In this supernatural thriller from Japan, Hinako (Yui Natsukawa) is a young woman with a successful career as a fashion designer who pays a visit to the village on the island of Shikoku where she grew up. Hinako learns that her best friend from childhood, Sayori (Chiaki Kuriyama), the daughter of the villages spiritual leader, died in a mysterious drowning accident. She also discovers that another childhood friend, Fumiya (Michitaka Tsutsui), is still living on the island, and as they renew their friendship Hinako finds herself sexually attracted to Fumiya. Theyre both startled when Sayoris spirit begins appearing to them, and they begin researching Shikoku folklore; they discover that the island is believed to be the gateway to another world, and Sayoris mother is trying to open the path so her daughter can return to this realm. Shikoku marked a change of pace for director Shunichi Nagasaki, who previously made the romantic drama Some Kinda Love. ~ Mark Deming, All Movie Guide
