A consumer advocacy group representing applicants who allege they have been subject to unfair admissions practices filed a lawsuit against Tokyo Medical University on Monday with the Tokyo District Court, the first legal action in a series of scandals embroiling Japanese medical schools.

A government probe has found similar misconduct at multiple institutions.

The nonprofit Consumers Organization of Japan is demanding that test fees and associated costs be paid back to affected applicants, including men who took the test multiple times and women. The group said it decided to take legal action after being frustrated by what it describes as the university's slow response.
