This question already has an answer here:
I saw this answer for how the nuance changes between the use of passive and intransitive verbs when the verb is negative. I was wondering what the difference is with a positive verb. Here's an example:
Both of which, I hope, mean "the wallet was found". Is there a difference, or would you just not bother with the passive if an equivalent intransitive verb exists?
Response to duplicate suggestion: I have looked at Passive-transitive-verb vs. Intransitive-verb （他動詞の受け身 vs. 自動詞) but found the answer difficult to follow. In particular I thought example 3 was supposed to be with an intransitive verb but it still seems to be taking an object.
