     Brick structure designed by R.H. Brunton. The Shiriya Saki Lighthouse is in an area known as the birthplace of fog signals, with the fog bell being the first fog signal in Japan.

     This is also the birthplace of electric lighthouses with the first being the electrification of the lighthouse with arc lights in December of 1901. Since this optical device was modeled after the Eckmille Lighthouse of France, it was called the elard type electric arc lamp. With this improvement, light intensity increased from 36,000 cd to 13,000,000 cd to the extent that its brightness was referred to as the "sun of the sea".

     However, because of the high cost of the equipment and the troublesome care required, arc lights disappeared with the exception of the domestic Kamishima Lighthouse in Mie prefecture.

     Preservation repairs together with the earthquake reinforcements were implemented in 1983.
