ね and よ as Final Particles
ね as a final particle
The particle ね commonly appears at the end of a sentence in rising intonation. Its common purpose is to request an expression of agreement towards one’s own statement. Conversely, it can also be used to express that you agree with the preceding statement by evoking somewhat of a rhetorical tone.
Ashita wa shiken desune. (Tomorrow is the test, isn’t it?)
Iidesune. (That’s nice, isn’t it?)
Soudesune. (That’s right, isn’t it?)
よ as final particle
よ is used at the end of a sentence to proclaim new information.
Doko demo konbini o mitsukeraremasendeshita (I couldn’t find a convenience store anywhere.)
Jitsuwa, konbini ga asoko ga aru yo. (Actually, there’s one right there.)
よ is most commonly used in formal speech, as it can on occasion make the speaker seem assertive with the continual stream of new information.
