Ichijo Taisai held at Ichijo Shrine in Nakamura City is one of the three biggest festivals in Kochi Pref. This festival is dedicated to the memory of the Ichijo family, who had taken refugee from Onin War (1467-1477) in Kyoto and built a town in this place. The festival is also familiarly called “Ichijoko-san” by the local people. When Ichijo Norifusa, ex-Kanpaku (the first secretary to the emperor), moved to this province in 1475, he relocated Atago Shrine, which was on Mt. Komoriyama at the center of the town, to another place and constructed his residence, which were called “Nakamura Palace.” After the Tosa Ichijo clan was exiled from this province during the Tensho era (1573-1591), the bereaved retainers built a memorial hall to enshrine the successive heads of the Ichijo clan in 1607. Later in 1862, Ichijo Shrine was constructed on the part of the ruins of Nakamura Palace where the mausoleum of the Ichijo clan was located. Since then a big festival of Ichijo Taisai has been held at this shrine. In the precinct are several ruins pertaining to the Ichijo family such as “Fujimi-no Goten (wisteria viewing hall)” and “Kesho-no Ido (dressing well).”
