In 1989 a woman editor at a Fukuoka publishing house, forced out after a manager spread sexual rumours about her inside and outside the firm, brought what became Japan’s first “sexual harassment” lawsuit. On 16 April 1992 the Fukuoka District Court found the perpetrator’s tort liability and the company’s employer liability, ordering 1.65 million yen in damages. The long loanword “sexual harassment” entered wide circulation through the press coverage and became a buzzword of the year. Japanese society had begun to recognise workplace sexual conduct as a legal problem.

Sexual harassment (Japanese sekuhara) is sexual conduct in the workplace that harms another worker’s conditions or environment. In Japan the Equal Employment Opportunity Act, Article 11, imposes a prevention-measure duty on employers, organised into the quid pro quo and hostile-environment types. This article covers the concept’s history, the Japanese legal framework, the leading cases, and international comparison.

Concept history

The concept formed in the 1970s US. The legal scholar Catharine A. MacKinnon, in Sexual Harassment of Working Women (1979), framed sexual conduct as a form of sex discrimination falling within Title VII of the 1964 Civil Rights Act. The US Supreme Court, in Meritor Savings Bank v. Vinson (1986), recognised the “hostile work environment” type as a Title VII violation, fixing the two types internationally: quid pro quo (demanding sexual relations in exchange for promotion or hiring) and hostile environment (sexual conduct harming the work environment).

The concept reached Japan in the late 1980s. The 1989 Fukuoka case was the first lawsuit on it, and the April 1992 ruling, finding workplace sexual conduct a tort, was a landmark; the term won the new-words-and-buzzwords prize that year.

The Japanese legal framework

The Equal Employment Opportunity Act (enacted 1985, in force 1986) initially had no harassment provision. The 1997 amendment (in force 1999) added a “consideration duty” on employers, raised to a “measure duty” in the 2006 amendment (in force 2007). Article 11(1) now requires employers to take necessary employment-management measures, including a consultation system and appropriate response, to prevent disadvantage to workers’ conditions (quid pro quo) and harm to the work environment (hostile environment) from sexual conduct. Breach draws ministerial advice, guidance, and recommendation, with public naming of firms that ignore a recommendation (Article 33).

The administrative guideline (MHLW Notice 615 of 2006) sets the two types: quid pro quo, where a worker suffers dismissal, demotion, or pay cut for responding to (refusing or protesting) sexual conduct; and hostile environment, where sexual conduct harms the work environment and seriously impairs the worker’s performance. The typology is for convenience; cases often overlap. The 2019 amendment (in force June 2020, April 2022 for SMEs) strengthened the consultation-system duty, banned disadvantageous treatment for consulting (Article 11(2)), and added effort duties toward other firms’ workers and protection of job applicants.

Leading cases

The 1992 Fukuoka case (16 April 1992) found the perpetrator’s tort and the company’s employer liability and ordered 1.65 million yen, holding sexual conduct that injures a woman worker’s personality and worsens her work environment unlawful, the theoretical base for later case law and guidelines. In April 2018 a Ministry of Finance administrative vice-minister was reported to have made continued sexual remarks to a woman journalist; he resigned after recordings emerged, and the ministry was found liable to a pay-cut-equivalent sanction, a case of harassment by an elite figure in a high office. In August 2018 Tokyo Medical University was reported to have systematically deducted points from women and re-sitting applicants, a discrimination case (suppressing women doctors over career interruption from pregnancy and childbirth) showing the structural link between women’s working conditions and harassment.

The #MeToo movement, triggered by the October 2017 Harvey Weinstein case, spread denunciations worldwide; in Japan, the 2017–2018 civil litigation by the journalist Ito Shiori and disclosures across publishing, sport, and politics renewed attention. Ito’s civil suit (Tokyo District Court win 2019, finalised at the High Court and Supreme Court 2020–2022) and the Finance Ministry case kept the criminal and civil handling of harassment by high-status figures a continuing issue.

International comparison

In the US, Title VII is the principal federal basis, enforced by the EEOC, with the quid pro quo and hostile-environment types established and damages, including punitive damages, larger than in Japan. The EU Equal Treatment Directive (2002/73/EC, later 2006/54/EC) obliged member states to legislate against harassment, embedding employer prevention and consultation duties. The ILO adopted the Violence and Harassment Convention (No. 190) in June 2019, requiring prevention, remedy, and responsibility; Japan had not ratified it as of 2025, with domestic legislation toward ratification under discussion.

Related concepts

Disadvantageous treatment or harassment over pregnancy, childbirth, or childcare leave (“matahara”) is regulated under Article 9 and the childcare-leave law; workplace harassment based on a superior relationship (“pawahara”) draws an employer measure duty under the labour-policy act (in force June 2020), and pawahara with a sexual element can overlap with sexual harassment. Since #MeToo, attention has risen to power-structural harassment in entertainment, sport, and culture.
