What is 「所属機関」, "Attached Organization"?
There are two types of visa in Japan, "activities visa" & "resident visa".
An "activities visa" should be permitted in accordance with the activities in Japan such as the job. A "resident visa" should be permitted in accordance with the family relation such as the spouse.
Many of the activities visas are "working visas".
The objective jobs of working visas are usually to be done with some companies or organizations.
Immigration Control & Refugee Recognition Act defines a company or an organization which shall be worked with a "working visa" holder, as「本邦の公私の機関」to be translated into "public or private organization in Japan".
In order to apply for obtaining, changing or extending a working visa of a job with a "public or private organization in Japan", it shall be required not only a signature of the applicant but also a seal of the "public or private organization in Japan".
In the regulated application forms prepared by the ministry of justice, a company or an organization which shall be worked with is called as「所属機関」to be translated into "attached organization".
All of working visas are not required to have "attached organizations".
An "artist visa" or an "entertainer visa" can be obtained without an "attached organization" .
However it is principally necessary to put a seal of an "attached organization", if you apply for obtaining changing or extending any type of working visa on a job with an "attached organization".
In other words, you need to get an approval or a consent of the "attached organization" before apply for obtaining changing or extending a working visa on a job with an "attached organization".

there are differences of required documents or materials to be submitted in accordance with a category of the "attached organization".
