Beppu City Onsen Supply, Kannawa Line 70 wellheadOperated by · 別府市
A sodium chloride spring drawn from Beppu City's Kannawa supply network. The salty, heat-retaining chloride water sits at the centre of the local bathing tradition; the public posting lists it simply as a chloride spring, and Sujiyu serves it as free-flowing, undiluted source water with no recirculation or dilution.
