The following post is quite long, so please bear with me. While living in Japan, I was in three separate incidents that resulted in police involvement. In two cases, a Japanese man, both strangers, verbally and physically accosted me without provocation, and I responded in self defense. (I’m female.) No notable injuries were sustained on either side. In both cases, both parties were taken to a police station, fingerprinted, ID'ed, and questioned separately . I'll clarify here that no one was arrested. By the time the police arrived, we had stopped fighting and were waiting for them. The police asked if we would come to the station, and we agreed. During questioning, the police did not accuse me of breaking or violating any specific laws, although they scolded me a bit. Both cases concluded a couple of hours later with everyone agreeing to apologize to each other, after which we were free to leave. No charges were filed on either side, and there were no court summons, convictions, fines or incarcerations. Although the police wrote detailed reports for their records, which both parties had to sign, they didn't issue a written citation or any other kind of document. The third case involved a Japanese man who slammed into me with his bike while I was on a sidewalk, knocking me into the street. He ditched his bike and tried to run away, but I chased him down and cornered him (no physical contact), while I called the police. The police questioned us separately onsite, but no one was taken to the station or fingerprinted. ID's were checked and cleared. The man tried to blame me, but it was clear from the bloody scrapes on my leg that he was lying, so that was quickly debunked. The police asked if I wanted to press charges, and I told them, no, I just wanted him to be penalized according to the law. They issued him a written citation, and we went our separate ways. My questions are: - Would any of these incidents appear on my Japanese police record and/or show up in background checks, even though I wasn't charged or convicted? - If they are entered on my record, how would they be categorized? Would the police mark them as misconduct or violations (i.e. simple assault for the first two incidents)? I'd think (hope) they would have clearly informed me of this during questioning, but can't put confidence in assumptions. - Is there a way for me to look up my Japanese police record without going through bureaucracy?
