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

1. Introduction

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

  • With respect to customer harassment, although the proportion of employees who had suffered customer harassment in recent years exceeded the proportion who had suffered sexual harassment, relatively few companies had taken steps to address it; and
  • With respect to sexual harassment towards jobseekers etc.3 , the proportion of jobseekers etc. who experienced sexual harassment during their job search exceeded the proportion of employees who experienced sexual harassment at their place of work.

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).

2. Definitions of Customer Harassment and Sexual Harassment towards Jobseekers etc.


(1) Customer harassment

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

  • Demands that are wholly unfounded, or that bear no relation whatsoever to the goods or services in question
  • Demands that go significantly beyond the services contemplated by the contract
  • Demands that are extremely difficult or impossible to satisfy
  • Unwarranted demands for compensation
  • Physical attacks (assault, bodily injury, etc.)
  • Psychological attacks (threats, defamatory statements, injury to reputation, insults, abusive language, demanding that an employee kneel in apology, etc.)
  • Intimidating conduct
  • Persistent, repeated conduct
  • Conduct that restrains the employee (refusing to leave, occupying the premises, confinement, etc.)

(2) Sexual harassment towards jobseekers etc.

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.

3. The Required Measures


(1) Overview

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).

Customer harassment

Sexual harassment towards jobseekers etc.

Clarification of the employer’s policy,
and communication of and awareness-raising as to that policy

  1. Clarify a policy of responding firmly to customer harassment and of protecting employees, and communicate it to, and raise awareness of it among, employees.
  2. Communicate to employees what constitutes customer harassment and the response procedures established in advance.
  1. Clarify a policy prohibiting sexual harassment towards jobseekers etc., and communicate it to, and raise awareness of it among, employees.
  2. Communicate to, and raise awareness among, employees of a policy of dealing strictly with any person who commits sexual harassment toward a job applicant, and of the measures that will be taken.
  3. Clarify in advance the rules applicable to job-search activities, and communicate them to, and raise awareness of them among, employees and jobseekers etc.

Establishment of reporting channels

  1. Designate a consultation contact point in advance and communicate it to employees.
  2. Ensure that the persons staffing the contact point are able to respond appropriately.

Prompt and appropriate response after an incident

  1. Ascertain the facts promptly and accurately.
  2. Take appropriate measures to accommodate the victim.
  3. Take measures to prevent recurrence.

 

  1. Ascertain the facts promptly and accurately.
  2. Take appropriate measures to accommodate the victim.
  3. Take appropriate measures in respect of the perpetrator.
  4. Take measures to prevent recurrence.

Measures necessary to ensure that the response is effective

  1. Establish in advance a policy for dealing with customer harassment considered particularly egregious, communicate that policy to employees, and put in place a system capable of implementing it.

 

Other measures

  1. Take measures necessary to protect the privacy of complainants and others involved, and communicate them to employees.
  2. Provide that no person will be subjected to adverse treatment by reason of having raised a complaint or the like, and communicate this to, and raise awareness of it among, employees.
  1. Take measures necessary to protect the privacy of complainants and others involved, and communicate them to employees.
  2. Provide that no employee will be dismissed or otherwise subjected to adverse treatment by reason of having cooperated in ascertaining the facts or the like, and communicate this to, and raise awareness of it among, employees.

Of these measures, the following warrant particular attention when compared with the Internal Harassment rules.

(2) Customer harassment: Communicating the response procedures for customer harassment (item (b) above)

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.

  • Requiring the employee to report the matter immediately to a manager or supervisor and to seek instructions on how to handle the situation on the spot.
  • To the extent possible, not requiring the employee to handle the matter alone, and, where necessary, having a manager or supervisor take over from the employee.
  • Making an audio or video recording of the exchange with the customer.
  • Where the employee has given a full explanation and the demands are nevertheless repeated, asking the customer to leave the premises, or terminating the call, after a set period of time.
  • Reporting to the police any conduct that may constitute a criminal offense, such as assault, bodily injury, or threats.
  • Where the matter cannot be resolved on site, escalating it to head office or a regional headquarters and seeking instructions.
  • Where legal proceedings are required, coordinating with the legal department and consulting outside counsel.

No particular method of communication is prescribed. The MHLW’s examples include preparing and distributing a manual and holding training sessions and seminars.

(3) Customer harassment: Policy and framework for dealing with particularly egregious customer harassment (item (h) above)

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.

  • Reporting to the police any conduct that may constitute a criminal offense, such as assault, bodily injury, or threats
  • Refusing to sell goods or provide services to the person concerned
  • Barring the person concerned from entering the company’s stores and facilities
  • Applying for a provisional disposition order under the Civil Provisional Remedies Act (Act No. 91 of 1989)

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.

(4) Sexual harassment towards jobseekers etc.: Clarifying in advance the rules applicable to job-search activities (item (iii) above)

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.

(5) Sexual harassment towards jobseekers etc.: Communicating the job-search rules and the consultation contact point to jobseekers etc. (items (iii) and (iv) above)

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.

4. Risks of Inadequate Measures

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.
