The Notsuke Peninsula connects to the Okhotsk Sea of Hokkaido, Doto. It is located in Shibetsu-gun Shibetsucho and Hokkaido Notsuke-gun Bekkaicho. The Notsuke Peninsula is Japan's biggest sand archipelago with its total length of 26km, containing only level marshlands and beaches. The Notsuke Bay was recognized as a Hokkaido Heritage Site in 2004, and in November of the following year the "Notsuke Peninsula and the Notsuke Bay" were registered into the Ramsar Convention. The Notsuke Peninsula, showing various expressions from season to season, has many sights to offer each season. One of the charms of the Notsuke Peninsula is that you can enjoy the sea and the flower fields at once. The whole archipelago is a primeval garden, and during Spring to Fall flowers such as black lilies and rugosa roses bloom everywhere. Though erosion is currently in progress, areas that used to house forests of Sakhalin firs and Mongolian oaks withered due to coastal erosion and subsidence in the land, and you will now be able to see whitened and desolate sceneries called "Todowara" and "Narawara" (also known as "World's Edge").

Its appearance of withered shrubberies covering its surface changes into an open field of Ice when the Notsuke Bay of the Peninsula interior crystalizes when the season turns into winter (Around January to the middle part of March). In recent years, this white open field surrounded by the sea is gaining attention not as an horizon but as an "Ice Horizon". On top of freezing up, snow also piles down on the snow roads that seem to go on forever, making it look it like it came from another country and not from Japan. The sight of the Notsuke Bay freezing and turning into a landmass of ice is such a beautiful scenery that it has even been called the "Uyuni" Salt Lake" of Japan. Atop such a scenery of the sea, the popularity of "Todowara Ice Horizon Walk Tour" is rising even in social media by taking trick photos using perspective techniques. You can enjoy the 360 degree panorama of the ice scenery while walking atop the crystalized Notskuke Bay with snowshoes for about 2 hours. From time to time, the guide will also suggest poses that can be easily shot, such as the "tiny person on top of my palm" trick. Why not make memories of your travels by taking many trick photo shots while enjoying a hullabloo? Along the way, if you are lucky, you might also encounter Ezosika deers and arctic foxes. *You cannot go to frozen surface without guides accompanying you.

Said to be a type of mirage created by a difference in the air's temperature, the "square sun" phenomen where the sun can appear as a square shape is also something to see. Based on your luck and timing, there might be a possibilty where you will be able to see a beautiful and phantom-like morning sun gradation.

At the Notsuke Peninsula Nature Center there are many reservation-style winter tours being distributed (January to March), such as the "Todowara Ice Horizon Walk Tour" and the "Ice Horizon Mini-Walk Tour". Also at Odaito, the opposite shore of the Notsuke Peninsula, you can fully enjoy Onsen hot springs baths and the bounties of the sea such as theJumbo Scallops only at Bekkai.
