This article (written in Japanese) demonstrates how theories and methods of reconciliation and psycho-social healing can contribute to policy making and civil society initiatives in East Asia in terms of how to tackle deep-rooted historical conflicts over contested memories and politicized identities. It explores a culturally-sensitive use of symbols, ceremonies, and discourse development that can humanize the exchanges between the divided East Asian nations, advocates the development of sustained, broad-based social platforms of communication (with the European precedent in mind), and proposes an expansion and diversification of channels and stakeholder groups capable of creating a more tolerant social space for candid international exchanges.
