Okakura Kakuzō , also known as Okakura Tenshin (岡倉 天心), was a Japanese scholar and art critic who in the era of Meiji Restoration reform promoted a critical appreciation of traditional forms, customs and beliefs. Outside Japan, he is chiefly renowned for The Book of Tea: A Japanese Harmony of Art, Culture, and the Simple Life (1906). Written in English, and in the wake of the Russo-Japanese War, it decried Western caricaturing of the Japanese, and of Asians more generally, and expressed the fear that Japan gained respect only to the extent that it adopted the barbarities of Western militarism.

The Book of Tea A Japanese Harmony of Art, Culture, and the Simple Life (1906) by Okakura Kakuzō (1906) is a long essay linking the role of chadō (teaism) to the aesthetic and cultural aspects of Japanese life and protesting Western caricatures of "the East".
