浩三
"浩三" (Kōzō) is a Japanese male given name, typically without a standalone meaning, as meanings depend on kanji context and interpretation.

浩三は公園で散歩をしています。
Kozo is taking a walk in the park.
In this usage, "浩三" is again a proper noun and is directly introduced as someone's name in the sentence.

His name is Kozo.
Here, "浩三" is used as a proper noun with the honorific "さん" to address a person respectfully by their name.
