Mitsuo Kaiji, a famous Japanese jewelry designer, was born in a jewelry family. His parents are engaged in jewelry creation, and I hope he can inherit the family business wholeheartedly. Although Mitsuo Kaiji's wish is to become a pop singer, in order to keep his promise to his parents, he resolutely ended his singing career for just five years, and went back to the jewelry industry from the music scene, spending ten years studying jewelry and designing his own brand jewelry. After decades of continuous efforts, Mitsuo Kaiji now has not only its own jewelry store, but also a professional gem appraisal qualification.
