Built in 1877 at the tip of the old Sakai Port, the Old Sakai Lighthouse is 11.3m tall. It is one of the oldest Western-style wooden lighthouses still standing in the area. It was built when lighthouses were constructed all over the country to ensure the safe navigation of foreign ships after the opening of Japan following the arrival of Commodore Perry. Sakai carpenter Daibi Sataro was involved in the construction, and the lamp was designed by British engineer Biggleston. The construction costs were covered by donations from local residents. Initially, kerosene lamps were used, and it is said that the greenish light reached far out to sea. However, as the coastal area was reclaimed, it ceased to function in 1968. It was designated a national historic site in 1972. It has now been restored and preserved, restoring it to its former appearance.
