5pm in Karachi is 9pm in Tokyo

When it’s 9am in Karachi, it’s 1pm in Tokyo. Tokyo is 4 hours ahead Karachi. Neither city observes daylight saving time, so this offset is fixed year-round. The best time to schedule calls between the two cities is 9am to 2pm Karachi time (which is 1pm to 6pm in Tokyo). For BPO teams and remote workers bridging Karachi and Tokyo, morning standups on one side align with afternoon availability on the other. In practice, teams in Karachi tend to take early-morning calls to reach Tokyo during standard afternoon hours, while Tokyo counterparts can schedule near end of day. Asynchronous handoffs using shared documents or recorded video updates help bridge the hours when schedules do not overlap.
