Hachishaku follows Chado-san, a monk returning to the recently abandoned village of NaniNani Mura to investigate his childhood exile to Tokyo, the vanished residents, and a friend he remembers fondly. A legendary spirit stalks him as he searches for answers, tying the village’s mystery to a struggle to escape its grasp.
Play centers on exploring the village and piecing together its past through villagers’ journals, notes, and photographic evidence. Alongside that investigation, Chado-san must find five sacred jizo and return them to their shrines. The game also lets players collect money for costumes, accessories, and hairstyles for the towering stalker, an unusual customization thread woven into its horror setting.
The description names three possible outcomes: escape the village, be spirited away, or confront Chado-san’s duty. Hachishaku is listed as single-player, so its format is a solitary investigation rather than a shared multiplayer pursuit. The announced launch selection includes costumes, hairstyles, accessories, and hats; a peaceful Gravure Mode in Hachishaku’s secret hideout is described as a planned update, not as a confirmed current feature.
