Entrepreneur Misa Matsuzaki likes a good business challenge. The youngest female entrepreneur to publicly list a company on the Tokyo Stock Exchange aims to solve Japan's labor shortfall through increased migration.

Firms struggle to fill vacant jobs due to a chronic labor shortage caused by the nation's shrinking working-age population. There are 1.5 vacancies for every job applicant. The labor pinch will only intensify as the working population plummets in future years.
