This study was conducted to investigate the comparison of storability on film sources and storage temperature and determine the proper condition for fresh Japanese mint in U storage. The fresh weight in storage was maintained well more than 40$\mu$m ceramic film(CE 40) thickness. The carbon dioxide, ethylene, and acetaldehyde contents in 80$\mu$m ceramic film(CE 80) was higher than those in CE 40. Those were not different among the storage temperatures, rather, those in 3$^{\circ}C$ and 1$^{\circ}C$ storage were higher than those in 1$0^{\circ}C$. The chlorophyll contents loss was promoted by above 5％ water loss and 0.5ppm ethylene contents, but mote than 4％ carbon dioxide contents restrained from degrading chiorophyll. The storage period in 3$^{\circ}C$ was 30 days that was twice longer than those in other storage temperatures. The visual quality was higher in CE 40 at 3$^{\circ}C$, and this plot was lowest in ion leakage that was shown the degree of chilling injury. It was concluded that storage temperature of at 3$^{\circ}C$ and packaged ceramic 40$\mu$m film to increase storability of Japanese mint would be favorable.
