Additional information 
Other relevant informationThe TGBM is on top of the stilling well. Another benchmark is near the station which is used to decide the height of the TGBM and monitor the height of the tide station. This second benchmark is levelled in to the nearest first class benchmark which is part of the network operated by the Geographical Survey Institute, Ministry of Construction. Heights of benchmarks are described as above Tokyo Peil (TP).
