On her 40th anniversary a Dutch windmill called De Liefde (Dutch for The Love) has been erected by the Dutch millwright company "Verbij Hoogmade BV" near the south-eastern shore of Lake Imba as a landmark of the Sakura Furusato Square. The mill serving as a polder mill is named after the first Dutch sailing ship which landed on the Japanese shore in 1600. For safety reasons against earthquakes the mill-tower is made of concrete and covered with brick-looking tiles (half-stones). The mill's sail-cross diameter amounts to 27.5 metres (90 ft). It's the only windmill of that type in Japan (a so-called "ground-sailer", which means a windmill whose sails reach almost down to the ground which the canvas sails are set from.).
