Translating '記憶がよみがえる' directly would yield 'Memories Revive' or 'Memories Return', but there's more nuance to unpack. The verb 'よみがえる' carries connotations of resurrection or rebirth, often used for things returning from oblivion. In anime like 'Your Name', we see this concept visually represented when characters recover lost fragments of their past.
When localizing for English audiences, 'Memories Reawaken' might better capture the emotional weight. It suggests dormant memories stirring back to life, much like how 'Ghost in the Shell' handles cognitive themes. The title could shift slightly depending on context - a psychological drama might use 'Memories Resurface', while a fantasy could opt for 'Memories Rekindled' to imply magical elements.
