When talking about autumn in Japan, the terms momiji and koyo are often used interchangeably. However, they actually have different meanings.
So, what exactly is the difference between momiji and koyo?
The Difference Between Momiji and Koyo in Japanese

Although both terms are associated with Japan's autumn foliage, momiji and koyo do not mean the same thing.
Momiji generally refers to the Japanese maple tree and its vibrant red leaves that change color during autumn. In everyday conversation, Japanese people also use the word momiji to describe the iconic red maple leaves that symbolize the fall season.
Koyo, on the other hand, refers to the natural phenomenon of leaves changing color in autumn.

The term includes all types of trees whose leaves turn red, yellow, or orange during the season, including maple, ginkgo, zelkova, and many others.
In short, momiji refers to a specific type of tree and its leaves, while koyo refers to the seasonal phenomenon of autumn foliage.
