Cannot phone myoruji (ninja) temple in Kanazawa

Was wondering if someone could help me, I’m trying to make a reservation for the ninja temple in Kanazawa as I understand it is popular. I cannot get through on the phone though, despite purchasing international credits. There is no other way to contact them, wondering if anyone has any advice or knows someone in Kanazawa who could contact them on my behalf?
