Wichtiges Kulturgut Japans
Ueno Park occupies land once belonging to Kan'ei-ji, founded in 1625 in the "demon gate", the unlucky direction to the northeast of Edo Castle. Most of the temple buildings were destroyed in the Battle of Ueno in 1868 during the Boshin War, when the forces of the Tokugawa shogunate were defeated by those aiming at the restoration of imperial rule. In December of that year Ueno Hill became the property of the city of Tokyo, other than for the surviving temple buildings which include the five-storey pagoda of 1639, the Kiyomizu Kannondō (or Shimizudō) of 1631, and approximately coeval main gate (all designated as Important Cultural Properties of Japan).
