Quick Facts

History & Context

Geographical Setting and Coastal Topography Ichimatsu Beach, nestled along the eastern coast of Chōsei Village in Chiba Prefecture, presents a diverse coastal landscape shaped by centuries of marine and fluvial processes. Situated at approximately 35.5°N latitude and 140.3°E longitude, the beach extends roughly 1.5 kilometers north to south, bordered to the north by the mouth of the Bōsō River and to the south by rocky headlands that demarcate entry into neighboring Onjuku Town. The gently sloping sandy shore transitions seaward into shallow sandy shoals, which gradually deepen into the Pacific Ocean’s coastal shelf. Tidal ranges average around 1.8 meters, with semi-diurnal tides producing two high and two low water intervals each day. Prevailing onshore winds blow from the southeast, particularly active during the late spring and early summer monsoon season, generating gentle but consistent wave action that redistributes sand and shapes the beach’s dynamic profile.
