The second order gravimetric network in Japan is divided into six local nets. A gravity value at each station is determined from the gravity difference observed and adjusted in the net work in which that station is included referring only to the local pendulum station. The net work of the Tohoku district is separated from that of Hokkaido district by sea and there has been no direct gravimetric connection. In June, 1961, a direct tie measurement with gravimeters between Aomori (Asamushi Tidal Station) and Hakodate (Bench Mark No. 6327) was carried out by the members of Geographical Survey Institute in order to connect the two Tohoku and Hokkaido net works. The result is; gB. M.6327 - gAsamushi Tidal Station= + 17.24±0.04 mgal Some discussions about the drift and scale value of the used gravimeters are given and the comparison of Tohoku net work with that in Hokkaido is made.
