Tokyo is exactly 1 hour ahead of Perth year-round. When it's 3:00 PM in Perth, it's 4:00 PM in Tokyo. Neither city observes daylight saving time, so this difference never changes.
Perth uses Australian Western Standard Time (AWST, UTC+8) while Tokyo uses Japan Standard Time (JST, UTC+9). The 1-hour difference remains constant throughout the year.
Excellent business hour overlap! 9:00 AM - 5:00 PM Perth corresponds to 10:00 AM - 6:00 PM Tokyo. Almost perfect alignment for business coordination.
Perth's mining industry has strong ties to Japanese steel and manufacturing companies. Iron ore exports from Western Australia to Japan make this an important business corridor.
