If you leave Tokyo by plane at 7 am, you will arrive in Honolulu at approximately 7:45 pm the previous day.

Due to a massive gap in time zones, Honolulu is 19 hours behind Tokyo. Subtracting the 7 hour and 45 minute flight time between these two cities gives us a trip difference of 11 hours and 15 min. Therefore, you would actually land in Hawaii more than 11 hours before you left Japan!
