The salt warehouses belonging to the former Ministry of Finance’s Ako Salt Affairs Bureau (which later became the Japan Monopoly Corporation’s Ako Branch) were built in Meiji 41 (1908), the same year the Salt Affairs Bureau building was completed. In the past, the salt that was produced in salt farms was carried here on uwanibune, small boats used to ferry cargo, and was transported into the warehouses on carts. Today, parts of the tracks these carts left behind still remain on the bridge that crosses the Shin River. The warehouses were massive single-story wooden buildings with pantile gable roofs and horizontal plank walls on the exterior and a single large earthen-floored room on the interior. There used to be ten warehouses arranged into two rows, with one row to the north and the other row to the south. Seven warehouses remain today and serve as things such as the Ako Folk Culture Museum’s repository, a public employment agency for elderly people, and warehouses for salt producers. The warehouses give a sense of what the former Monopoly Corporation was like.
