Traduko - Japana-Angla - 明日があるさ

Romanized:
Ashita ga aru sa
Literally:
Tomorrow exists, hey
Notes:
The "sa" kind of works like a "Hey" in English.
The meaning of this is: "Well, don't worry about whatever you're worrying about, because you'll be able to fix it/do it/make up for it tomorrow."
"Hey, (don't worry,) there's (always) tomorrow (to do what you need to do)."
