Tide Charts
Calculates high and low tides at the specified 202 locations along the Japanese coast and displays a tide chart.
The tide level forecasts (astronomical tide levels) for each location are calculated and may differ from actual observed tide levels.
・The calculated tidal information is intended as a reference for coastal activities such as fishing and shellfishing.
・Changes over time, such as earthquakes, natural disasters, coastal construction, and crustal movements, are not taken into account.
・For navigation purposes, please be sure to use the tide tables issued by the Japan Coast Guard.
・We assume no responsibility whatsoever for any accidents, problems, or other issues arising from the use of these calculation results.
