Reviewing transcultural perspectives of psychotrauma helps understand its complexities and contextual impacts. This paper summarizes the Japan–Netherlands symposium on psychotrauma held on March 1, 2024. Despite experiencing psychological trauma from World War II and numerous natural disasters, Japan did not actively research post-traumatic stress disorder (PTSD) for nearly 50 years after the war. The Great Hanshin-Awaji Earthquake and the Tokyo subway Sarin gas attack (1995) popularized the term PTSD in Japan and triggered related research. The absence of psychotrauma research in Japan may reflect a form of state-level PTSD, characterized by avoidance. Japan’s collectivist culture, stigma against seeking psychological help, view of patience as a virtue, survivor guilt, and moral injury were potential related factors. Additionally, sociocultural factors (e.g., insufficient collective grieving and focusing on post-war reconstruction) were discussed as potential hinderances to discussing war experiences. From a European perspective, we examined how “Konzentrationslager” (KZ) syndrome, a trauma-related disorder, evolved independently into diverse conceptual frameworks, ultimately contributing to the acceptance of PTSD following its introduction in 1980. Beyond state compensation for concentration camp survivors, advocacy by feminist movements and veterans' groups increased awareness of psychotrauma across Europe, fostering scholarly research and public discourse. Both PTSD and KZ syndromes are diagnostic categories shaped by specific historical and cultural contexts and should not be regarded as simple, universally applicable medical conditions. They reflect how trauma is interpreted and responded to differently depending on cultural, political, and historical factors.No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1880-91622420252000年天皇訪蘭にかんするメディア報道について―「皇后さまと白い菊」―3348ENTomoyoNAKAO10.18926/68294No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671552023連合国軍捕虜問題：真実な和解のための一側面―『戦争トラウマ記憶のオーラルヒストリー：第二次大戦連合軍捕虜とその家族』著作紹介―1129ENTomoyoNakao10.18926/65122No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1880-9162222022「バターン死の行進」研究ノート2734ENTomoyoNakao10.18926/643342022年9月 バターン・コレヒドール防衛者の会記念の会（ADBC-MS）の報告」およびジャック・ブレイディの残した記録のリスト<br>
