Local Weather Broadcast Service provides local weather data collected at the major lighthouses throughout the country to vessels navigating on the sea．
Formerly，upon the request from vessels，the lighthouse provided data of wind direction，Wind speed，visibility，weather，waves and swells col1ected at the lighthouse．Later，upon request for broadcasting of meteorological and marine information，in June，1949, regular information service by wireless telegraphy was started. In 1954，for small boats that are not equipped with wireless telegraphy，a radio telephone system was developed so that information may be received by the radio．
The system has gradually been developed to cover all vessels．
In response to the request of the users，further development of the telephone service and frequent broadcasts are carried out to improve the service for the users．
