Shimai Atago — The Year's Last Atago Festival Day
Seasonal EventsWhat Is Shimai Atago?
December 24th is "Shimai Atago" (the Last Atago Day) in Japan. The festival day of Atago Gongen, a deity worshipped for protection against fire, falls on the 24th of every month, and the year's final observance, on December 24th, is known as "Shimai Atago" or "Osame Atago" (the Closing Atago).
What Is Atago Worship?
There are said to be roughly 900 Atago shrines across Japan, with the head shrine located atop Mount Atago in Kyoto.
- Guardian against fire: long worshipped widely for protection against fires and blazes
- The festival day: the 24th of every month is Atago Gongen's festival day, though exactly why this date was chosen remains unclear
- Its counterpart: the year's first festival day, on January 24th, is called "Hatsu Atago" and draws large numbers of worshippers
Why So Many "Closing" Observances at Year's End?
December 24th also coincides with "Osame no Jizo," the final observance of the monthly Jizo festival days (also held on days containing the number 4). The custom of treating the year's final festival day as something special — calling it "shimai" or "osame" — reflects a shared cultural thread found at shrines and temples across Japan: a deep respect for properly closing out the year.
