The "beach" is a misnomer—what spreads before you is a geology lesson in stone. Basalt and andesite boulders, some the size of compact cars, crowd the shore in arrangements that shift slightly with each winter storm. Between them, smaller cobbles fill the gaps, polished smooth by wave action and clicking together musically as the surf withdraws. The few patches of coarse sand that accumulate in sheltered pockets are black with eroded volcanic minerals.
“The exposed volcanic bedrock creates extensive tide pool ecosystems rarely found on sand-dominant coastlines in the region.”

Tide pools form in depressions worn into the bedrock platforms, their still water revealing ecosystems in miniature: hermit crabs investigating crevices, sea anemones contracting at shadows, small rockfish darting between kelp fronds. The pools are warmest in late summer, their shallow water heated by the sun to temperatures that encourage longer observation. You'll need to time visits with the tide tables—high water covers most of the interesting formations, while the lowest tides expose rocks usually submerged.
The coast curves in a gentle arc here, offering views north toward the more dramatic cliffs of Sasagawanagare and south toward the Murakami port facilities. Salt spray has pruned the pines along the shore into twisted shapes that lean inland, their bark encrusted with lichen. The rock surfaces near the high-tide line wear coats of green and brown algae, slippery enough to require careful foot placement. Local kids know which boulders make the best perches for watching storms roll in.
