If a teacher tries to interfere, the students try to stop the teacher by exerting physical force such as hitting or kicking, especially in the case of female teachers. Instead, they put their faces out the classroom window and continue talking among themselves. Only a few students were seated in their seats to listen to the teacher. In another school, a teacher has reported that some kids had cut a classmate's school bag with a knife into small pieces or had thrown somebody else's bag into the fire to burn. Another elementary school teacher reported that nobody talked and responded to her questions during her class.
Nobody sings with the teacher during the music class.
During the lunch time, nobody eats what the teacher has helped to serve. There seems to be no statistics kept on these cases. According to a female teacher who teaches in a medium-sized city in the western part of Japan, there are at least one or two classes in each elementary school where teachers could not run the class as they would have liked. Not only did she point out how common the problem was among the fifth and sixth graders, she went on to say that in recent years in some schools similar problems were found among the first graders as well. She said that among the very young students like the first graders, the intention of destroying the class was not evident.
