NAHA, Japan - The Japan Coast Guard has searched a private high school in Kyoto Prefecture on suspicion of professional negligence resulting in death and injury following a fatal boat accident in Okinawa in March, investigative sources said Tuesday.

The family of a 17-year-old female student who died in the accident during a "peace education" school trip off the Henoko area in Nago filed a criminal complaint with the coast guard earlier this month against the principal of Doshisha International Junior and Senior High School and others.
