Daiōsaki Lighthouse

Daiōsaki Lighthouse is a white concrete structure perched on coastal cliffs where two seas meet in the Shima area. The tower rises prominently above the rocky terrain and offers views across the water where shipping routes have long passed through these channels.

The structure was built after a series of shipwrecks in these dangerous waters had highlighted the need for better navigation guidance. Construction took place in the late 1920s to improve safety for vessels passing through this critical maritime region.

The lighthouse attracts numerous artists who capture its stark white structure against the Pacific Ocean, making the area a significant destination for painters.

The site is easily accessible from surrounding areas and offers visitors a secure platform for viewing. The best time to visit is during clear weather when visibility across the water is at its maximum and conditions are most comfortable for exploring.

From the observation platform, visitors can watch an intriguing optical effect as ships approach the horizon and gradually come into full view. The way vessels appear first as a mast before the hull becomes visible naturally demonstrates the curve of the Earth in action.
