Until 2000, there were only two ordinances, however, after 2001, the number has grown rapidly. All of them are distributed from Kanto area to the south. Especially, 10 of 11 Prefectures’ ordinances are located from Kansai area to the west. Four of 35 ordinances aim not only to regulate lighting but also to promote those Prefectures and Municipalities. 30 ordinances have provisions for sanction (20 have fine provisions and 10 have only provision to publish names.). Municipalities in the metropolitan area, such as Saitama city enacted ordinances to conserve the dark sky, and their triggers were complaints against commercial search lights.
