NARA, NARA-KEN, JAPAN - 2017/11/09: Excavation of the Heijo Palace in Nara revealed the remains of an 8th-Century pond garden: the To-in Garden, workers preparing the ground discovered the remains of a stream garden - a yarimizu that dates to the same period as the palace itself. The winding stream echoes the Chinese, Korean and early Japanese tradition of a stream banquet during which guests attempted to come up with an original poem before cups of sake. All that remain at To-in are the stream and the rocks placed along the banks of the stream and anticipates certain aspects of later Japanese garden elements.
