Unbelievable! Japanese fisherman finds 15-year-old letter in the belly of a caught fish

A 52-year-old Japanese fisherman found a letter and fragments of a red balloon in a fish captured from 1,000 meters deep in the Pacific Ocean. The handwriting on the letter was recognizable, and it was written by a 6-year-old girl who released it inside a balloon during her school's anniversary celebration 15 years ago. The letter also included the school's address. The little girl is now a college student.
