On April 4, 2023, the 10th trial of Seiichi Katsurada, the CEO of the Shiretoko Marine Co., began at the Kushiro District Court regarding the sinking of the KAZU I tour boat in Hokkaido in 2022, which led to 26 deaths and missing persons. The victims' families have expressed their determination that exposing the truth publicly is the only way to show sincerity towards those lost. Despite facing numerous questions, Katsurada has usually responded with a phrase claiming he does not remember the events leading up to the accident. During the proceedings, a lawyer representing the victims' families challenged Katsurada about his responsibilities and knowledge regarding the weather conditions on the day of the incident, emphasizing that the tour boat's operational manager has an obligation to know the weather and sea information. Katsurada admitted to lacking knowledge about essential navigation aspects, such as the depth along the tour boat's course and claimed he relied on the captain for navigation decisions. He acknowledged viewing the weather forecast, but did not comprehend the weather maps adequately, indicating a significant gap in required knowledge by operational standards. The Japan Transport Safety Committee's investigation report cited a cold front from a low-pressure system affecting the Sea of Okhotsk during the time leading to the accident. When questioned if better knowledge could have changed the decision to set sail, Katsurada weakly admitted that a different conclusion might have emerged given that 'this accident occurred as a result'. His ambiguous responses continue to evoke strong emotions from the victims' families, who seek true accountability for the tragic loss of life.
