First of all thanks for this TBS news , I am really happy .I have been in Japan for 13 years and I have two kids .I was a university teacher before come to Japan, and now I am a housewife. I think Japanese schools had a good education system. Every day when two kids come back from school, my question is to talk to them and ask them about the learning situation at school and the situation between their classmates. Also ask them what was the most interesting lesson in class today? Or ask them how much homework they have ? As a parent, no matter how busy you are,the most important thing is to take a time to talk and communication with your kids. Especially encourage your kids in learning .From all conversations, you will find out how is he doing at school? If you don't communicate with your kids , they will day by day hide their emotions, which is will eventually lead to bad things happening.
