Nagoya University (NU) has recently received many complaints about phone calls regarding the introduction of private tutors from a person claiming to be an NU student.
NU itself does not have any official student associations that introduce private tutors. NU students who wish to work as a part-time private tutor register with the NU Cooperative Union (CO-OP) at the University, and receive services related to private tutor jobs from the NU CO-OP.
Most calls such as this could be fake calls from someone claiming to be an NU student, so please be duly cautious.
