You cannot fight it. Hold your breath and hide while the silkworm-woman hunts the dark.
A first-person Japanese horror adventure set in Ichinose, a village deep in the 1980s Japanese mountains. You explore on foot, solve puzzles, and scavenge scarce resources, all while a monster, a silkworm-woman, hunts the dark, and you cannot fight her: survival is hiding and slipping past. The story is a sisters' tale of love and hatred, drawn from a real folktale of Ibaraki Prefecture about the origin of silk farming, the legend of the Golden Princess, wrapped in silkworm-and-cocoon imagery, and it carries four branching endings and three difficulty levels. Made by NAYUTA STUDIO, a two-person Tokyo doujin circle, in the lineage of Fatal Frame. It already supports English, yet the West has only partly found it.

01First, the one feeling
- The monster cannot be killed, so the design takes your weapon away and leaves you only your breath: when the silkworm-woman is near, the whole game narrows to reading her path through the dark, choosing the one moment to move, and holding still while she passes, so the dread sits on patience and nerve rather than aim.
- Survival runs on what you can find, so every drawer you open and every room you step into in the first-person dark is a wager: the resources you need to go on are out there, but looking for them is exactly what exposes you, and the village is built so that curiosity and safety pull against each other.
- Underneath the fear is a myth, the real Ibaraki legend of silk's origin retold as a sisters' love-and-hatred drama in cocoon imagery, and with four branching endings across three difficulty levels, the pull is not just to survive the night but to learn which truth, and which ending, the village finally gives you.
02Who this is for (and who it is not)
For you
- You love Fatal Frame and the cursed-rural-Japan dread rooted in old folk belief, here a haunted 1980s mountain village steeped in a real Ibaraki folktale of silk's origin, the legend of the Golden Princess, told as a sisters' love-and-hatred drama
- You want exploration horror built on hiding, not fighting: scavenge scarce resources, solve puzzles, and slip past a silkworm-woman you cannot kill, in full first-person, across four branching endings and three difficulty levels
- You want a Japanese two-person doujin gem the West has only partly found, Very Positive at 92 percent over 906 reviews, that already supports English and many other languages
Not for you
- You want to fight back, with weapons or a camera you battle ghosts with; here the monster cannot be killed, and the whole loop is hiding and evading, not combat
- You are sensitive to heavy content, it carries depictions of violence, bloodshed, and suicide (though nothing sexual), or you expect a big, already-popular Western title; this is a 1,480-yen paid doujin work, fully released and not in Early Access, still largely Japanese- and Chinese-led abroad (about 21.7 percent of reviews are English)

Hollow Cocoon Buried gem
A first-person Japanese horror adventure set in Ichinose, a village deep in the 1980s Japanese mountains. You explore on foot, solve puzzles, and scavenge scarce resources, all while a monster, a silkworm-woman, hunts the dark, and you cannot fight her: survival is hiding and slipping past. The story is a sisters' tale of love and hatred, drawn from a real folktale of Ibaraki Prefecture about the origin of silk farming, the legend of the Golden Princess (Konjiki-hime), wrapped in silkworm-and-cocoon imagery. It carries four branching endings and three difficulty levels. Made by NAYUTA STUDIO, a two-person Tokyo doujin circle, the programmer UTUTUYA and the 3D-modeler KOZUE, and released in December 2023, fully launched and not in Early Access. Very Positive at 906 reviews and 92 percent. It is broadly localized, with English, Japanese (fully voiced), Simplified Chinese, Korean, German, and more, yet with 197 English reviews out of 906 (about 21.7 percent) the West has only partly found it; most of its audience is Japanese and Chinese. At 1,480 yen it is a paid, fully released game, not free, and the art is not AI-generated. It carries depictions of violence, bloodshed, and suicide, though nothing sexual.
Give it your first passFatal Frame The origin
The origin of the cursed-rural-Japan, folklore exploration horror: in 2001, Tecmo released Fatal Frame (titled Zero in Japan), a survival horror set in a cursed Japanese place where you confront the dead through a defensive camera, the Camera Obscura, with a sequel that moved to a cursed, lost village. It is fundamentally a third-person game, going first-person only when you raise the camera. It crystallized the skeleton of Japanese horror built on a remote, cursed place and old folk belief. Hollow Cocoon is a clear heir to that skeleton, a haunted 1980s mountain village steeped in a real silk-origin folktale, but it sharpens the view into full first-person, and where Fatal Frame fights spirits with a camera, Hollow Cocoon strips the weapon away entirely: you cannot fight the silkworm-woman, only hide and evade. There is no official Steam release of the 2001 game, so its origin is anchored to its Wikidata entry.
