Hario Radio Towers

Three concrete towers soar near the Saikai Bridge. These towers are reported to have relayed the “Niitakayama Nobore 1208” ciphertext for the attack on Pearl Harbor that sparked the outbreak of the Pacific War. The 136-meter-high tower, which stands at the apex of the equilateral triangle with a side of 300 meters, was built in four years starting in 1918.
