The former lens is now on display at the museum at Daiōzaki Lighthouse in Mie Prefecture.
Noma Lighthouse in popular superstition was held to be a place that jinxed romance.
However, there is a belief that if a couple attaches a padlock to the fence surrounding this lighthouse, their love will prosper.
In the year 2000, Mihama Town declared the area around the lighthouse to be a park, and the Koinomizu Shrine (恋の水神社, Koinomizu Jinja) established a small branch near the fence to receive the padlocks instead.
In October 2011, the Nihon Fukushi University, also based in Mihama, set up a railing, designed as a musical score, as a place to also affix the padlocks.
