What the Heian period means
The Heian period is the division of Japanese history that runs from 794, when Emperor Kanmu moved the capital to Heian-kyo, the city that became Kyoto, to the late twelfth century, when Minamoto no Yoritomo established a warrior government at Kamakura. Its end depends on where the start of the Kamakura period is placed, and general histories give years through the 1180s up to 1192. The Nara period precedes it.
For cultural properties the Heian period is when Buddhist art and architecture took on a distinctly Japanese character. Early in the period the monks Saicho and Kukai brought the Tendai and Shingon schools from China, and esoteric statues and mandalas were produced in large numbers. Wooden sculpture of this phase is typified by weighty figures carved from a single block, the Ichiboku-zukuri method. From the middle of the period Pure Land Buddhism spread, and halls dedicated to Amida were built across the country; the Phoenix Hall of Byodoin, completed in 1053, and the Konjikido of Chusonji, finished in 1124, are the leading survivors. Sculptors perfected the joined-block Yosegi-zukuri technique and a gentle, rounded style spread. In architecture, cypress-bark roofs and softly curving eaves were refined into what would later be called the Wayō manner.
Art historians sometimes call the later half of the period the Fujiwara period and give the earlier half other names, such as the Jogan period. These divisions rest on style and do not match the period divisions used in the national records.
How the period appears in records
Building records in the national database divide the period into early, middle and late in the period field. That division does not always match art-historical habit. The Phoenix Hall of 1053 is entered as mid-Heian, while the Konjikido of 1124 is entered as late Heian, so a building that art historians treat as the classic Fujiwara-period work sits in the middle phase in the records. When an article gives a phase, it should use the value in the record and not mix it with art-historical divisions.
Records for art objects often give only Heian as the period. Where the year of making is known it appears in the date field: a seated Dainichi owned by Arida City in Wakayama, for instance, is dated to 1062 by an ink inscription inside. Where no year is known, the commentary gives a range, such as around the middle of the eleventh century.
Works from the end of the Heian period and the beginning of the Kamakura period are sometimes entered as spanning both, partly because the boundary year is disputed and partly because style changed gradually across it.
