We present a comparison of the SCUBA half degree extragalactic survey (SHADES) at 450µm, 850µm and 1100µm with deep guaranteed time 15µm AKARI FU-HYU survey data and Spitzer guaranteed time data at 3.6-24µm in the Lockman hole east. The AKARI data was analysed using bespoke software based in part on the drizzling and minimum-variance matched filtering developed for SHADES, and was cross-calibrated against ISO fluxes. Our stacking analyses find AKARI 15 µm galaxies with >200µJy contribute >10% of the 450µm background, but only <4% of the 1100µm background, suggesting that different populations contribute at mm-wavelengths. We confirm our earlier result that the ultra-deep 450µm SCUBA-2 cosmology survey will be dominated by populations already detected by AKARI and Spitzer mid-infrared surveys. The superb mid-infrared wavelength coverage afforded by combining Spitzer and AKARI photometry is an excellent diagnostic of AGN contributions, and we find that (23-52)% of submm-selected galaxies have AGN bolometric fractions f_AGN>0.3.
