We study outflows in 130 galaxies with -22<MUV<-16 at z=3-9 identified inJWST NIRSpec and NIRCam WFSS data taken by the ERO, CEERS, FRESCO, GLASS, andJADES programs. We identify 30 out of the 130 galaxies with broad components ofFWHM~200-700 km s$^{-1}$ in the emission lines of H${\alpha}$ and [OIII] thattrace ionized outflows, and find no excesses from the star-formation mainsequence. Four out of the 30 outflowing galaxies are Type-1 AGN whoseH${\alpha}$ emission lines include line profile components as broad asFWHM>1000 km s$^{-1}$ while one galaxy is identified as a Type-2 AGN by highionization emission lines. With the velocity shift and line widths of theoutflow broad lines, we obtain ~80-500 km s$^{-1}$ for the outflow velocities.We find that the outflow velocities are slower than low-z galaxies with similarSFRs, which may be explained by the low stellar masses of high-z galaxies. Theoutflow velocities of AGNs are large but not significantly different from theothers. Interestingly, these outflow velocities are typically not high enoughto escape from the galactic potentials, possibly suggesting fountain-typeoutflows. We estimate mass loading factors ${\eta}$ to be 0.1-1 that are notparticularly large, but comparable with those of z~1 outflows. The largefraction of galaxies with outflows (30% with high resolution data) providesconstraints on outflow parameters, suggesting a wide opening angle of >45 degand a large duty-cycle of >30%, which gives a picture of more frequent andspherical outflows in high-z galaxies.
