In some religions, Sanretsu (attendance) and Shoko for funerals conducted in other religions are prohibited, and so some funerals are conducted without religious ceremony considering the different religious background possibly existing among the surviving members of the family and those present.
宗教によっては、異なる宗旨で行なわれる葬儀への参列や焼香などを禁じているものも存在するため、遺族や参列者に異なる宗教的背景がある場合、それらに配慮して無宗教という方法で葬儀を行なう場合もある。
