Foreigners Locked for 24 Hours at Osaka Immigration Facility -- Jiji Press

Maltreatment of foreign detainees by Japanese Immigration Bureau has been one of the latest exposure that collects public attention in Japan. This is another example.

In this case, taken place at the Osaka Immigration Bureau, 17 detainees were locked up for 24 hours in a room with capacity of 6 people. According to the article, the reason of locking them up is: detainees refused to leave the six-person room even though they were told to go back to their own rooms after their free time ended. What I see as the problem is the comment made by the bureau, according to the article, as: the measure of locking them up in the room was appropriate.
becuase of  "to keep order" after their belligerent acts, such as jeering.

Room capacity is generally set by the safety concern to prevent the physical danger of ones stay inside. If they locked up numbers of humans in a room almost 3 times of the capacity, for the considerable length of 24 hours, and they say it as an appropriate measure...., it means that they do not secure the safety of detainees in the facility. Here, we see the bureau lacks a safety management in the facility, and they seem not to be mindful about such lacking.

 If the detainees' act or attitude troubled the bureau officers, they have to make measures to 1) cease the act and attitude under their guideline (I wonder if they have one though, and if so, the problem goes bigger) then 2) make the detainees return back to where they were. If the bureau does not have a resource for doing 1) and 2), they shouldn't let 17 detainees gathered in one place. Here we see the bureau lacks a risk management of when the situation becomes beyond their capacity to handle.

Also, in this case, locking up the detainee seems the penalty assessed by the officers personally. But the officers do not have an authority to do so. Here, we see the officers' sense of the authority is distorted.

The bureau officers need trainings of logical, systematical, and efficient skill in safety and risk management, so they will not need to make any self-made penalty with their distorted sense of authority.

The last thing to add: during the detainees being locked up in the room, a magnitude 6.5 earthquake hit Osaka area.
