Shiraoka, in the southern Saitama Prefecture along the Tone River approaches, is an agricultural community known for its traditional Saitama strawberry cultivation — the early-season Tochiotome and Akihime varieties grown in the warm southern Saitama lowlands reaching market in winter thanks to the heated greenhouse technology that has made Saitama one of Japan's most significant strawberry-producing prefectures. Shiraoka Onsen Saitama draws on sodium and bicarbonate thermal waters from the geological resources of the southern Saitama lowlands, providing restorative baths in a strawberry-cultivating agricultural community whose seasonal berry picking experiences, traditional Kanto plain farmhouse landscape, and convenient access to the Tokyo metropolitan area and the Tobu Isesaki Line create an accessible and pleasantly agricultural spa setting. The Shiraoka strawberry farm picking experiences from December through May, the Saitama Prefecture traditional daikon radish and Chinese vegetable farming of the surrounding plain, and the easy access to the Kasukabe and Koshigaya shopping and cultural centres make Shiraoka a pleasantly seasonal and agricultural spa destination.
