Japanese: Japan Employment Law Alert: 顧客等によるハラスメント(カスハラ)及び求職者等へのセクハラ対策の義務化‐対社外のハラスメント対応も義務に
Until now, companies have been required to take measures — such as establishing internal reporting channels — against harassment occurring “within the workplace” (power harassment, sexual harassment, harassment relating to pregnancy and childbirth, and harassment relating to childcare and family care; collectively, “Internal Harassment”). With effect from October 1, 2026, however, amendments to the relevant statutes1 (the “Amendments”) will require companies to also take measures against harassment arising “in dealings with parties outside the company” — namely, harassment by customers and other counterparties (commonly referred to as “customer harassment,” or kasu-hara) and sexual harassment towards jobseekers etc. and similar persons (collectively, “External Harassment”).
The Amendments were prompted in part by a 2023 survey conducted by the Ministry of Health, Labour and Welfare (the “MHLW”), which revealed the following2
Given this background, the Amendments impose on companies — regardless of size — an obligation to take the following measures in respect of External Harassment: (i) clarifying the employer’s policy, and communicating it to, and raising awareness of it among, employees; (ii) establishing reporting channels; (iii) responding promptly and appropriately after an incident; and (iv) other measures. These are largely the same as the measures already mandated for Internal Harassment.
The emphasis differs, however: measures against Internal Harassment are aimed primarily at ensuring that a company’s own employees become neither perpetrators nor victims, whereas customer-harassment measures are aimed at preventing employees from becoming victims, and measures against sexual harassment towards jobseekers etc. are aimed at preventing employees from becoming perpetrators. For the definition of each type of harassment and the details of the required measures, please refer to the MHLW’s “Pamphlet on the Harassment Measures to be Taken by Employers” (available in Japanese only).
This newsletter first reviews the definitions of customer harassment and sexual harassment towards jobseekers etc., which are the subject of the Amendments (Section 2 below), and then outlines the measures required in respect of these forms of harassment, highlighting those that warrant particular attention (Section 3 below). Finally, it touches on the legal risks of failing to take adequate measures (Section 4 below).
Customer harassment means conduct that (i) is engaged in by a customer or other counterparty, (ii) exceeds the bounds of what is socially acceptable in light of the nature of the duties performed by the employees whom the company employs and other circumstances, and (iii) thereby harms the employees’ working environment.
“Customer or other counterparty” in clause (i) above includes the company’s contractual counterparties. Customer-harassment measures are therefore not irrelevant even to companies that operate on a purely B2B basis.
As to clause (ii) above, whether a demand made by a customer or other counterparty exceeds the bounds of what is socially acceptable is assessed holistically, by reference to both the “substance of the conduct” and the “means or manner” in which it is carried out. While the assessment will be straightforward in some cases, we expect that in many cases it will be difficult to draw the line between harassment and a legitimate demand. In this regard, the MHLW gives the following examples of conduct amounting to customer harassment:
|
Conduct whose “substance” exceeds the bounds of what is socially acceptable |
Conduct whose “means or manner” exceeds the bounds of what is socially acceptable |
|
|
Sexual harassment towards jobseekers etc. means conduct of a sexual nature by an employee of the employer that obstructs the job-search activities of jobseekers etc. The definition of “sexual harassment” itself is substantially the same as for sexual harassment under the Internal Harassment rules. The class of protected persons is different, however: “jobseekers etc.” means persons who are not employees of the employer and who (i) apply for a position advertised by the employer, (ii) participate in the employer’s recruitment activities, or (iii) undertake practical training with the employer (e.g., an internship). The provision is aimed principally at sexual harassment occurring in job interviews, informational visits with alumni employees (so-called OB/OG visits), communications with company recruiters, and internships.
The measures that companies will be required to take under the Amendments are set out below (measures that have no counterpart in the Internal Harassment rules are underlined).

Of these measures, the following warrant particular attention when compared with the Internal Harassment rules.
One customer-harassment measure that warrants attention is the requirement to establish, and communicate to employees, the procedures to be followed where an employee suffers customer harassment (or conduct suspected of being customer harassment).
The Internal Harassment rules are directed at preventing employees from committing harassment, and the required measures therefore focus on identifying clearly what constitutes harassment and prohibiting it. The customer-harassment measures, by contrast, are directed at preventing employees from suffering harassment and at ensuring an appropriate response where they do; this requirement is an expression of that objective.
