Ryugasaki, in southern Ibaraki Prefecture, is a growing suburban city between Tokyo and Mito whose traditional Kanto plain agricultural landscape has been preserved amid suburban development, maintaining rice paddies and vegetable farming in the fertile volcanic loam soils of the Kashima lowlands east of the Joso railway corridor. Ryugasaki Onsen Ibaraki draws on sodium and bicarbonate thermal waters from the geological resources of the southern Ibaraki lowlands, providing warm restorative baths in a suburban community whose agricultural setting, convenient location on the Tokyo-Mito transport corridor, and the traditional Ibaraki food culture of natto, dried sweet potatoes, and fresh lake fish create an accessible and unpretentious spa setting. The Ryugasaki City Air Base with occasional aviation events, the traditional Ibaraki natto fermented soybean culture, and the cycling routes through the flat Kanto plain rice paddies of southern Ibaraki create a straightforwardly pleasant rural and suburban spa destination.
