A cooperative observation with Hida observatory and Hinode satellite was performed on an emerging flux region .
The successive Ca \emissiontype II K spectro-heliograms of the emerging flux region were taken by the Domeless Solar Telescope of Hida observatory .
Hinode observed the emerging flux region with Ca \emissiontype II H and Fe \emissiontype I Stokes IQUV filtergrams .
In this study , detailed dynamics and temporal evolution of the magnetic flux emergence was studied observationally .
The event was first detected in the photospheric magnetic field signals .
3 minutes later , the horizontal expansion of the dark area was detected .
And then , 7 minutes later than the horizontal expansion , the emerging loops were detected with the maximal rise speed of 2.1 km/s at chromospheric heights .
The observed dynamics of emerging magnetic flux from the photosphere to the upper chromosphere is well consistent with the results of previous simulation works .
The gradual rising phase of flux tubes with a weak magnetic strength was confirmed by our observation .
