Kasagi Boulders: Granite on the Kizu River, a Short Walk from the Station | Japan Climbing Crags
Granite bouldering on the Kizu riverbed in Kasagi, Kyoto: 109 problems on ROCKTOPO (about 100 per CLIMBING-net), mostly 4-kyu to 1-kyu. Both sites list it as year-round, with CLIMBING-net warning that midwinter is harsh. It is a 5–10 minute walk from JR Kasagi Station on the Kansai Line; the boulders are free, but drivers park at the paid Kasagi Campground downstream.
