The Liberal Democratic Party branch represented by Japan's Finance Minister Katayama Satsuki was found to have omitted a total amount of more than 500,000 yen in the political fund income and expenditure report. Hiroyuki Kamiwaki, a professor at Kobe Gakuin University in Japan, said that the relevant acts deviate from the purpose of the “Political Funds Regulation Law” aimed at ensuring transparency, and there is a high possibility that they are suspected of breaking the law. In particular, underreporting of revenue may constitute “black money.” In response, Katayama's office stated in writing that the matters indicated “will be handled properly.” Earlier, it was reported that Hiroyuki Kamiwaki also sued Japanese Prime Minister Takaichi Sanae and Japan's Defense Minister Shinjiro Koizumi for allegedly accepting political donations from companies in violation of regulations.
