In 2026, the harvest moon falls on Friday, September 25. That evening at Magatama Pond in the Outer Shrine (Geku) of Ise Jingu, the Jingu Kangetsukai — a moon-viewing gathering — takes place, the pond-side performance stage bathed in moonlight as autumn arrives in Ise.

What is the Jingu Kangetsukai?

Selected tanka and haiku poems submitted from across Japan are recited by the Shrine's court musicians in the classical style of the Reizei school, followed by performances of gagaku court music and bugaku dance. This year's set theme is "fields" (no). The gathering begins at 6 p.m. on Friday, September 25, at the performance stage on Magatama Pond at the Outer Shrine.

A moonlit tradition since 1898

The gathering traces back to 1898 (Meiji 31), when Reizei Tamemoto, then chief priest of the Shrine, held a moon-viewing poetry gathering on Kurata Hill. Since 1948 it has been organized by the Jingu administration office.

A rare year: the "named moon" and the full moon two days apart

The harvest moon is the moon of the fifteenth night of the eighth month in the old lunar calendar — not necessarily the astronomical full moon. According to the National Astronomical Observatory of Japan, in 2026 the full moon comes two days later, on September 27. A gap this wide last occurred in 2017 and will not recur until 2043, so the moon admired on the night of the 25th will be just short of full.
