Earned a Ph.D. in Maritime Sciences from the Graduate School of Maritime Sciences, Kobe University, in 2016. Served as Security Manager at Mandarin Oriental Tokyo and as Emergency Response Coordinator and concurrently Manager of the Health and Safety Section at the Okinawa Institute of Science and Technology Graduate University (OIST) from 2018 to 2021. Subsequently held positions as Professor and then Specially Appointed Professor at Kyushu University from 2021 to 2024. As a practitioner and researcher in crisis management and safety management, developed, implemented, and provided education and training for BCM (Business Continuity Management) across these organizations and academic institutions.
During my tenure with the Japan Coast Guard (1984–2004), I was engaged in activities to prevent maritime accidents, counterterrorism efforts, and research on anti-smuggling measures in the United States. While serving with the Japan Transport Safety Board (2009–2016), I completed the Accident Investigation Basic Course at Cranfield University in the United Kingdom (2011) and worked as an accident investigator, conducting numerous accident investigations, analyses, and preparing reports. From 2011 to 2016, I was appointed as a Correspondence Group Analyst for the IMO Sub-Committee on Implementation of IMO Instruments (III) and served as an IMO Consultant. In 2014, I conducted a National Training Course on Marine Casualty and Incident Investigation for Philippine government officials.
At OIST, I developed a Safety Management System (SMS) to prevent accidents, contributing to accident prevention during laboratory experiments and field activities. Additionally, I established a Risk Management Committee, visualized major risks across the institution, prioritized risk mitigation measures, and implemented a system for efficient risk control using limited resources.
At Kyushu University, I engaged in research on accident prevention and delivered lectures on preventing accidents in mountainous and marine environments. These lectures equipped students with knowledge about potential accident factors in such settings and taught them methods to proactively prevent accidents.
