Henoko boat capsizing investigation

Overview

In March 2026, two small boats belonging to an anti-helicopter-base protest group capsized off Henoko, Okinawa, during a trip for Doshisha International High School. The accident resulted in the deaths of 17-year-old student Chika Takeshi and 71-year-old captain Sō Kanai.

A third-party committee report released in late July 2026 concluded that the school’s safety-management system was “significantly inadequate,” noting failures in site inspections, travel planning, and student briefings. Following the report, the bereaved parents filed criminal complaints in Tokyo against eleven individuals, including school officials and members of the protest group, for professional negligence resulting in death.

By August 12, 2026, the investigation escalated as the 11th Regional Coast Guard Headquarters conducted searches of the homes of the vessel ‘Heiwa Maru’ captain and executives of the ‘Helicopter Base Opposition Council.’ Authorities seized mobile phones and computers as part of the ongoing probe into professional negligence.

In late August 2026, Doshisha International High School officially announced the cancellation of its 2026 school trips to Okinawa. During a briefing for parents, the school stated that two teachers involved in the trip—who face criminal charges for professional negligence—will be reassigned to roles without direct student contact starting in the second semester. The briefing was met with significant dissatisfaction from parents after the school initially attempted to bypass a question-and-answer period. Additionally, the school reported that another teacher involved in the Okinawa trip died on August 23, though no causal link to the original accident has been established. The school’s principal has been dismissed, and the chairperson of School Corporation Doshisha has expressed intentions to resign. The corporation also plans to investigate matters concerning governance and the educational neutrality of its curriculum.
