Hitachi Onsen Ibaraki is located in Hitachi City on the Pacific coast of northern Ibaraki Prefecture, a city that takes its name and identity from the Hitachi Corporation — one of Japan's largest technology conglomerates, founded here in 1910 in the copper mining and industrial complex that transformed this Pacific coast town from a fishing village into a major centre of electrical engineering and manufacturing. The chloride-rich coastal hot spring waters draw from the geothermal resources of the Hitachi coastal uplift zone, where the tectonic collision between the Pacific and North American plates has generated both the industrial copper deposits that gave rise to the city and the geothermal heat that feeds its hot springs, connecting industrial and therapeutic heritage through the same geological forces. Hitachi's spectacular Kamine Park and the Hitachi Seaside Park's extraordinary nemophila (baby blue eyes) flower fields that carpet the park's hills in electric blue each spring — one of Japan's most extraordinary seasonal floral spectacles — provide the natural counterpoint to the city's industrial identity and the therapeutic warmth of its coastal mineral waters.
