Angen onga no nikki (安元御賀日記)
Angen onga no nikki is a diary in which the celebration of Emperor Goshirakawa's 50th birthday was recorded by FUJIWARA no Takafusa, a waka poet who lived in the Heian period. It is also called Angen onga ki. This celebration was held at the Hoju-ji Temple (Kyoto City) in April and May, 1176. There are several different kinds of manuscript. Gunsho Ruiju (Classified Documents) contains it.
The manuscript made in the early Kamakura period and now owned by The Tokugawa Art Museum was designated as an important cultural property in 2005.
