Aika Momma is a financial adviser at Nikko Cordial Securities Inc. with a renewable one-year contract and he -- along with a growing number of young professionals -- is happy with his situation.

The 24-year-old Momma had a chance to become a permanent employee at a housing company after graduating from university two years ago, but chose the job of financial adviser at the Yokohama branch. He did not have to relocate, but his salary is based on job performance.

If his performance does not measure up to company expectations, his contract will not be renewed.
