The University of Tokyo has found that at least 43 research papers contains falsifications and fabrications, local media reported Thursday.
Those papers were supervised by Shigeaki Kato, a former professor of the top Japanese university. According to an interim in-house report, 43 of 165 papers supervised by him from 1996 to 2011 should be retracted.
Kato has admitted to Kyodo News that what the university has found is true.
"I couldn't recognize those who were making mistake. It's all my fault," he said.
Kato led a big research project which received 1.8 billion yen (about 17.94 million U.S. dollars) of taxpayer money from 2004 to 2009. But the project's main thesis also contained falsifications and fabrications, said the report, recommending that the thesis should be retracted too.
