In the vicinity of Saijo Inari Shrine in Okayama City, it's difficult to deliver the New Year's postcards on New Year's Day due to the numbers of visitors to the shrine, and therefore the nengajo have been delivered on the previous day, New Year's Eve, since 1978 (according to "NHK News").
岡山市の最上稲荷近辺では年明けに参道が参拝客で混雑して配達できないため、1978年より1日繰り上げて大晦日（12月31日）に年賀状を配達する（『NHKニュース』より）。
