My bpd ex girlfriend says that she’s going to kill herself or just come to my house and kill me if I don’t meet with her( Japan)

Honestly I’m scared to meet with her and she might even kill herself if I don’t. I’m 100% sure she will hurt me if I meet her. In the scenario that she kills herself do I bear any responsibility legally? I have never encouraged her to do this and told her to stop that and live her life every time she mentioned suicide. She knows where I live and said that she’s going to stab me if I don’t meet with her, but if I meet with her she’s going to hurt me anyway. I’m a foreigner living in Japan
