In Japanese folklore, water spirits are often personified as yokai or kami, including figures like kappa and ikuchi. Kappa are mischievous creatures associated with rivers and ponds, known for their ability to drag unwary individuals underwater. In contrast, kami are revered spirits embodying elements of nature. These water spirits highlight the significance of water in life, serving as both protectors and healers but also representing potential danger, reflecting the dual nature of water as both a source of life and a potential threat.
