The major sites include the ruins of the Asuka Palace and Fujiwara Palace related to early state-building, the remains of Japan's first full-fledged capital, Buddhist temple ruins and ancient burial mounds. Among the burial mounds are the Takamatsuzuka mounded tomb, known for its vividly colored murals, and the Kitora mounded tomb, featuring the oldest existing astronomical chart in East Asia. A UNESCO advisory body recommended adding the sites to the World Cultural Heritage list in June. With the addition, Japan now has 22 cultural and five natural World Heritage sites.
