Hanakago (Minamiboso)

Hanakago is a sandy beach break in Minamibōsō (Minamiboso) known for fun, hollow-to-ordinary waves with both left and right options. Sources describe it as regularly surfable, with a wave character ranging from manageable small surf to bigger sets that can push beyond about 2 meters. Wave conditions are generally reported as good, with short rides typically under 50 meters. It’s described as exposed to the elements, so conditions can change quickly depending on wind and swell direction. The most favorable swell direction is southeast to east, with typical working heights around roughly 0.5–2 meters; when swell gets too large, the wave can close out. Wind at Hanakago is most beneficial when northwest to west winds are offshore, helping groom the surface. A mixed wind picture is noted in the spot-level descriptions, and wind reliability is reported as moderate with light gustiness; a typical reported range is about 10–20 knots. For safety, the biggest concerns are rip currents (especially as swell increases) and crowded lineups on weekends. Rising and falling tides are commonly mentioned as giving the best wave movement, and weekday sessions are often much less busy than weekends. Emergency medical support is available via Japan’s standard services (119 for ambulance/fire) and Coast Guard coverage (118).
