Horai Bridge is an agricultural bridge built in 1879 (Meiji 12) to clear the Makinohara Plateau. Before the bridge was built, you had to cross the Oi River by small boat.
It was dangerous to go back and forth.
It is still used by farmers in the old city to manage the tea plantation on the opposite bank. In addition to playing an important role as a farm road, the Horai Bridge is a historic land improvement facility.
