Due to increasing numbers of trespasses, Japan's "most terrifying ghost sites" have come under the limelight. Recent incidents involve thrill-seekers and paranormal enthusiasts illegally entering these culturally significant locations to explore and document their experiences. The authorities have tightened security and called for the public's respect for these sites, marking a considerable rise in such incidents in recent days.

Haunting tales and supernatural folklore are deeply rooted in Japanese culture. These locations are often viewed as vital touchstones of cultural heritage with a note of fear and respect. However, the increasing trend of trespassing has alarmed the authorities, film-makers, and paranormal explorers, whose activities may disrespect traditional beliefs and potentially violate preservation laws.

In the US or EU, urban exploration is also a popular pastime, including visiting abandoned and supposedly haunted locations. However, trespassing is generally illegal, and individuals caught doing so face appropriate consequences. In some cases, historic or supposedly haunted sites may offer guided tours, often sanctioned by local authorities or property owners, to provide a legal and safe way to experience these locations.
