Shima Blue Oku-Shima Lake Kayaking

Oku-Shima Lake, nestled deep within Shima Onsen, features a cobalt-blue lake surface created by nature known as 'Shima Blue'—a trending spot on social media. Joining a kayak tour lets you paddle at your own pace across the crystal-clear waters, exclusively embracing the spectacular 360-degree panorama of fresh greenery and autumn foliage. You'll be amazed by the transparency so pristine that the lake bottom is visible, and in the silence, you can gaze at the sky and mountains reflected on the water's surface—an extraordinary escape from the everyday. Combine it with a hot spring visit for a day of pure bliss.
