Nishimatsu Construction Co.'s former president, Mikio Kunisawa, pleaded guilty Tuesday to purchasing fundraising party tickets for a Liberal Democratic Party faction led by Minister of Economy, Trade and Industry Toshihiro Nikai.

At his second Tokyo District Court trial session, Kunisawa, 70, admitted violating the Political Funds Control Law by using Nishimatsu's dummy organizations to buy fundraising party tickets for the Nikai faction's political body, Atarashii Nami, on two occasions in June and July 2006 worth a total of ¥3.4 million.

Kunisawa has already pleaded guilty to giving ¥5 million in illicit donations through the dummy firms to the political fund management body of former Democratic Party of Japan President Ichiro Ozawa and to bringing into Japan ¥70 million from the firm's overseas slush fund without reporting it to customs authorities between February 2006 and August 2007.
