Has the recent Sino-Japanese relationship affected the travel to Japan?

I'd better not go My friend has studied, worked and lived in Japan for many years and recently returned to China. Because many young people in Japan don't have any jobs and many excellent China people work there, these young people in Japan are influenced by some anti-China sentiments. Now they are more and more dissatisfied with China people and often fight. My friend was very worried that his children would be affected and hurt, so he went back to China to rest for a while and then decided whether to continue living there.
