Climate

Although cold for its latitude and coastal position, the humid continental climate (Köppen Dfb) of Hiroo is moderated by East Asian standards. Summers are cooled by the ocean and cloudy weather, whereas the influence of the Siberian landmass drops temperatures in winter. Due to the ice-free nature of the ocean, Hiroo stays narrowly above freezing during days, whereas nights regularly drop beneath −10 °C (14 °F).

History

The area flourished from the Jomon period. A settlement of Ainu people existed along the southeast Hiroo River. It was part of Matsumae Domain in the Edo period and was on a road opened by the Tokugawa shogunate along the coast to Kushiro. It was the site of a jin'ya established to govern the entire Tokachi Province. During the Bakumatsu period in 1858, it was awarded to Sendai Domain, which relocated farmers, carpenters, and woodsmen to the area and began cultivating grain and vegetables. In 1906, the village of Moyori was established under the second-class town and village system. Its name was changed to Hiroo Village in 1926, and was elevated to town status in 1946.[5]

The 2011 Tohoku earthquake and tsunami resulted in a 2.8m tsunami striking Hiroo, causing over 1 billion yen in damage.[5]
