DESCRIPTION:To prepare for JWST/NIRSpec deeper observations\, we have inve
 stigated chemical abundances and kinematics of local (z=0.01) extremely me
 tal-poor galaxies (EMPGs) as analogs of high-z primordial galaxies.\nOur c
 hemical enrichment models suggest that high Fe/O ratios of EMPGs (approx. 
 solar abundance) can be explained by supernovae originating from metal-poo
 r massive stars (> 30 Msun). Our Subaru IFU observations also show that EM
 PGs have rotational velocities (v_rot = 5-23 km s-1) lower than their velo
 city dispersions (σ = 17-31 km s-1)\, which suggests that high-z primordi
 al galaxies are also dispersion-dominated systems (i.e.\, v_rot/σ < 1).\n
