This article summarizes the results of archaeological research on some 20 Japanese garden sites dating from the fourth to twelfth centuries A.D., emphasizing the site plan, remains of structures, stone groupings, and ponds. Associated plant remains from five sites are tabulated and briefly discussed. I introduce some early Chinese and Korean antecedents and provide historical context. Gardens with rectangular ponds were introduced from the continent in the Asuka Period (A.D. 538-710). From the Nara Period (A.D. 710-794), garden making was naturalized in a Japanese asymetrical curving style in which structures were located away from the central axis. The gardens discussed here represent a small sample of the original gardens. They include two early examples of an adopted continental style (i.e., Uenomiya and Furumiya), a garden from an imperial palace site, gardens enclosing Heian Period shinden type architecture (raised residence with side wings) and its adapted Pure Land form, and a garden associated with the palace of a retired emperor. Plantings show a combination of flowering trees and shrubs, many introduced from the continent, combined with native deciduous and evergreen trees. Continental examples of gardens with rectangular ponds belong to royal palaces and were symbols of royal authority, aswere the examples dated to the Asuka Period. In the Heian Period, state gardens such as Shinsen'en were used for state functions and required ample space and simple organization, while gardens sponsored by elite courtiers such as the Fujiwara show the expression of Buddhist belief. In the Toba Rikyu, built by retired emperors under a complex insei (retirement) system, imperial mausolea shared the landscape with mansions, Buddhist temples, and chapels. Groupings of stones, curving streams, dry landscapes, and low waterfalls probably all occurred as early as the Nara Period.
