Japanese adverbs similar to English ones?

Sorry yet again, but I'm still confused about adverbs.

Are Japanese adverbs exactly the same as English ones (manner, place, time, reason, frequency)?

No one really is answering the question:

Are Japanese adverbs made by prepositions, verbs, nouns, or a different part of speech that is not in English?

Like, a noun can describe manner (The fast walk). if this is the case, then why do adverbs have there own category, similar to English?

Like, if were to read a Japanese grammar book written in Japanese, there would not be an adverb category, but something else does the job for adverbs.
