- Can you contact her mother?
- Do you know the company which she or her husband works at? You can call the company and ask.
- Does she or her husband have a Facebook account? (Many Japanese do.)
If you can find mutual friends on FB, you can contact them and ask for information.
- I got below information on the net. If you know someone in Japan, she/he can do this instead of you.
●Summary of steps to check whether someone is alive or not when he/she does not respond to your call in Japan.
(note: this artilce is mainly written for people who are living in Japan, not for foreign tourists.)
１．Contact his/her family, friends or work place to confirm whether other persons can contact him/her. He/she might be just ignoring only you if you have a trouble with him/her.
２．Judge whether it is emergency or not by checking SNS (such as posts suggesting suicide, illness, etc), or ask acquaintances about his/her recent situation (such as he went to climb a mountain, he was arrested, he was hospitalized, etc).
３．Visit his/her home if he/she does not respond to anyone and there are obvious problems such as he/she did not come to work place or school, and judge if it is emergency or not.
４．Call police according to degree of emergency. You can consult with police officers by calling #9110 if it is not emergency, or you can visit nearby police station to consult about the matter (athough Japanese police officers may not speak English or other foreing languages). You can also contact consltation offices for foreigners in Japan. The consultation offices are located in each municipal but the users may be limited to foreignors who are currently living or working in Japan, and reservation may be also reuired for preparing an interpreter.
You should call police by calling 110 if it is really very emergency and you need police officers to come as soon as possible. You should not call police if it is not really very emergency because police officers are very busy for dealing with emergency matters.
You should call Japan Coast Guard by calling 118 if a maritime accident has occured (police is also OK because the police officer contacts Japan Coast Guard anyway).
You should call Disaster Emergency Message Dial by calling 171 if a massive disaster happens such as earthquake and flood.
5．Ask police officers to come his/her house and then ask a locksmith or the landlord to open the door of his/her house if he/she might have died in the house, or it is highly possible that he/she can not respond or move due to severe illness or injury.
6．Visit nearby police office to write application to search for the missing person if he/she is not in the house and still missing. Police may call you later if he/she was found or found to be imprisoned.
