Gangō-ji stands within Naramachi, but its history begins at Asuka-dera, also known as Hōkō-ji, traditionally regarded as Japan’s first full-scale Buddhist temple. When the capital moved to Heijō-kyō in 710, the institution was transferred and rebuilt in Nara under the name Gangō-ji. Its original precinct once occupied a far larger part of today’s neighbourhood.
Fires, political change and urban growth reduced that complex over centuries. The surviving Gokurakudō hall and Zen room preserve the memory and material of the monastic quarters rather than the vanished monumental core. Both are National Treasures, and the precinct forms part of UNESCO’s Historic Monuments of Ancient Nara.
