Oiwa Shrine / Oiwa Inari (Seki no To) — Yotsuya Kaidan sites

Oiwa is the female figure at the center of the classic kabuki and folk ghost story Yotsuya Kaidan, a tale of betrayal, murder and the emergence of an onryō (vengeful spirit). The story and its characters figure prominently in Japanese performing-arts scholarship and popular culture. Several modern references name a shrine dedicated to the spirit of Oiwa (rendered as Oiwa Shrine or Oiwa Inari Tamiya Shrine), and the shrine-name is used in kabuki-related promotion and performance contexts. Sources differ on the shrine's physical locus: the Yotsuya Kaidan tale is traditionally associated with Yotsuya in Tokyo, while a Wikidata entry lists an Oiwa Shrine in Kyoto Prefecture. The provided materials do not give precise coordinates, founding dates, or detailed site-history for a specific standing shrine, nor do they supply first-hand contemporary accounts of paranormal activity at a physical shrine site. Culturally, the association of a shrine dedicated to Oiwa indicates the tale's transition from theatrical/folkloric narrative into devotional and commemorative practice; in other words, the literary onryō of Yotsuya Kaidan is represented in Shinto shrine form in modern references and promotional contexts for kabuki performances.
