As structures made of brick are weak against earthquakes, the lighthouse was completely destroyed by the earthquake that occurred on April 26, 1922. The reconstruction of the lighthouse as a reinforced concrete structure was completed on March 15, 1923. However, the new lighthouse functioned for only six months before again being damaged by the Great Kantō earthquake of September 1, 1923 (magnitude 7.9), the lighthouse was fractured with cracks and the top collapsed. Restoration work on the lighthouse was commenced on September 18, 1924 and, on June 1, 1925, the present Kannonzaki Lighthouse was completed.
