Occult Boom Day

What Is Occult Boom Day?

Every July 13th is "Occult Day" (オカルト記念日, Okaruto Kinenbi) in Japan. On July 13, 1974, the American horror film "The Exorcist" (エクソシスト, Ekusoshisuto, directed by William Friedkin, 1973) was released in Japan — triggering what Japanese media described as an "occult boom" (オカルトブーム) as audiences experienced the film's unprecedented supernatural horror content and sought out further occult-themed entertainment, books, and media. The Exorcist's Japanese release sparked widespread public interest in demonic possession, paranormal phenomena, and supernatural horror that reshaped Japanese popular culture.

The Exorcist's Impact on Japan

The Exorcist was already a global phenomenon when it reached Japan in 1974, having terrified and fascinated American audiences since its December 1973 release. Its Japanese reception was equally intense — the film's graphic depiction of demonic possession and exorcism was unlike anything Japanese audiences had encountered in domestic or foreign cinema, and its box office success was matched by a wave of occult-themed books, television programs, and cultural phenomena. Japanese publishers rushed to produce books on supernatural phenomena, UFOs, Nostradamus, and mysterious powers — content that found enormous appetite among readers excited by the possibilities the film suggested.

Japanese Horror's International Success

The occult boom that The Exorcist triggered in Japan eventually contributed to the development of Japan's own distinctive horror tradition — J-horror (Jホラー) — which produced internationally acclaimed films including "Ringu" (リング, The Ring, 1998) and "Ju-On" (呪怨, The Grudge, 2002). These Japanese horror films, with their distinctive imagery of pale, hair-obscured ghosts, supernatural curses transmitted through media, and atmosphere of inexplicable dread, reversed the cultural flow — influencing Western horror in return.

Fun Facts

• Nostradamus boom: One consequence of the Japanese occult boom triggered by The Exorcist was an extraordinary public interest in Nostradamus — the 16th-century French astrologer whose cryptic quatrains were interpreted as predicting various future events. Japan's "Nostradamus boom" (ノストラダムスブーム) of the 1970s-1990s was arguably the most intense in any country, generating enormous publishing volume and genuine public anxiety about the predicted 1999 apocalypse.
• Spiritual healers: The occult boom also contributed to the growth of new religious movements and "spiritual healing" practices in Japan — a trend that intersected with existing new religious traditions and occasionally produced exploitation of vulnerable people seeking supernatural assistance.
