Shin-Matsudo 4-chome Neighborhood Association Bulletin Board (Shin-Matsudo 294-2)
(35.8298683, 139.9141791)
Matsudo City, Chiba Prefecture

Emily got permission from JR East to install a neighborhood association bulletin board on a freight rail fence, but it was denied. JR East is not on private land, and when we inquired with Matsudo City, they said that it is definitely the bulletin board in Shin-Matsudo 4-Chome. How should we make this decision?
