Although the broadcast of "Okaeri Mone" has ended, we will continue to update the weather quiz until February 2022! Until now, we have been updating the quiz by weaving in content from the drama, but from now on, we will be introducing various weather-related topics in the form of a quiz♪
Now, let's start the quiz!
There is a seasonal word for autumn called "Ko○biyori," but what word goes in the blank?
The correct answer is C, spring! It's called Koharubiyori. This is an autumn word, so we don't use it in spring.
From the end of autumn to the beginning of winter, it gets gradually colder as we approach winter. However, there are times when the weather suddenly becomes warm and sunny, like spring. This is called Indian summer.
Indian summer refers to the warm, calm, sunny weather that occurs from late autumn to early winter (from the end of autumn to the beginning of winter).

In the past (called the lunar calendar), the word "Koharu" was used to represent October. The old October was equivalent to late October to early December today. In other words, it was from the end of autumn to the beginning of winter. It's about this time of year.
And hiyori means "sky, clear skies, good weather." In other words, Koharubiyori means "good weather like spring."
However, winter is coming soon. The warm days like Indian summer are becoming fewer and fewer, and winter is fast approaching. Please take care of your health.
