　September 13 tonight is August 15 in old calendar, and the mid-autumn moon (fifteen nights). It is also called "Imo Meigetsu" because of the custom of offering taro that has reached the harvest season. This time is considered to be the best season to love the moon, with the moon rising at an angle suitable to just look up in the clear night sky, but the city center on this day is a bad cloudy sky. But sometimes the clouds broke out, and the moon came out. The "moon floating in the waves of clouds" is also tasteful. Even in the old days, the fact that the moon is hidden by clouds or the like on a mid-autumn night is called "no moon", and the rain is called "rain moon", and I heard that he enjoyed the subtle atmosphere.

From the Sumida River Terrace, you can see and hide the moon above the window lights of the skyscrapers in Tsukishima and Kachidoki. By the way, since the phases of the moon are not perfect one month, the mid-autumn moon (15 nights) is not necessarily the full moon, and this year the next 14th is the full moon. This year marks the 50th anniversary of the landing of Apollo 11 on the moon, when humanity first descended on the moon. I think again about the physical, cultural and historical aspects.
