Iwaki Island is known as the "Island of Blue Lemons," where the cultivation of lemons and other citrus fruits is thriving, and shipbuilding has become a foundational industry of the island. In spring, over three thousand cherry blossom trees bloom magnificently on Mount Sekizen, which towers about 370 meters in elevation at the center of the island, making it famous as one of the top cherry blossom viewing spots in the country. Additionally, due to its historical significance as a key maritime route, the island served as the main headquarters for the Iyo Matsuyama Domain during the feudal era, reflecting a rich history of prosperity as a critical hub for maritime transportation.
