*Numbers in the first column denote the order of establishment. Tide stations that have been moved are also numbered according to the order of establishment.
*"G.S.A.T" in the column of the type of tide gauge is an abbreviation of Geospatial Information Authority of Japan Automatic Tide Gauge. In Japan, the gauge is called "High resolution automatic tidal system."
 
  • The height of the fixed points are that of FY 2000, which were revised on April 1, 2002.
  • The data for Aburatsubo Tide station is that from the new station collected since January 1, 1997.
  • The data for Soma Tide station is that from the new station collected since September 1, 2015.
  • Method for calculating tidal height: Tidal height = height of the fixed point - constant of the tidal datum plane + tidal level
