Insider tip — In Ibaraki city, the northern Osaka satellite city home to Expo City retail complex and the historical Ibaraki Kasuga Shrine, Neboke Onsen (drowsy/half-asleep spring) offers pleasantly soporific mineral bathing in a playfully named facility; the sodium-chloride dark waters from the Osaka Bay sedimentary aquifer are genuinely conducive to the drowsy relaxation the name promises.
