Kokushi Island

Finished

黒祠の島

Non-fiction writer Katsuragi Shiho visits her friend Shikibu Takeru in Tokyo and hands him the key to her apartment, asking him to take care of her belongings if she doesn't return from a trip in three days. When she fails to come back, Takeru grows worried and begins investigating. He discovers that Shiho was last seen boarding a ferry to Kokushi Island, a remote and isolated place off the coast of Kumamoto.

On the island, Takeru finds a community steeped in ancient traditions and strange religious practices. Bizarre occurrences soon surface: a naked female corpse hanging upside down from a tree, unexplained deaths, and a pervasive silence among the locals. As more bodies are found, Takeru must navigate a web of superstition and secrecy to uncover what really happened to his friend.
