how do immigrants find guarantors in japan?

ami are you trying to find a guarantor for an apartment contract I assume?

There are a few ways foreigners in Japan get guarantors (at least for housing).

1. Their employer acts as a guarantor, also depends on the contract the person has with the company they work for. If you are a student, some universities will also act as a guarantor but it depends on the school.

2. They know someone in Japan and that person is of enough status to act as their guarantor.

3. Absent of an actual person, some foreigners employ a guarantor company. However such companies can be quite expensive sometimes.

Minus any of those points, it takes time to develop contacts in Japan before someone can find a guarantor, since being someone guarantor is a bit of a responsibility for someone to take on.

It is really, really hard. Basically, you have to know a Japanese person well enough that they trust you enough to sign for you. That means if you don't pay your rent, they'll step up for you. The only real way to do this is if you have family or a very, very close friend in Japan before you move there. Your company can also be your guarantor, but they usually will only do this for specific apartments they already have arranged. Otherwise, you're stuck renting from someone who's willing to rent to gaikokujin without a guarantor, so you're looking at lower quality housing or a house (like the one I lived in) that passes from foreigner to foreigner without much interference from the Japanese landlord, who's more than happy as long as somebody pays the rent.

A lot of the duties that a guarantor are supposedly necessary for a judicial scrivener can and will do if they are paid for their time. You don't necessarily need an attorney in Japan, but a good scrivener can help out a lot for not a lot of money. I'm not suggesting a scrivener can solve all your problems but I sent sent my guy to the immigration office with my paper for re-entry permits, renewals, etc., etc. instead of taking time off my job for years and it was all good.

There's no way a bengoshi would lower themselves to such mundane crap no matter how much one was paying. The reality is that any given judicial scrivener can cook up papers so complicated that they won't want to meet said scrivener's bengoshi buddy or the client in question.

Japan doesn't take open immigrant policy.

Are you talking about the personal guarantors for your student Visa?

I am hearing that some students from Asian countries are using their parent's connection with Japanese (usually their daddys are rich) or school exchange programs (between Japanese Univ and the college in your country).

i didn't even know japan allowed immigration.
