The famed hot spring Kawayu Onsen draws its waters from MtAtosanupuri, a name that means “naked mountain” in the Ainu language. True to its name, the mountain’s slopes lack trees, and steam billows from vents with a thunderous roar, creating a dramatic sight. Getting as close as possible to view the fumaroles adds to the sense of occasion.

Here we introduce Mt. Io (Atosanupuri), a designated natural sightseeing feature of Teshikagacho.

硫黄山（アトサヌプリ）～日本一近づける噴気孔観賞～｜弟子屈を楽しむ｜弟子屈なび｜北海道弟子屈町

名湯「川湯温泉」の湯の源である「アトサヌプリ」は、アイヌ語で「裸の山」を意味します。その名の通り、山肌は木々が生えておらず、そこかしこからゴウゴウと音を立てながら噴煙が上がり、その数は1000以上ともいわれ、周囲には硫黄の独特の匂いが立ち込めています。地元では長年「硫黄山」の名でも親しまれており、噴気口を目の前で観賞できることから、訪れた観光客をそのダイナミックさで常に驚かせています。かつては硫黄採掘で栄えたこの山は、採掘した硫黄を運び出すために敷設された鉄道を通して、弟子屈の町の発展の礎を築いた場所でもあります。2023年に改装リニューアルした硫黄山MOKMOKベースの展示にて、往時の様子を知ることができます。駐車場からは、砂礫を歩いて噴気孔のすぐそばまで近づくことができます。ダイナミックな地球の鼓動をぜひ体感してみてください。なお、アトサヌプリの噴気孔及び硫黄結晶は弟子屈町の「特定自然観光資源」に指定され、山のほとんどはエコツーリズム推進法に基づく立ち入り制限区域に指定されています。貴重な資源を踏み抜くことのないよう、ご注意ください。 ※アトサヌプリを登り、この貴重な自然美を楽しむ「アトサヌプリトレッキングツアー」は、弟子屈町の認定ガイドにより特別に立ち入りが許可されています。
