The town of Usuki in eastern Oita prefecture is known for its thousand-year-old stone buddha statues, recognized as National Treasures by the Japanese government. Eight different groupings of statues can be viewed from a walking path that circles the cliffs where the buddhas were carved. Extensive renovations in both the 1970s and 1990s have made the statues look simply amazing for having been created over a millenium ago. For more details on some of the statues and the site itself, see the related article (link on the right side of this page).
