Hepburn Romanization - interjections
 

Friends,
I guess native speakers don't like romanization a lot, but I would like to know if japanese interjections obey modified Hepburn (revised Hepburn - second variant).
I never used it on interjections coz I don't know the source of them.
Could you give me an accurate explanation about the theme?
そうさ夢だけは...
Is there any syllabic division in this "sousa" (interjection "Yes, that's right"...)?
"Sou-sa"? "so-u-sa"?
I have the sensation the pronounce is "sou - sa" [sôsa?]
Or the correct is Don't use romanization with japanese words no-derived from kanjis?

Thank you very much.
If here isn't the right place, please move the thread.

Anything in Japanese only obeys the rules of whatever romanization you've chosen. But if you choose a romanization, apply it uniformly. Your question doesn't really make any sense.

But if you're asking if Japanese people use Hepburn romanization, no, they don't. Everyone in Japan is taught kunrei-shiki in school in elementary school. Kunrei-shiki is very different from Hepburn.

Sorry, my friend.
I know about that, Kunrei is pretty good too (and alike too).
It makes sense for me because I use it.
I wait for a direct, correct and useful clue about romanization of interjections using modified Hepburn because I must to be coherent with my previous translations (all under modified Hepburn [revised Hepburn-second variant] rules).
Anyway, thank you very much for your participation.
