Kujukuri Beach
A vast, 60km sweep of Pacific-facing sand on Chiba's Boso Peninsula - Japan's second-longest beach - and one of the most frequently recommended beginner-through-advanced kite spots within reach of Tokyo. Long, consistent beach-break surf and open sand make it popular for kiteboarding and SUP alongside dedicated surfing.

Monthly wind statistics
Station: Mobara (WeatherSpark (MERRA-2 reanalysis climatology), ~9 km) — Windfinder blocked (HTTP 429) this session; WeatherSpark modeled climatology used instead, so prob_ge_4bft_pct is null. Kujukuri itself has no WeatherSpark entry; nearest is Mobara town (~9 km inland from the beach). The batch flags Aug as the known-best month, likely driven by typhoon-season and sea-breeze wind events this monthly-average model does not resolve well.
