The Defense Ministry will continue to provide a balanced education at its Joint Staff College, but will not immediately respond to criticism that some of its lecturers are known to hold nationalistic views, Vice Defense Minister Kohei Masuda said Thursday.

Sessions at an Upper House committee last week revealed that sacked Air Self-Defense Force Chief of Staff Gen. Toshio Tamogami, ousted for justifying Japan's wartime aggression in an essay, had launched lecture courses on wartime history during his stint as head of the JSC.

The names of the course's tutors, including those of hardcore hawks such as Atsushi Fukuchi of the Atarashii Kyokasho o Tsukuru Kai (Japanese Society for Textbook Reform), had been concealed by the Defense Ministry until Wednesday night.
