How much personal information does a private investigator need to identify someone?
This content is machine-translated.
For example, if you only give them your LINE ID or email address, are there cases where they still can’t track you down?
This is assuming you’ve also taken precautions to make sure you can’t be followed on the way home.
I’ll answer this as Maezawa from the president’s office.
I think it depends on the detective agency’s capabilities. If they’re good at what they do, they can probably tail someone without being noticed.
Apparently, there’s a rule of thumb in this field: “You need at least seven people and three cars to conduct a proper tail.” If they follow that faithfully, they could probably tail you without you realizing it.
But if they try to cut costs and do it with just two or three people, you might notice you’re being followed—and if you do, you may be able to shake them off.
Normally, it seems unlikely they could identify someone through LINE or email alone. However, if they can get the provider to disclose the person’s IP address information, they could probably track down the individual.
Figuring out how to get that information disclosed—which providers generally won’t do—is probably where the detective agency’s expertise comes in.

You’re absolutely right, Marika.
Depending on the detective agency’s capabilities and how much you’re willing to pay, it’s safest to assume that there’s basically nothing they can’t find out.
For example, they may even go through the subject’s discarded trash. You can’t just throw things away carelessly.
As for “taking precautions so you won’t be followed,” Joe thinks that would be extremely difficult, considering how skilled they are at surveillance.

I’ve never used a private investigator myself, but…
Judging from the websites of private investigation agencies, it seems they can even track down a boyfriend who has blocked you on LINE, depending on how much you’re willing to pay.
Email addresses would probably be easier to investigate since you already know the address.
As far as someone’s identity is concerned, it’s probably safest to assume that if they have any information to go on, they can find out just about everything.
Above all, it’s best not to do anything that would make people hold a serious grudge against you.

That sounds like you’ve been through some scary experiences…
Poor thing…
There have been several times when women have given me their addresses, but even when they asked me to come over, I wouldn’t even go as far as their front door.
The most important thing in papa-katsu (compensated dating in Japan) is making the woman feel safe and at ease.
Even with people you’re close to, basic courtesy still matters.

It’s really not something an amateur could hide.
For certain reasons, I was once followed by a private investigator. They tracked my movements perfectly all day without me noticing in the slightest. I don’t know how many days it went on.
It wasn’t about catching me in an affair or anything like that, but it was genuinely creepy.
I think they could find out everything—from your family and workplace to your official family register. I suppose it depends on how much you’re willing to pay.
