The Defense Ministry was hit again Wednesday by another apparent data cover-up scandal involving Defense Minister Tomomi Inada, prompting opposition lawmakers to further step up their calls for her immediate resignation.

On Tuesday, it was reported that anonymous government sources had said that Inada attended a Feb. 15 meeting of top ministry and Self-Defense Force officials where a decision was made to cover up the existence of daily activity logs pertaining to SDF operations in South Sudan that were said to have been discarded.

The revelation, if true, is scandalous because Inada has repeatedly claimed in public that she knew nothing of the cover-up decision within the ministry.
