There is still significant animosity towards Japan by several other Asian nations due to atrocities committed during WWII.

This is regularly triggered by various disputes about commonly claimed territory and things such as politicians visiting shrines that house the Japanese war dead (including war criminals). It often leads to rioting and destruction of perceived Japanese things (cars, restaurants, etc) in China.

Still no terrorist attacks in Japan committed by Chinese though despite Japan allowing in large numbers of Chinese visitors, students and workers.
