This is a typical description of many Japanese high school students who lack the skills to communicate and interact with others.

The increasing number of such students has prompted a Fukuoka high school to introduce a new compulsory subject, Japanese Communication, aimed at encouraging students to talk more.

Since its launch in April at Fukusho High School in Fukuoka's Minami Ward, the subject has generated much interest among educators.
