Currently your options are to fly from Honolulu to four cities in Japan – Tokyo, Osaka, Nagoya, or Fukuoka. Keep in mind that the peak seasons for travel between Japan and Hawaii include Christmas, New Years, Golden Week (late April-May), and the Summer/Obon Season, so fares will likely be higher during these times as demand increases.

As the capital of Japan, Tokyo is the most common entry point for those visiting the country.
