Hihi (Japan)

Hihi are large, ape-like yokai with lips so massive that they can completely cover their eyes when they laugh. Their name, hihi, comes from the sound they make while laughing. For reasons unknown, hihi find humans amusing and burst into laughter—“hihihi”—whenever they encounter one. These yokai dwell in forests and mountains, preying primarily on large forest animals. However, if given the opportunity, they will not hesitate to hunt and devour humans.
