Dial Service to Host Symposium on Sustainable Internal Whistleblowing Systems on June 1, 2026

Dial Service Co., Ltd. (Head office: Chiyoda-ku, Tokyo; Representative Director: Yuri Konno) announced that it will hold a symposium titled “June 1 Is Internal Whistleblowing System Day: Toward Sustainable Internal Whistleblowing Systems” on Monday, June 1, 2026, in conjunction with the commemorative day established by the company. The year 2026 marks the enforcement of the amended Whistleblower Protection Act, which will take effect on December 1, 2026. As a result, companies will face heightened scrutiny over the effectiveness and sustainability of their internal whistleblowing systems. The symposium will feature lawyers familiar with the Whistleblower Protection Act and internal reporting systems, corporate practitioners responsible for operating such systems, and clinical psychologists involved in frontline whistleblowing response. Drawing on the latest legal developments and practical challenges, the event will examine not only the systems themselves but also how to support the people and organizations responsible for operating them, discussing the future of sustainable internal whistleblowing systems from multiple perspectives. The program includes keynote speeches titled “Issues Left by the Amended Act: The Problem of Abusive Reporting” by attorney Teruyoshi Endo of Teruyoshi Endo Law Office, and “Preventing Internal Whistleblowing Systems from Becoming Exhausted” by Dial Service clinical psychologist Rie Suzuki. A panel discussion will include Shinya Hosoda, leader of Aeon Co., Ltd.’s Philosophy and Vision Promotion Team, and Katsumi Ishikawa, General Manager of the Legal Department in Hakuto Co., Ltd.’s ESG Management Promotion Unit. Corporate representatives will share operational ideas and challenges in their whistleblowing systems, raising topics that help participants explore more sustainable approaches. A networking session among participants will follow the symposium. The event will be held on Monday, June 1, 2026, from 1:30 p.m. to 4:00 p.m., with registration starting at 1:00 p.m. A participant networking session will be held at the same venue until 5:00 p.m. The venue is “Akane” on the 3rd floor of Kudan Kaikan Terrace, 1-6-5 Kudanminami, Chiyoda-ku, Tokyo. The event is intended for people in charge of compliance and harassment prevention departments, related stakeholders, and anyone interested in internal whistleblowing systems. Capacity is limited to 80 participants, with advance registration required. “Internal Whistleblowing System Day” was established by Dial Service on June 1 after receiving certification from the Japan Anniversary Association in 2025, with the aim of raising awareness of the importance of internal whistleblowing systems. In 2003, the company opened Japan’s first private-sector external contact point for internal whistleblowing systems and has worked to create environments where corporate employees can speak up, report concerns, and seek advice with confidence. June 1 is also the date on which the amended Whistleblower Protection Act came into force in 2022, making the operation of internal whistleblowing systems a corporate obligation for the first time. The timing also reflects the fact that workplace issues tend to surface after some time has passed since the start of a new fiscal year, and that the job-hunting season is considered a period when harassment toward students is more likely to occur.
