Origin and Etymology
“Heaven high horse fattens autumn” is a proverb that originates from Chinese classical literature. Originally, it was an expression found in Chinese poetry and prose, used as words that expressed the beauty and abundance of the autumn season.
This expression is thought to have been transmitted to Japan from the Heian period to the Kamakura period, when the influence of Chinese literature was strong. The intellectuals of Japan at that time studied Chinese poetry and prose, and incorporated their beautiful expressions into Japanese literature and everyday language.
“Heaven high” represents autumn’s crystal-clear blue sky, and “horse fattens” means that horses become fat due to autumn’s abundant harvest. In ancient China, horses were important property, and fat horses were also a symbol of prosperity. Also, autumn was the harvest season, and it was a time when livestock could get sufficient nutrition due to the abundance of grain.
In Japan, this proverb became connected with the culture of appreciating seasonal changes, and became established as words expressing autumn’s beauty and abundance. Especially in times when agriculture was central, it was beloved and used as a familiar and approachable expression that allowed people to feel the joy of harvest and the blessings of nature.
Usage Examples
- Today was truly a pleasant day that felt like “Heaven high horse fattens autumn”
- They say “Heaven high horse fattens autumn,” but when this season comes, my appetite increases every year
Modern Interpretation
In modern society, changes can be seen in the meaning of “Heaven high horse fattens autumn.” Originally it was a seasonal expression representing autumn’s natural beauty and abundance, but in modern times it has come to be used more often with the interpretation of “autumn of appetite.”
Particularly, the “horse fattens” part tends to be understood in connection with human appetite and weight gain. Not a few people use it with the meaning “in autumn, food is delicious and you gain weight.” This can be said to be an interpretation connected with modern abundant food culture and the culture of enjoying seasonal ingredients.
Also, in urban areas, there are almost no opportunities to see horses, so the original meaning of this proverb has become difficult to relate to. Instead, as words expressing autumn’s refreshing climate, attention often focuses mainly on the “heaven high” part.
However, in recent years, interest in returning to nature and lifestyles that value seasonal feelings are being reconsidered. On social media, posts using this proverb along with photos of autumn’s beautiful sky can be seen, and the value as words expressing original seasonal feelings is being re-recognized. Even in modern times, it continues to have new meaning as words that teach the importance of noticing seasonal changes in busy daily life and feeling the beauty of nature.
When AI Hears This
The reason why the meaning of “Ten takaku uma koyuru aki” (High skies and fat horses in autumn) has changed 180 degrees over time lies in the dramatic transformation of Japanese living conditions.
In ancient China, autumn was a season that determined life and death. This was because for the nomadic horsemen of the Mongolian plateau, horses that had grown fat during summer became their ultimate military force. Riding horses that had built up strength through the grass-rich summer months, they would head south to target agricultural regions abundant with food during harvest season. In other words, “autumn when horses grew fat” was a “signal that war was beginning.”
However, in Japan, due to the geographical condition of being an island nation, there was no direct experience of threats from nomadic horsemen. Therefore, when this proverb was introduced to Japan, the military tension disappeared entirely, and it was accepted purely as an expression describing the beauty of the season.
What modern Japanese people envision when they hear this proverb is a scene of blue skies and abundant harvest. Yet originally, it meant “be on guard, the enemy is coming.”
This transformation can be seen as a典型example of the “semantic bleaching phenomenon” that occurs when language moves across cultures. Words severed from dangerous realities are reborn as beautiful expressions. This is truly a fascinating case where a peaceful environment changed even the meaning of words themselves.
Lessons for Today
