The space between the gate pillars is posted with a tratape and this sign so that vehicles are not allowed to enter.
(Translated by machine.)

In the past, banners and homemade signs were posted, but there were problems such as not being able to take a place to post, being vulnerable to wind and rain, and taking time to post and create, but this one-touch mounting sign does not have these problems. Moreover, it is useful because it can be purchased at a low price.
