The JDM bumpers kouki and zenki, do they share the same REAR brackets, are they the same brackets, can I use the same REAR brackets with the jdm kouki or zenki bumpers?

Zenki, Kouki, Trueno, Levin, etc..... the brackets are all different.

For the front there are 4 types of brackets, Zenki and Kouki for the Levin and Zenki and Kouki for the Trueno.

For the rear there are 2 types of brackets, Zenki and Kouki. Levin and Trueno are the same.
