Critical reflections on the development of the Gunma Declaration on Heritage Ecosystems: Challenges, contradictions, and opportunities for Indigenous Peoples

Abstract

In January 2025, a symposium convened by Japan’s National Committee of the International Council on Monuments and Sites (ICOMOS) adopted the Gunma Declaration on Heritage Ecosystems, a new World Heritage framework that, for the first time, explicitly references Indigenous Peoples and the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP) as part of the World Heritage system’s “authenticity” criterion. This commentary offers a critical and reflexive analysis of the declaration’s development, drawing on the author’s experience as a symposium participant. It examines the tension between the declaration’s transformative potential – particularly its alignment with Indigenous understandings of the inseparability of nature and culture – and the structural exclusion, silencing, and erasure of Indigenous voices witnessed during its drafting. The analysis highlights how colonial narratives of “contaminated” Indigenous cultures, “purity,” and “authenticity” continue to determine Indigenous legitimacy in practice. This commentary argues that the Gunma Declaration’s advances risk becoming forms of symbolic recognition and illusory inclusion unless translated into enforceable state practice. Ultimately, this commentary is offered as an act of Indigenous resurgence, urging that the future of heritage governance be grounded not in institutional rhetoric but in Indigenous self-determination and the courage to imagine the World Heritage system otherwise.
