What does 神 Kami mean?

Kami is translated as god, and the translation is the problem. The Japanese word covers a range of beings and presences so wide that the English term, shaped by centuries of monotheism, cannot hold it.

What the word actually admits

Deities with names and stories. The spirit of a particular mountain, river or waterfall. Ancestors. Historical figures enshrined after death. Objects and places that provoke awe. The category is defined by the response a thing commands rather than by what it is, which makes it closer in structure to yokai than to anything in English theology.

A common phrase counts them in the eight millions, a figure meant as countlessness rather than as arithmetic. The plural is the normal case, which is precisely where English god starts to strain.

Why god is the wrong size

English god arrives with a definite article and a capital letter attached, carrying omnipotence, creation, moral authority and singularity. Applied to the spirit of a waterfall, it is comically oversized. Applied to a named deity in a myth cycle, it is roughly right. The same word cannot do both jobs without misleading half the time.

The consequence shows up in compounds. A death spirit becomes a god of death, which sounds cosmic and singular, when the Japanese is closer to a spirit associated with dying. Translation inflates the term and then readers reason from the inflated version.

The slang, which is the best evidence

Modern Japanese prefixes the character to nouns to mean excellent: a god episode, god art, a god move. It is casual, it is common among younger speakers, and it is not blasphemous, which tells you something exact about the word's weight.

English cannot do this comfortably. Calling a television episode godlike reads as either hyperbole or irreverence, because the English word does not have the room. The Japanese usage is closer to saying something is outstanding, and nobody flinches.

Why the mismatch is structural

English religious vocabulary was built for a tradition with one god and a sharp line between divine and not. Japanese vocabulary developed where that line is a gradient and where a thing can become worthy of reverence by age, by beauty, by strangeness, or by having been important to people.

So there is no single English word available, and there is no shape of hole to point at either: the hole is the whole gradient. Keeping the Japanese word is the only rendering that does not decide the question in advance.
