Super Sento Akane Onsen is located in Takamatsu, Kagawa Prefecture, Shikoku, Japan. Its sodium-chloride thermal water reaches 40°C. An indoor bath, an outdoor rotenburo and a sauna are offered.
Insider tip — Takamatsu is gateway to Shikoku and home to Ritsurin Koen — one of Japan's three finest traditional landscape gardens (16 ha, 300 years of refinement, six ponds and thirteen hills). Kagawa Prefecture is Japan's udon heartland: Sanuki udon noodles (thick, chewy, served in subtly sweet dashi broth) are a regional obsession with over 600 udon restaurants. Enjoy a udon breakfast at a local mill, explore Ritsurin, then unwind at Akane Onsen (akane = madder red, a natural dye plant) before ferrying across the Seto Inland Sea.
