You said it, not me

Something about this made me smile. Anyway, its a good example of how to use 自分 correctly.

日本人は自分の国の文化をユニークだと思いっている。
The Japanese think that their country's culture is unique.

自分= じぶん= "a reflexive pronoun that refers back to a human subject with whom the speaker is emphasizing" (-A Dictionary of Basic Japanese Grammar)
