Osaka's northern bay area along the Yodo River mouth, where the historic water transport routes connecting Kyoto and Osaka Bay converge, was once the city's most vital commercial waterway district, and the Sakurajima area adjacent to Universal Studios Japan continues the tradition of entertainment and commercial energy in one of Osaka's most dynamic urban bay districts. Osaka Sakurajima Onsen draws on sodium and bicarbonate thermal waters from deep geological wells beneath the Osaka bay plain, offering restorative baths in the Sakurajima waterfront area of northern Osaka where Universal Studios Japan, the Osaka Expoland site, and the bay water scenery create an entertainingly active spa setting within reach of the city's northern bay attractions. The Universal Studios Japan theme park with its international entertainment attractions, the Osaka Bay area cycling and walking paths along the reclaimed waterfront, and the views across Osaka Bay toward the Kansai International Airport island create an accessibly vibrant and bay-facing spa destination in northern Osaka.
