大化け (obake: big changing in the literal meaning): it's often the case that obake generally means phenomena whose size and effect have increased; Ancient Shinto, which is connected with Japanese folk belief, has a concept of value by which it is thought that the higher ranking divine spirits reside in bigger things, such as himorogi (temporarily erected sacred space or altar used as a locus of worship) and iwakura (dwelling place of a god, usually in reference to a large rock): a tree which has grown to a greater extent than others or a rock which is larger than others can be a house of (bakeru [change to]) the divine spirit.
