Recently, captivating images of a luminous spectacle in the night sky above Tottori, Japan, sparked a flurry of speculation across social media platforms.
Initially believed by many to be a cosmic or extraterrestrial occurrence, these images depicted nine pillars of light radiating across the skyline.
According to a report by Mothership, the phenomenon observed in Tottori on May 11th has been identified as a well-known occurrence in Japan called ‘Isaribi Kochu.’
‘Isaribi Kochu’ translates to “fish-attracting light pillars.” These mesmerizing lights are not of extraterrestrial origin but are rather a result of practical fishing techniques employed by local fishermen.
The initial photographs capturing the luminous pillars were shared on social media by a user named Maashii, who witnessed the spectacle above the coastal town of Daisen.
Another user named totoro8201 posted a similar image, claiming to have seen the light pillars from Nariishi beach, approximately 12 kilometers east of Daisen.
Contrary to the cosmic theories circulating online, the reality behind these luminous pillars is grounded in the age-old practice of squid fishing.
Japanese fishermen utilize specialized lights known as “Isaribi” to attract larger catches. These lights create a visually striking effect, particularly under specific atmospheric conditions.
The phenomenon occurs when overnight temperatures drop sufficiently, leading to the formation of ice crystals in the atmosphere above the fishing vessels. These ice crystals reflect the light emitted by the fishermen’s boats, creating the radiant pillars.
During cooler overnight temperatures, crystals may occasionally develop in the atmosphere above these illuminated fishing boats. Under specific conditions where significant crystals form without any precipitation, the light beams can manifest as a result of the boats’ illumination reflecting off these crystals.
