Production stops in 1990's and maintenance and spare parts ran out in 2011 forcing this siren in Yawatahama using custom parts to make it running and if it break down then bye bye lol as it cannot be fixed anymore. It got broken down in 2018 for making custom replacement/spare parts but now its still active today SO GO TO JAPAN NOW TO SEE THE MUSICAL STUFF WHILE YOU CAN :D Songs that played by this siren: 6.00am=八幡浜漁港の唄(Song of Yawatahama Fishing port) 12.00pm= みかんの花咲く丘(Hill of Tangerine blossoms) 18.00pm=夕焼け小焼け(Sunset light glow)
