In traditional Japanese culture, India is Tenjiku (the country of heaven). Today, Japan is India’s largest source of aid and has secured a key role in supporting infrastructure development, financing projects like the Western Dedicated Freight Corridor, the Delhi-Mumbai Industrial Corridor, and the Bangalore Metro Rail Project.
尽管此前从未有日本天皇到访印度，但印日双边关系十分深刻。在传统日本文化中，印度被称为天竺国（天堂之国）。如今，日本是印度最大的援助国，并且在支持印度基础设施开发方面起着关键作用，为西部货运专线（Western Dedicated Freight Corridor）、德里-孟买产业走廊和班加罗尔地铁工程提供资金。
