Cape Puyuni juts out into the vast Sea of Okhotsk, a little northwest of the Utoro district, the base of Shiretoko tourism. The meaning of "place with a hole" in Ainu language is said to refer to a sea cave that once existed here. The cape can be viewed from Utoro fishing port, but cannot be visited directly. The most representative spot of the cape is the observatory on a hill a little to the south. The sunset from here is reputed to be beautiful and is one of the "Eight Views of Shiretoko.
Shiretoko is a mountainous peninsula jutting out from the southern tip of the Sea of Okhotsk. The pristine nature here is home to a wide variety of animals, including brown bears, red foxes, whales, Steller's sea lions, Steller's sea eagles, and Blakiston's fish owls. The Shiretoko mountain range bisects the peninsula, with Rausu in the east and Utoro in the west serving as a base for travel. Visitors can fully enjoy the charms of this magnificent natural environment by driving around the numerous waterfalls, lakes, and capes, taking a cruise to view the peninsula from the sea, or taking an eco-tour to observe rare species.
