Last night was chushu no meigetsu. This is what they call they call a full moon in the middle of an autumnal month.
Awhile back, I wrote a detailed post about jugoya, and while researching for this post, it seems that it means the same thing as chushu-no-meigetsu...the harvest moon.
We once visited Shimogamo Shrine in Kyoto while they were celebrating the Harvest Moon which I wrote about here.
Don't forget to eat some tsukimi dango while gazing at the moon.
