Tobikoshi Quarry Site and Omi Remnants
(Osaka Castle Stone Remnants Park)
From the quarry that operated here, the Hosokawa clan shipped stones that would be used in the rebuilding of Osaka Castle. There are two large blocks from the time, engraved with a code number and the quarry’s triangle mark.
In the Meiji era the remnant stones were placed along the Omi wharf. Most of them were moved to this park when it was created in 1999. The stones show the skills of the Edo period masons, and there is a building with exhibits of stonecutting tools and information about the Osaka Castle walls.
