Its official name is 'Our Lady of the Lighthouse Abbey, Order of Cistercians of the Strict Observance.' In 1896 (Meiji 29), a total of nine monks from France, the Netherlands, Italy, and Canada visited this land, founded Japan's first Trappist monastery for men, and named it 'Our Lady of the Lighthouse Abbey'.

They focused on farming, stockbreeding, and dairy farming. In 1902 (Meiji 35), they imported Holstein breeding cattle from the Netherlands, and the dairy cows they propagated later spread throughout the southern Hokkaido region, centered around the monastery. After the war, as the Japanese diet improved, the butter and cookies made at the Trappist monastery became popular among the people and spread nationwide as a representative specialty of Hokkaido.

Trappist cookies and butter are beloved in the local area and are also famous as souvenirs. Additionally, products such as jams made from agricultural produce grown in the vast natural surroundings are also sold. At the Trappist Monastery shop, you can taste cookies and soft-serve ice cream made with Trappist butter.

The cherry trees planted at the Trappist Monastery are a late-blooming variety. They begin to bloom when all the famous cherry blossom spots in the city have finished. Varieties such as Naden, Fugenzo, and Amayadori cherry trees bloom here.
