What did Japan call India

Japan traditionally called India "Tenjiku" (天竺), which translates roughly to "Heavenly Land" or "Land of Heaven." This name has deep historical roots dating back to when Buddhism traveled from India to Japan via China and Korea, carrying with it Sanskrit terms and concepts. The Chinese transliteration of "Sindhu" (the ancient name for the Indus region) evolved into "Tianzhu" in Chinese, which became "Tenjiku" in Japanese pronunciation. This name was used for centuries and appears in classical Japanese literature, Buddhist texts, and historical documents, reflecting the profound respect Japanese culture held for India as the birthplace of Buddhism.

In modern Japanese, India is called "Indo" (インド), which is a phonetic adaptation of the English word "India" adopted during Japan's modernization period in the late 19th and early 20th centuries. While "Tenjiku" is still understood and occasionally appears in historical or literary contexts, "Indo" is the standard contemporary term used in everyday conversation, media, and official documents. This linguistic shift mirrors Japan's broader engagement with Western terminology and its evolving relationship with India beyond purely religious and cultural connections to include diplomatic, economic, and strategic partnerships in the modern era.
