The earliest recorded Japanese gardens were the pleasure gardens of the Emperors and nobles. They are mentioned in several brief passages of the "Nihon Shoki", the first chronicle of Japanese history, published in 720. In the spring of the year 74, the chronicle recorded: "The Emperor Keikō put a few carp into a pond, and rejoiced to see them morning and evening". The following year, "The Emperor launched a double-hulled boat in the pond of Ijishi at Ihare, and went aboard with his imperial concubine, and they feasted sumptuously together". And in 486, "The Emperor Kenzō went into the garden and feasted at the edge of a winding stream".
