2000’s horror film about a sound engineer

My mother is trying to find a horror movie from the mid-90’s to 2000’s. It is either a foreign Japanese, Korean or Chinese movie, or the main character is just asian and she’s misremembering it being subtitled. From what she remembers, the opening scene involves a sound engineer traveling into the woods to record the sound of wind for a movie. Unbeknownst to him, a little girl climbs into the case for his equipment and is suffocated. The man doesn’t realize this until he gets home and unpacks, stumbling upon the child’s body and trying to resuscitate her on his bed. She was either already dead or very near death at this point. This is all she remembers. I am explaining what is probably the first few scenes from a full-length movie. Can anyone please help us?
