Ganbare, international students!
Sun-Net was born in 1989 as a telephone operator offering land line connection to student dorms. When the Internet came into our lives, we adapted to the market in order to offer the best service. A few years ago we released our own SIM card service to solve the common problems faced by international students, universities and Japanese language schools’ staff.
Due to our proven experience we can offer you an excellent customer service, so you can spend your time on what really matters, enjoying your daily life in Japan!
We also want to know your opinion about our services in order to improve them and help more students!
