Promptness of the data processing of the international VLBI observations has been continuously improvedin the past decades. In particular, e-VLBI technique has proved that it has a capability to shorten the latency by transferring the observed data to the correlator by using high speed communication networks. The method has been introduced to routine intensive VLBI sessions to monitor dUT1. To improve the promptness even further, we started an initiative to develop automated data transfer and data processing systems using Europe-Japan baselines.On February 21, 2008, we succeeded to demonstrate the effectiveness of the developed systems and estimated the dUT1 parameter 3 minutes 45 seconds after the last scan of the one hour intensive style e-VLBI session. This achievement was realized by the developments of the K5/VSSP32 data acquisition terminal, automated data processing and analysis software.
