History and Cultural Evolution of Japanese Moon-Viewing#
The custom of moon-viewing was introduced to the Japanese imperial court from Tang Dynasty China during the early Heian period. Historical records indicate that the earliest recorded royal moon-viewing banquet took place in the year 909 under Emperor Daigo.
For court nobles, the pinnacle of aesthetic refinement was not to gaze directly upward into the sky, but to admire the soft reflection of the moon shimmering across pond surfaces or swirling in sake cups. Emperor Saga's legendary boat parties upon Osawa Pond at his Saga Imperial Villa (now Daikakuji Temple) became the archetypal symbol of this poetic pastime, where guests composed waka poetry to the resonant harmonies of court gagaku music.
During the Muromachi and Edo periods, this aristocratic pastime spread widely to the warrior class and the general populace. Among agricultural communities, the festival coincided with the harvest of taro roots, earning it the affectionate moniker Imo Meigetsu (Taro Moon). It transformed into a thanksgiving harvest festival dedicated to deities and ancestors. The beloved custom of displaying Japanese pampas grass (susuki) resembling rice ears alongside rice dumplings (tsukimi dango), seasonal taro, chestnuts, and edamame firmly established itself during this era.
