Pack layers, a warm coat, and cold-weather essentials for January travel between Boston Logan International Airport (BOS) and Narita International Airport (NRT). Expect Boston to have snow and potential airport de-icing delays; arrive earlier and monitor airline alerts. At Narita, bring an adapter for Japan (Type A/B outlets) and a compact umbrella for occasional showers. Buy travel insurance that covers weather disruptions and consider refundable or flexible tickets for trans-Pacific travel. For transfers, pre-book trusted options: Logan Express or licensed taxis in Boston, and Narita Express, Keisei Skyliner, or airport limousine buses in Japan. CTA: Prepare now — check weather forecasts, pack smart, and book flexible trans-Pacific fares for January travel.
