Maiko Park
Maiko Park opened in 1900 as the first prefectural park in Hyogo Prefecture. This park also serves as a gate for Akashi Kaikyo Bridge or “Pearl Bridge,” the world’s longest suspension bridge, attracting many tourists from Japan and abroad.
It's located right under the Akashi Kaikyo Bridge. There's also a Sun Yat-sen Memorial Hall, though I'm not sure how it's related. It's a nice place to enjoy views of the bridge and the sea.
