December offers festive experiences on both ends of the DFW to NRT journey. In Dallas/Fort Worth, holiday parades, the ZooLights at the Dallas Zoo, and seasonal markets create pre-flight festivities. In Tokyo and Yokohama (accessible from Narita International Airport (NRT)), December is illumination season — spectacular light displays at Roppongi, Omotesando, and Yokohama Minato Mirai are major draws. New Year’s Eve and Shogatsu preparations start late December, so book accommodations early. If you plan to combine city sightseeing with nearby escapes, consider Chiba, Saitama, or Mount Fuji for winter landscapes accessible from NRT.
