Discover Kashni Waterfall in Shiretoko, a UNESCO World Heritage Site, a remote and breathtaking natural wonder accessible only by sea.

Named after an Ainu word meaning “a place with a temporary hut,” Kashni Waterfall stands as an iconic landmark on the Shiretoko Peninsula. Fed by pristine streams originating from Mt. Shiretoko, the waterfall plunges about 30 meters down sheer, rugged cliffs before flowing directly into the Sea of Okhotsk.

Its striking formation combines a powerful vertical drop with intricate tiered cascades, set against the dramatic backdrop of a massive sea cave. The ever-changing flow creates a captivating scene that never fails to impress. Surrounded by untouched primeval forest and completely inaccessible by land, this remote location offers a rare blend of deep tranquility and raw natural power.

One of the best ways to experience this remarkable sight is by sightseeing cruise departing from Utoro Port. From the deck, visitors can feel the sea breeze while watching the waterfall up close. The roar of water crashing against the cliffs and the vivid contrast of white cascades against the deep blue sea create an unforgettable view. Visible only from the open sea, this extraordinary landscape is one of the highlights of Shiretoko, leaving a lasting impression on all who witness it.
