We calculate thermodynamic quantities and transport coefficients of ahadronic gas using a Monte Carlo hadronic collision event generator URASiMA.The obtained shear viscosity to entropy density ratio of the hadronic gas isapproximately 0.3 -- 0.6 in the range $T$ = 100 -- 180MeV and is quiteinsensitive to the baryon number density.Comment: 7 pages, 6 figure
