Boston to Tokyo Narita Flights (BOS to NRT): Connections, Flight Time and the Haneda Alternative

Check the airport first: Boston's nonstop goes to Haneda

As of recent schedules there is no regular nonstop between Boston and Tokyo Narita. Japan Airlines does fly Boston to Tokyo nonstop, but that flight lands at Haneda, the airport closer to the city. If you have searched for Narita because you assumed it was Tokyo's main gateway, compare both: for central Tokyo, Haneda is faster on the ground and the nonstop saves hours in the air.

If you specifically need Narita, for a connection onward within Asia, a hotel near the airport, or a trip into Chiba, you will connect once. The practical routings:

• United and ANA via Newark, Washington Dulles or Chicago O'Hare, all of which have Narita nonstops on one or both airlines. Star Alliance, one ticket.
• American and Japan Airlines via Chicago, Dallas/Fort Worth or Los Angeles, where JAL and American fly to Narita. Oneworld, one ticket.
• West Coast routings via San Francisco or Los Angeles on United, Delta partners or ZIPAIR, the low-cost arm of JAL.

Newark and Chicago give the shortest total trips from Boston. The West Coast adds a long domestic flight but sometimes prices lower.

Flight time and distance

Boston to Narita is roughly 6,730 miles (about 10,830 km) in a straight line, over the top of Canada and Alaska. A nonstop would take about 14 hours westbound; with a connection, plan on 17 to 20 hours door to door. The Newark or Chicago leg takes one to two and a half hours, the layover two to three, and the flight to Narita 13 to 14 hours from the East Coast or 11 to 12 from the West Coast.

The return is shorter in the air thanks to the jet stream: Narita to the East Coast is typically 12 to 13 hours. You cross the International Date Line heading west, so you land in Tokyo the day after you leave Boston. Coming home you arrive on the same calendar day you depart, often only a few hours later by the clock.

Leaving from Logan

Logan has four terminals, A, B, C and E, connected by walkways and free shuttle buses. United uses Terminal B, American Terminal B as well, Delta Terminal A, and Japan Airlines and most other international carriers Terminal E. If your first flight is domestic, 90 minutes is enough, but bring your passport to check-in because the agent needs it to issue the Narita boarding pass, and ask that your bags be tagged through to NRT.

Logan is unusually easy to reach: the free Silver Line SL1 bus runs from every terminal to South Station in 20 to 30 minutes, the Blue Line subway is a short free shuttle away, and Logan Express coaches serve the suburbs. Parking fills on holiday weekends.

Arriving at Narita and getting into Tokyo

Narita has three terminals. Terminal 1 handles ANA, United and most Star Alliance partners; Terminal 2 handles Japan Airlines and American; Terminal 3 is the low-cost terminal used by ZIPAIR, linked to Terminal 2 by a walkway. Confirm your terminal the day before, because assignments change. Immigration is efficient if you have completed the Visit Japan Web registration, which gives QR codes for immigration and customs in place of paper forms.

Narita is about 60 km from central Tokyo, so plan the last leg:

• Narita Express (N'EX): the JR train to Tokyo Station in about an hour, continuing to Shinjuku, Shibuya and Yokohama. Reserved seats and room for bags, and covered by the Japan Rail Pass.
• Keisei Skyliner: the quickest option to Nippori and Ueno at around 40 minutes, best for the north and east of the city.
• Limousine bus: direct to major hotels in 75 to 120 minutes depending on traffic. The easy choice with heavy bags or a late arrival.
• Taxi: comfortable but very expensive for the distance; fixed-fare taxis exist, but the trains win for most of the day.

Trains stop around midnight; a late arrival means the bus or a taxi.

When to fly and when to book

Japan's calendar sets the peaks. Cherry blossom season in late March and early April, Golden Week at the start of May, Obon in mid-August and the New Year holiday are the most expensive and crowded periods, and seats from Boston connections sell out months ahead. Late October and November bring clear autumn weather and fall colours around Tokyo with softer demand. January and February are cold, dry and the quietest, and usually the cheapest time to fly.

June is the rainy season, and late August through October carries typhoon risk, when a storm can close Narita for a day. Boston's own winter storms are a factor for the first leg from December to March; a morning departure to the hub leaves more recovery room. For the peak periods, book three to five months ahead; otherwise six to ten weeks is usually enough.

Entry requirements and documents

As of recent rules, US passport holders can visit Japan for short tourist stays without a visa, but rules change and other nationalities differ, so check the Ministry of Foreign Affairs of Japan before you book. Your passport should be valid for the whole stay, and airlines may ask for an onward or return ticket at check-in.

Japan restricts several medicines that are routine in the US, including some decongestants and ADHD stimulants. Check the rules for anything you take regularly and carry a doctor's letter where required.

Time zones and jet lag

Tokyo is 13 hours ahead of Boston during US daylight saving and 14 hours ahead in winter; Japan does not change its clocks. That is close to a full flip of day and night. Westbound you usually land in the Japanese afternoon or evening and can go to bed at a normal local hour, which makes it the easier direction. Eastbound you land in Boston in the afternoon of the same day you left and most people feel it for four or five days. Daylight, a light dinner and no long nap on arrival help most.

What travellers on this route get wrong

The most common mistake is searching Narita out of habit and missing that Boston's only Tokyo nonstop goes to Haneda, which is also closer to the city. The second is a one-hour connection at Newark or Chicago; the Narita flight goes once a day and a short delay out of Logan costs a whole day, so book two hours. The third is skipping Visit Japan Web and queueing to fill in paper forms on arrival.
