About this warning
NAVAREA XI 0484/26 is a navigational warning for NAVAREA XI (East Asia / Japan), broadcast by the Japan Coast Guard (JCG) under the World-Wide Navigational Warning Service (WWNWS). Helm.Warning aggregates these broadcasts daily and plots warnings with resolved geometry on the live map.
Helm.Warning is a convenience copy of these broadcasts, not an official source of Maritime Safety Information. Always verify against official channels (NAVTEX, Inmarsat SafetyNET) as required by SOLAS — see the about and disclaimer page for the full safety notice.
Situational awareness only. Not a substitute for GMDSS, NAVTEX or SafetyNET broadcasts. Official broadcasts and the Master’s judgment always take priority.
