a feminist political system promoting female liberation, decided on an ideal form of femininity, and thus strengthened "female" categorization. More specifically, feminism itself called for the pursuit of physical beauty, and inspired many women.

  • Construction and fluctuating views of the male body::Focusing on formation processes of the "male beauty/body (bodybuilding) culture"

    In postwar Japan, the United States (US) could be viewed as Japan's "significant other." The US had a considerable cultural impact on Japan and was responsible for alterations in postwar Japanese identity. Of particular importance was the influence of the US on the popular view of body form. The postwar restructuring of Japan's national identity included the adoption of new views of the body as a result of US influence. This study investigated the culture of male beauty/body (bodybuilding) that emerged in Japan during the postwar period of occupation, and revealed how "male beauty" consciousness was generated in relation to nationalism by focusing on (1) the social context in which "male beauty/body culture" emerged and (2) the changes in conceptions of masculinity and body consciousness. This analysis yielded the following results:<br> (1) Bodybuilding emerged in the social context of the occupation/reconstruction period and from a masculine crisis of male feminization in Japan. It was developed by the Japan Bodybuilding Association (JBA) as part of a movement to create "new Japanese men".<br> (2) However, bodybuilding was criticized as being feminine, linked to homosexuality, and leading to a useless "Hercules-type" body.<br> (3) In response to this criticism, the JBA shifted its aim from the acquisition of a burly, Herculean build to one of a healthy and functional ("Hermes-type") body that represented harmony between the body and the spirit. The aim of this shift was to gain legitimacy for bodybuilding as a masculine act.<br> In addition to these aims in trying to help create "new Japanese men", the JBA also intended to legitimize male bodybuilding culture within a national context, seeking to popularize and expand its activity by criticizing the American "Hercules-type" body while promoting the "Hermes-type" body preferred in Japan. In this way, discourse concerning the legitimacy of male beauty/body (bodybuilding) culture developed in conjunction with nationalism, and created an important forum for consideration of the ideal Japanese male body form.

  • The Ageing Body and Bodily Practices in Elderly Males:A Case Study of Bodybuilders in Tokyo's Gym S

    As Japan's rapidly ageing society continues to expand, bodily practices targeting the ageing body, such as sports facilities for the elderly and anti-ageing goods, have become ubiquitous. Previous studies have shown that such practices are of value to the elderly, enabling them to improve their quality of life and to redefine their identity. However, these studies have not fully explained why the elderly desire such values and how they acquire them.<br> Recognizing the problematic nature of this lack of deeper understanding, this paper examines the case of elderly male bodybuilders at Tokyo's Gym S, focusing on their practices to reveal how they derive value from their bodybuilding. The research finds that elderly bodybuilders do not view their bodily practices as a solution to physical ageing. Rather, they derive value from being different from those they view as "the ordinary elderly," those members of Gym S who work out in order to promote good health. The elderly male bodybuilders distinguish themselves from "the ordinary elderly" by seeking new images of their bodies and through acceptance of their ageing.<br> In conclusion, this paper argues that the bodily practices of bodybuilding among the elderly could possibly promote ageing as "abnormal," while they could also elevate the body image of the elderly in spite of the body's natural ageing process. This paper points out the necessity of examining how the ageing body and bodily practices are connected through investigations of the lived experiences of the elderly.
