Based on these points, researchers agree on the most part that while Kudara Kannon-zo was made at a later time than the statue at the honzon of Yumedono and others, it is older than the Sho Kannon-zo (statue of Sho Kannon) at Yakushi-ji Temple Toin-do and Yume-Chigai Kannon-zo (statue of Yume-Chigai Kannon) at Horyu-ji Temple, among others, which show the influence of the sculpture of the early Tang period, and that it is the work of roughly around the middle to late seventh century.
こうした点から、百済観音は夢殿本尊像などよりはやや年代が下るが、初唐彫刻の影響が見られる薬師寺東院堂の聖観音像や法隆寺の夢違観音像などよりは古く、おおむね7世紀半ばから後半の作とする点で研究者の意見はほぼ一致している。
