Nature Sites / Okinoshima Town
Above the beautiful white surface of the rhyolite rocks grow a number of plants representative of the Oki Islands, flowers that color the coast through the seasons. These include the endemic Oki rhododendron (Rhododendron japonoheptamerum var. okiense), the continental seashore spatulate aster (Aster spathulifolius), the southern Yeddo hawthorn (Rhaphiolepis umbellata), the subalpine oriental chive (Allium schoenoprasum var. orientale), and others. You can also see obsidian on the coast, which was used by the people of the Oki Islands to make stone tools as early as 30 thousand years ago.
