A medical school in the Japanese capital apologized Tuesday for altering the results of entrance exams to stop women from studying there.\r\nAn internal investigation found that Tokyo Medical University\u00a0started manipulating the results in 2006\u00a0- or possibly earlier -\u00a0because its leaders thought female students\u00a0would leave their careers when they became mothers.\r\nThe investigation found that last year, the school reduced all applicants\u2019 first-stage test scores by 20 percent, then added up to 20 points for male applicants. It said similar manipulations had been taking place for years.\r\nLawyers investigating the scandal said the university\u2019s former chairman and president each received money from parents of prospective students whose entrance exam results were \u201cpadded," Japan\u2019s Kyodo news agency reported.\r\nThe manipulation was revealed during an investigation into the alleged wrongful admission of a bureaucrat\u2019s son in exchange for favorable treatment for the school in a ministry project. The bureaucrat and the former head of the school have been charged with bribery.\r\nThe school said the manipulation was wrong\u00a0and would not happen again. It said\u00a0it would\u00a0consider retroactively admitting students who otherwise would have passed the exams, but did not explain how it would do so.\r\n\u201cWe sincerely apologize for the serious wrongdoing involving entrance exams that has caused concern and trouble for many people and betrayed the public\u2019s trust,\u201d said Tetsuo Yukioka, the school\u2019s managing director.\r\nHe denied any previous knowledge of the manipulation and said he was never involved.\r\n\u201cI suspect that there was a lack of sensitivity to the rules of modern society, in which women should not be treated differently because of their gender,\u201d he said.\r\n\u00a0\r\nYukioka said women were not treated differently once they were accepted, but acknowledged that some people believed women were not allowed to become surgeons.\r\nJapanese women are among the most educated in the world, with nearly 50 percent\u00a0having college degrees, but about 70 percent \u2013 according to media reports - leave their jobs after having children because working Japan\u2019s\u00a0long hours is no longer feasible, and a lack of adequate childcare. Women are also expected to do the majority of the housework and care for elderly relatives.\r\nMore than 55,000 Japanese children were waiting for kindergarten places this year, rising for the third straight year, the country\u2019s welfare ministry said. The government plans to increasing the childcare spaces by 320,000 by 2021, the Japan Times reported.\r\nEarlier this year, a Japanese woman was reprimanded by her boss for becoming pregnant\u00a0before it was her \u201cturn,\u201d\u00a0\u00a0going against a timetable that dictated when women employees were allowed to marry and have children. according to media reports.
