Nanatsugama Limestone Cave

Visitors typically prepare by wearing comfortable sneakers and bringing a light jacket to adapt to the cave’s cool environment. Many include the cave visit as part of a driving route through Saikai City. From the green landscape above ground to the distinct rocky scenery below, the site provides a setting where visitors experience a quiet passage of time away from daily life.
