Key Points
School approved boat program without inspecting boats or discussing safety.
Teachers ignored warnings that captain's colleague died at sea and boats were protest vessels.
Third-party panel found school lacked basic safety rules and delegated all decisions to captain.
Parents filed criminal complaint against 11 people including principal and school officials.
A third-party investigation panel found Doshisha International High School in Kyoto Prefecture responsible for a March 16 boat accident off Okinawa that killed two people. The panel said the school conducted no preliminary site inspections, relied on unfounded trust in the boat captain, and repeated unsafe procedures from prior years without verification. The deaths included student Tomoka Takeishi, 17, and captain Hajime Kanai, 71. Parents have filed a criminal complaint against 11 people.
How the school approved an unsafe program
The boat program began in 2022 when a second-year teacher met with Hajime Kanai, a local church pastor and boat captain, during a site visit for a peace education trip. Kanai proposed the boat activity on the spot. The teachers approved it for the following year without inspecting the actual boats or discussing safety. No travel agency safety review occurred because the school ran the program independently, bypassing standard safety checks. The panel found that discussions about boat safety never happened and no teacher raised objections.
Why teachers ignored warning signs
Teachers knew Kanai had mentioned that another captain died in a protest-related incident at sea, and some staff recognized the boats as protest vessels. Despite these red flags, the school continued the program unchanged. One teacher suggested inspecting the boats before the 2023 trip, but a colleague dismissed the idea, saying prior-year methods needed no changes. The panel concluded teachers suffered from “groundless overconfidence” and failed to conduct proper due diligence. Teachers admitted repeating unsafe precedent without correct handover of procedures.
What the investigation revealed about organizational failures
The third-party panel, made up of three lawyers, interviewed 48 people including 17 school staff members. It found the school lacked basic safety rules, crisis management manuals for water accidents, and procedures for medical evacuation. The school delegated all safety decisions to the boat captain without verification. The panel stated the school’s organizational culture treated safety as someone else’s responsibility. Panel chairman Toru Watanabe said the school’s practices were “unbelievably careless” with safety awareness “completely absent.”
Criminal charges and next steps
On July 30, Tomoka Takeishi’s parents filed a criminal complaint with the Nakagusuku Coast Guard Office accusing 11 people of professional negligence resulting in death and injury. Named defendants include the school principal, a head teacher, educators, and officials from the boat operator. In May, Japan’s transport ministry filed a separate criminal complaint against the deceased captain for operating a passenger boat without proper registration. The school has committed to revising safety manuals and crisis management procedures.
Final Thoughts
The investigation exposes how institutional complacency and blind repetition of prior practices can override basic safety obligations. For schools organizing off-campus activities, the case underscores the legal and moral imperative to conduct independent safety verification rather than assume prior procedures remain valid.
