Aya Ohzeki was still just a 17-year-old high school student when she founded her necktie company.

"A company will go down if it fails to earn money, so it's important to try to keep creating something special and unique that no one else can copy," the 21-year-old president of Noble Apex Inc. said.

Ohzeki, born in 1992, had wanted to start a business since she was in elementary school.
