What does 木漏れ日 Komorebi mean?

Komorebi (木漏れ日) means sunlight filtering through trees' leaves. It names a particular kind of light; an English phrase can describe it without losing the phenomenon.

What the dictionary actually says

Kanjipedia's entry defines 木漏れ日 as sunlight coming through the leaves of thick trees. The writing combines 木, tree, 漏れ, leaking, and 日, sun or sunlight. The joined sound is komorebi; a character-by-character English gloss is not itself the translation.

The definition describes where the light passes. It does not specify a mood, a season or an emotion that every occurrence must express. Quiet pleasure may be part of a scene showing that light, but it is something the scene adds rather than a compulsory component of the noun.

Dappled light is useful but broader

Collins defines dappled in terms of patches of light and shade or markings. That helps describe the appearance. It is broader than komorebi: a dappled horse has markings, and the adjective alone does not require trees or sunlight.

Sunlight filtering through leaves is therefore a more explicit translation than dappled alone. Dappled sunlight through the trees can also work when the pattern matters. The choice depends on which feature the sentence is describing, rather than on finding one English word that must substitute in every context.

A compact noun does not prove exclusive perception

The existence of the Japanese compound cannot establish that English speakers fail to notice this light. The English phrase identifies the same source and route. Conversely, the availability of a translation does not make the Japanese word useless: a compact noun can be convenient and can have a particular sound in a sentence.

The correction is modest. A word's form and the experience it names are separate things. Comparing forms can explain a translation choice; it cannot rank entire populations by sensitivity to nature.

What an animated image adds

An animated shot can show moving leaves, uneven light and someone stopping beneath a tree. Those details may support a reading of rest or memory in that particular scene. Without an identified shot, however, claiming that this effect is a defining habit of all anime would be an unsupported generalization.

The noun identifies the light. The work's framing and timing establish what that light does in the story. Keeping those questions separate makes both the translation and the interpretation easier to assess.
