'1 in 8 Have Witnessed It': Survey of 10,000 Reveals Reality of BtoB Customer Harassment by Employees

A survey of 10,000 employed individuals conducted by Asmarq Inc. has revealed that 1 in 8 (11.9%) have witnessed their own company's employees committing customer harassment (known as 'kasuhara' in Japan) against business partners. This research comes as new legal obligations requiring all businesses to implement anti-harassment measures are set to take effect on October 1, 2026. The rate of witnessing such incidents was particularly high among managers at 27.4%. However, approximately 35% of those who witnessed harassment did nothing, with the primary reason being a belief that 'reporting it would be useless' (44.9%). These findings highlight the significant internal risk of BtoB harassment for companies and point to challenges within their internal reporting systems.
