Pia 21 Shihoro (Shihoro Town) is a road station located at the intersection of route 241 and route 274. The road station was relocated to it's present site in April, 2017, following the construction of a new building. The motif of it's architectural design is a cattle barn. This is because Shihoro’s main industry is breeding cattle and agriculture. This road station focuses on local food, presenting a menu which showcases Shiroro Beef, which is one of the most famous beef brands in Hokkaido. Also, potato dishes such as fried potatoes are popular. Not only tourists but local people also frequent this road station to enjoy a meal.
