The present invention pertains to a system for managing management area users, the purpose of the present invention being to manage the clothing of users after entry into a managed area. The present invention comprises an input device (200) for reading an ID of a user (600). The clothing of users who enter a managed area for which a dress code is determined is managed. A post-entry video of a user who has entered the managed area is acquired by an imaging device (300). An ID and the post-entry video are linked using a user identification unit (410). A clothing assessment unit (420) assessment whether the user (600) has met the dress code on the basis of the post-entry video. A right-to-pass-setting unit (430) makes an association with the ID of users who have not met the dress code, and disallows the right to “pass on subsequent occasion” within a user database (440). A passage device (500) prohibits entry of users for which “pass on subsequent occasion” has been disallowed.
