Yubunezawa Stone Circle (湯舟沢環状列石, Yubunezawa kanjō resseki) is an archaeological site with the remains of a Late Jōmon (c. 4000 BP) stone circle in what is now the city of Takizawa, Iwate Prefecture, Japan. The site was designated a Prefectural Historic Site in 2013.^[2][3][3]

The stone circle was discovered in 1990 during construction-related survey and excavation in what was then the village of Takizawa.^[1] Extending some 20 metres (66 ft) north to south by 15 metres (49 ft) east to west, the circle comprises a number of variously shaped groups of stones.^[1] Scientific analysis of the numerous man-made holes beneath the stones indicates that this was a communal burial and ritual site, facing Mount Yaji (528 metres (1,732 ft)).^[1][4] While there were further graves without a stone marker, the absence of postholes or other evidence for dwellings in the circle's vicinity demonstrates the distinction and separation of spaces for living from those for burial and spirituality.^[1][5] A pathway for transporting stones to the site was also found, along with ceramics and lithics.^[1][5][6]

The same summer that the stone circle was discovered, the village decided to preserve the site and make the land public.^[1] Since 1998, it has been open to the public as an historical park, complemented by the exhibition room at the adjacent Takizawa City Buried Cultural Properties Center.^[1] The original remains are preserved beneath the surface, as when found, while the circle has been reconstituted with 823 stones.^[7] The surrounding area has been landscaped with plants in keeping with those of Jōmon times.^[7]
