The India–Japan partnership is characterized by strategic alignment, scientific collaboration, and societal transformation. Rooted in civilizational ties and mutual respect, this bilateral relationship has evolved into a dynamic framework for addressing global challenges through science, technology, and innovation (STI). As leading democracies in Asia, both nations recognize the importance of leveraging STI for economic advancement, inclusive development, regional stability, and climate resilience. The establishment of the India-Japan Science Technology and Innovation (STI) Forum in 2023 by Keio University of Japan and Indian Institute of Science Bengaluru of India marked a significant milestone in this partnership. The forum aims to foster innovation ecosystems, enhance maritime security cooperation, and expand multilateral engagements. Inclusive, adaptable, and ethically grounded frameworks connecting strategic ambition with tangible social impact would address the challenges such as institutional inertia, cultural differences, and structural barriers in academic and industrial collaboration. This volume explores the multifaceted dimensions of the India-Japan partnership, navigating geopolitics, innovation, and societal challenges in varied fields crucial to the overall ecosystem of global co-existence. This consortium of scholarly contributions attempts to analyze the bilateral collaborations from varied angles to formulate a blueprint towards equitable, sustainable, and future-oriented development across the Indo-Pacific and beyond.
