India and Japan have spent decades building one of Asia's most consequential partnerships. From the Mumbai-Ahmedabad bullet train project and Japanese investments in Indian manufacturing to cooperation in semiconductors, critical minerals and clean energy, the relationship today stretches far beyond diplomacy. Japan is one of India's largest investors. Indian professionals are increasingly finding opportunities in Japan. The two countries are also working together on everything from supply chains to artificial intelligence.Over the years, India has borrowed many ideas from Japan. Manufacturing practices.
