A low sun lifts off the water and the surface becomes a mirror that wants to be broken only by a paddle stroke. On Naiba Lake, just above Shionoe in Takamatsu, kayaks slide out from a small concrete launch and into the quiet held by a 70-year-old dam. The lake feels deliberate and slow: the breeze teases ripples, reeds lean like listeners, and the shoreline alternates between cedar stands and rocky berms.

A low sun lifts off the water and the surface becomes a mirror that wants to be broken only by a paddle stroke. On Naiba Lake, just above Shionoe in Takamatsu, kayaks slide out from a small concrete launch and into the quiet held by a 70-year-old dam. The lake feels deliberate and slow: the breeze teases ripples, reeds lean like listeners, and the shoreline alternates between cedar stands and rocky berms.
The dam that formed Naiba Lake was built in the postwar period to regulate streams and support local agriculture; the surrounding hills are folded volcanic and sedimentary slopes typical of northern Kagawa. Shionoe retains an onsen culture—expect steam rising from valley baths in cooler months and local farms supplying seasonal produce to nearby markets.
Practically, the tour is a gentle 2½-hour paddle designed for mixed groups and families. Equipment is provided, and guides will cover basic strokes, re-entry, and simple safety signals. Expect calm water most days but check forecasts—the operators cancel in bad weather. Shoes that grip, quick-dry clothing, a sun hat, and a small dry bag make the trip more comfortable. Keep voices low near reed beds to avoid disturbing birds; kingfishers and egrets are common visitors.
This is low-impact paddling with high visual reward: wide water, the geometric line of the dam, and forested hills that change color with the seasons. It’s an approachable way to experience inland Shikoku—relaxed, scenic, and quietly instructive for new paddlers.
