海之宇宙館 / Umi-no Uchuu Kan

海之宇宙館（位於羽幌町天売島）裏面有攝影家寺沢孝毅作為館長的免費展示設施。除了可以取得被稱作海鳥樂園的天売島的資訊之外，也可以欣賞到海鳥和風景的美麗照片。也有咖啡廳區塊和商店。環島一週約3小時的散步之後推薦這裡為最適合的休息場所。1999年6月開幕的。

Umi-no Uchuu Kan (Teuri Island on Haboro Town) is a gallery which is free to enter. The owner is Mr. Takaki Terasawa, a local nature photographer. Here, visitors can get a range of information on Teuri Island, which is also called ‘a heaven for seabirds.’ Beautiful photos of both the island and its seabirds are also proudly displayed. Facilities include a shop and cafe. An adult can walk around the island in approximately three hours, so this facility is a good spot to take a rest. Umi-no Uchuu Kan opened in June, 1999. The name stands for the house to feel how sea is deep and huge like the cosmos.
