This is, I think, a quirk of the Japanese language. It famously has many of what we would consider first person pronouns, which have a feeling to me of kinda being third person themselves. Or maybe it would be more accurate to say they don't have such a strict delineation. Occasionally one can even hear someone use, for example, 'boku' as a second person pronoun. It's maybe kinda like in a casino a dealer might say that "the house" wins, or a judge might say "this court" regarding a decision. Only many such 'role' pronouns exist in Japanese.

One can imagine growing up as a child and hearing Japanese with its variety of first-person pronouns, which also are not used as much as we use them in English, and choosing to use your name as it is consistently associated with you.

That said, I've had only a smattering of Japanese study, so definitely take all of that with a grain of salt.
