Although the year of 607 is seen in the halo of the seated statue of Yakushi Nyorai enshrined at the main hall of the Horyu-ji Temple in Nara, it is said, judging from the terms used in its inscription and casting technology employed in the production of the statue, that it was actually produced in the late 7th century.
