You will often hear “sa” at the end of a sentence together with “datte,” as in “dekaketeta nn datte sa” (I heard he/she has gone), “ashita yaru nn datte sa” （I heard he/she would do it tomorrow), and “dame nann datte sa” (I heard it was a no go). This expression is used to convey information you’ve heard from another person, or second-hand information. It sometimes implies the following: Distancing yourself “watashi ga itte iru no deha nai” (it’s not me that’s saying this). Discontent: “oshiete moraenakatta kara kommata” (the problem was that I wasn’t told). Surprise: “shitte bikkuri shita” (I was surprised to hear it). It makes a slightly rude impression, and is not used in formal situations. Though this is a masculine expression, particularly young people, and also women occasionally use it in casual situations, mostly with their contemporaries or juniors. It has several other meanings besides this. To conclude or to make orders: “kore ni kimatteru sa” (That decides it), and “soryaa, iku sa” (It’s a matter of course). It can imply a rebuke: “hennji mo shinai de nani sa” (I still haven’t received a reply), “sonnna koto itsu itta no sa” (when did I say so). Some small consolation: “kimi nara dekiru sa” (It’s okay. You can do it.), “kore de ii sa” (It’s fine as it is). In the previous examples, it is used in the same way as “yo.” However, these days neither men nor women tend to use “sa” as a substitute for “yo.”
