The Japan Coast Guard interviewed students from Doshisha International High School after two small boats capsized off the coast of Henoko in Okinawa [1], [2].
This incident highlights the potential dangers of high-speed recreational boating in unpredictable coastal waters, particularly when students are involved in maritime activities. The rescue operation required significant coordination to ensure all passengers were recovered from the sea.
The Japan Coast Guard's 11th Regional Coast Guard Headquarters conducted the interviews to determine the cause of the accident [1], [2]. According to the dossier, two boats overturned during the excursion [2]. One female student remained in the water for more than one hour before rescuers reached her [2].
Students described a frightening environment leading up to the capsizing. One student said the vessels were traveling at a considerable speed, which felt scary [1]. Another student said that while returning, the color of the sea suddenly darkened and the waves became rough [1].
Questions regarding the operation of the vessels also surfaced during the investigation. One student said that while discussing boat operation with the captain, the captain suggested they try steering. The student said they moved to an area where it was safe to operate the boat before attempting to steer [1].
Authorities are continuing to investigate the sequence of events involving Captain Kanai and the students to determine if speed or sudden weather changes were the primary catalysts for the capsizing [1], [2].
“かなりのスピードが出ていて、少し怖かったです”
The investigation focuses on the intersection of vessel speed and sudden environmental shifts. The testimony regarding a student attempting to steer the boat suggests the Coast Guard may examine whether operational errors or a lack of professional oversight contributed to the instability of the two vessels in roughening seas.
