A passage in the Nihon Shoki states that in 577 King Wideok of Baekje sent to the Yamato polity another Buddhist image, a temple architect, and a maker of images. The passage clearly indicates that the Japanese still needed Korean artisans skilled in metal casting techniques and knowledgeable about specific iconography to construct images. In 584, a stone statue of Maitreya and another image simply identified as a Buddha by the Nihon Shoki were sent as part of a diplomatic exchange and are the last official, royally commissioned Baekje images recorded to be sent to Japan in the 6th century. Such exchanges, both official and unofficial, were integral in establishing early Japanese Buddhist sculpture.
