Gravimetric connections of the first order gravity stations were carried out in and around the Kitakami district, Northeastern Japan, by means of the LaCoste & Romberg gravimeter (model G) No. 348 taking the first order gravity station in Kanazawa as a reference one. The maximum gravity difference between Kanazawa and stations amounted up to about 500 mgals. Scale constant of the gravimeter was revised through the project of the gravimetric connection along the Circum Pacific Zone by using nine gravimeters, which was carried out during 1980 to 1983. Observed gravity values calculated by using the original scale constant produced maximum errors about 0.3 mgal. The revised scale constants reduced them to only -0.005±0.024 mgal.
