| Tide gauge benchmarks | Japan Met. Agency Benchmark bolt inside tide gauge hut, adjacent to stilling well |
| Benchmark relationships | Tide Gauge Zero (TGZ) = 1.404m below Tokyo Peil (Mean Sea Level of Tokyo Bay) TGZ = 3.606m below TGBM (from 1976 onwards) |
| Auxiliary benchmarks | Tide station BM 2.414m above Tokyo Peil (1997). |

| Additional information | |
| Other relevant information | The 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). |
