Former head of the National Tax Agency Nobuhisa Sagawa (front) appears as a sworn witness in the Diet, Japan's bicameral legislature, in Tokyo, Japan, March 27, 2018. A key figure in a document-tampering scandal involving Japan's Finance Ministry appeared in the Diet on Tuesday to give sworn testimony over the falsification of government documents related to the heavily discounted sale of state land to a nationalist school operator. Former national tax agency head Nobuhisa Sagawa, who was previously in charge of taking care of the land sale, stepped down to take account for the confusion he had caused and was under fire for potentially lying in parliament while serving as director general of the ministry's Financial Bureau.
