The Archaeological Institute of Kashihara (奈良県立橿原考古学研究所, Narakenritsu Kashihara Kōkogaku Kenkyūsho) was established by the prefectural government of Nara to study and safeguard the many archaeological sites found within the prefecture. For instance, the institute was involved in the excavation of the Takamatsuzuka Tomb in the 1970s. Located at the base of Mount Unebi, one of the three Yamato mountains, the institute has opened a museum to the public.
The Institute's museum has three main exhibition rooms. The first room covers the Jomon Period (13,000 BC to 300 BC) and the Yayoi Period (300 BC to 300 AD), the second room covers the Kofun Period (300-538), and the third room covers a large stretch of time from the Asuka Period (538-710) to the Muromachi Period (1338-1573). The museum displays a number of informative maps and dioramas in addition to the archaeological artefacts.
