Tsukuba, in the southern Ibaraki Prefecture, is Japan's premier planned science city, established in the 1960s to concentrate the nation's leading research institutions including the High Energy Accelerator Research Organisation, the National Aeronautics and Space Administration's Japanese partner JAXA's Tsukuba Space Centre, and over 300 research institutes making Tsukuba one of the most research-intensive cities on earth. Tsukuba Onsen Ibaraki draws on chloride-rich thermal waters from the geological formations of the Tsukuba volcanic zone beneath the Kanto plain, offering restorative baths in a city where Nobel laureates in physics and chemistry continue cutting-edge research alongside traditional Kanto agriculture in the unusual juxtaposition of high science and rural Japan. The Tsukuba Space Centre's rocket and satellite exhibitions, the Mt. Tsukuba twin-peak hiking and cable car ascent to panoramic Kanto plain views, and the Tsukuba Expo Centre's science museum create a uniquely intellectually stimulating backdrop for thermal spa relaxation in this remarkable science city of southern Ibaraki Prefecture.
