As the news of the Finance Ministry's document-tampering continued to send shock waves throughout the nation, a throng of irate protesters gathered near the Diet building Tuesday evening for the second day in a row, calling on Prime Minister Shinzo Abe and Finance Minister Taro Aso to immediately resign.

The protest followed a similar rally staged in front of Abe's headquarters the previous night, when hundreds were seen chanting "Tell the truth!" and "Abe must quit!." On Monday, the participants occupied a huge part of the street near the Prime Minister's Office amid a heavy security presence.

"People who seem incapable of complying with the law are in there," 61-year-old Shigekazu Ishihara said, pointing his finger in the direction of the Diet.
