| Tide gauge benchmarks | Japan Met. Agency Benchmark bolt inside tide gauge hut adjacent to stilling well |
| Benchmark relationships | Tide Gauge Zero (TGZ) = 5.453m below TGBM (from 1966 onwards) |
| Auxiliary benchmarks | Tide Station BM 6.342m above Okinawa height standard (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). |