The “response procedures” must be tailored to the actual circumstances of the company’s workforce, but the MHLW offers the following examples. Because these examples are directed primarily at B2C customer harassment, they will not necessarily translate to the B2B context; they are nevertheless a useful guide to the level of granularity required in order to satisfy the statutory obligation.
No particular method of communication is prescribed. The MHLW’s examples include preparing and distributing a manual and holding training sessions and seminars.
Similar to the measure discussed in subsection (2) above, companies must also establish, and communicate to employees, a policy for dealing with customer harassment considered particularly egregious.
As to what is “particularly egregious,” the MHLW offers only one example — repeatedly making excessive demands of an employee — leaving the assessment far from straightforward. That said, while whether conduct amounts to customer harassment is, per the MHLW, assessed holistically by reference to the “substance of the conduct” and the “means or manner” in which it is carried out, as noted in Section 2(1) above, the categories of conduct listed in Section 2(1) are deemed to constitute customer harassment without any such holistic assessment. That list should therefore assist in determining whether particular conduct is “particularly egregious.”
As to the content of the “response policy,” the MHLW offers the following examples. These too are directed primarily at B2C customer harassment and will not necessarily translate to the B2B context, but they are a useful guide to the level of granularity required in order to satisfy the statutory obligation.
As to the “putting in place” of a “system,” the MHLW’s example is to establish arrangements enabling the relevant departments — human resources, customer service, legal, and others — to coordinate appropriately and promptly, and to provide that, where particularly egregious customer harassment occurs, those departments will act together in determining the response to be taken.
Unlike the measures against sexual harassment within the company, the measures against sexual harassment towards jobseekers etc. require companies to formulate rules governing how employees interact with jobseekers etc. As examples of matters to be covered by such rules, the MHLW cites (i) specifying the times at which meetings may be held, (ii) specifying the locations, (iii) the arrangements for conducting meetings, and (iv) specifying which social media platforms may be used for communications. The MHLW does not, however, indicate how restrictive the rules need to be. Accordingly, as regards (i), (ii), and (iv), each company must decide for itself how far it is prepared to permit interactions outside of business hours, business premises, and official communication channels. As regards (iii), examples include restrictions on the number of people present at a meeting (so as to avoid one-on-one meetings) and requiring employees who conduct meetings to report the location, time, and format before or after the event.
Because both the likely perpetrator and the likely victim of Internal Harassment are inside the company, communication and awareness-raising need only extend to persons within the company. With sexual harassment towards jobseekers etc., however — a form of External Harassment — the likely victim is outside the company, and communication and awareness-raising must therefore extend to persons outside the company as well.
As examples of how this may be done, the MHLW cites “pamphlets, websites and the like,” although in practice the latter will generally be the realistic option — for instance, by posting the relevant information on the careers pages of the company’s website.
Where the measures described above are inadequate, the MHLW minister may, depending on the degree of the inadequacy, impose administrative guidance in the form of advice (jogen), guidance (shidou), or a recommendation (kankoku), and, where a recommendation is not complied with, that fact may be made public. The same administrative guidance regime applies under the law to Internal Harassment, but to date no case has proceeded as far as public disclosure. It may therefore be inferred that employers subject to advice, guidance, or a recommendation in relation to Internal Harassment have complied and improved their harassment measures accordingly, and we expect that the same pattern may hold for External Harassment.
In addition, where an employee suffers harassment, the employee may bring a claim for damages against their employer on the basis that the measures described above were inadequate. Inadequate measures thus create the risk that the company will be unable to mount an adequate defense to such a claim.
Note, further, that in the case of customer harassment, if a company’s own employees engage in customer harassment against a supplier or other counterparty, this may constitute an abuse of superior bargaining position under the Antimonopoly Act4 , giving rise to a risk of enforcement action and public disclosure under that act.

[3] “According to the MHLW’s FY 2023 survey, only 0.7% of companies had received a consultation regarding sexual harassment in the job-search context over the preceding three years; yet, among those graduating between FY 2020 and FY 2022, 30.1% had experienced sexual harassment during an internship and 31.9% had experienced sexual harassment during their job search. Whereas 6.3% of employees had experienced sexual harassment at their place of work, a considerably larger number of students and others report having experienced sexual harassment in the course of job-search activities.” (MHLW, Report of the Study Group on the Promotion of Women’s Advancement in the Field of Employment, August 8, 2024.
