Hidden and visible star formation in galaxies: new insights from AKARI
and Herschel surveys

The surveys recently performed by AKARI and Herschel allow us to
perform a complete energetic budget in galaxies observed both in
UV-visible and FIR on a large range of redshift (z=0 to 2).  Our work
is based on the AKARI all sky survey, fields from the GT key program
Herschel/HerMES and the GO key program H-GOODS.  Our tool is a SED
fitting analysis from the FUV to the FIR: I will briefly discuss the
code, CIGALE, developed to this purpose. Then I will discuss results
obtained about the properties of galaxies observed in UV-visible
and/or in FIR in terms of dust attenuation and star formation.
