Although Shodoshima is a peaceful island floating in the Seto Inland Sea far from Osaka, it once played a crucial role in Japanese history as a major source of stone for the construction of Osaka Castle’s massive walls. Known as the “Island of Stone,” Shodoshima supported one of the largest building projects of the early modern period. This tour traces that story through real locations and immersive experiences.

Your journey begins at a working stone quarry. Standing before exposed rock faces and partially cut stones, you can sense the moment when stone that has lain dormant for centuries is revealed to the air and shaped by human hands. The scale of the landscape conveys the immense effort required to extract these materials. Next, at Osaka Castle Stone Memorial Park, you will try traditional techniques used by stonemasons. Activities include splitting stone, pulling heavy stones using a wooden sled (shura-biki), and creating your own engraved stone piece using sandblasting. These experiences reveal the ingenuity, physical strength, and craftsmanship required to handle such massive materials.
