Tokyo to San Francisco is the classic trans-Pacific gateway between Japan and the US West Coast, and the gap between the cheapest and the dearest way to fly it is unusually wide. Every one of the lowest returns we can find is a ZIPAIR non-stop out of Narita at around ¥127,000, and on the very same October dates the next cheapest option is a one-stop at about ¥336,000 — so the choice here is not a few thousand yen, it is roughly a third of the price. This guide covers who actually flies it, what the two fare tiers really cost, and when to book.
Route: Tokyo (Haneda HND / Narita NRT) → San Francisco (SFO)
Distance: approximately 8,300 km (5,150 miles)
Non-stop flight time: about 9h 15m eastbound to San Francisco — the non-stops we track run 9h 10m to 9h 35m — and about 11h 20m on the return on the ZIPAIR non-stop, flying into the headwinds
Direct flights: Yes — ZIPAIR flies non-stop from Narita and is behind every one of the cheapest fares we track, while United, ANA and Japan Airlines fly full-service non-stops from Haneda and Narita. One-stop routings via Doha or Istanbul exist, but they cost far more, not less.
Fares from Tokyo to San Francisco (JPY)
This is a business-and-leisure route, so fares stay fairly firm but spike around Japan’s holiday peaks: Golden Week (late April to early May), the summer school break, Obon (mid-August) and the New Year period. The quiet windows are February and the autumn shoulder, either side of those peaks. We deliberately do not print a yen figure against each month, because we can only price the dates actually on sale — and when we checked, the cheapest fares available all happened to fall in October. The table below tells you which months to avoid; the live fares above tell you what you will pay.
| Month | Demand | What that means for the fare |
|---|---|---|
| January | medium | quiet once the New Year rush clears |
| February | low | one of the calmest months to travel |
| March | medium | picks up towards the spring holidays |
| April | high (Golden Week) | avoid late April to early May |
| May | medium-high | eases once Golden Week ends |
| June | medium | steady, before the summer break |
| July | high (summer) | school holidays push fares up |
| August | very high (Obon) | the busiest and dearest window |
| September | medium | the shoulder begins |
| October | low-medium | shoulder season; today’s cheapest fares fall here |
| November | medium | still good value before December |
| December | high (year-end) | the New Year peak is expensive |
Checked against every return fare on sale as we write: the cheapest is a ZIPAIR non-stop from Narita at about ¥125,000, and ZIPAIR’s fares cluster tightly between ¥125,000 and ¥128,000, all of them on October departures. Nothing else comes close on those dates — the next cheapest October fare is a one-stop via Doha at about ¥336,000. Elsewhere in the same sample a one-stop via Istanbul runs from about ¥332,000, and a United non-stop on August dates about ¥348,000. There is no middle tier on this route: anything near ¥125,000–¥130,000 is the budget non-stop doing its job and is worth booking, and the next step up is close to three times the price. Add bags and a seat to the ZIPAIR fare before you compare it.
Airlines on this route
Non-stop (about 9¼ hours eastbound):
- ZIPAIR — JAL’s long-haul budget arm, non-stop from Narita, and the carrier behind every one of the cheapest fares we track on this route. Base fares in economy are a fraction of the full-service price, with bags, seats and meals charged separately, so price it all-in before comparing.
- United — full-service non-stop into its own San Francisco hub, which gives the easiest onward connections across the US. In our fare sample its returns sit near ¥348,000 on August departures, at the top of the range rather than the bottom.
- ANA — full-service non-stop from Tokyo on the Boeing 787, consistently top-rated in economy and with the widest schedule. It does not appear among the cheapest fares we track, so expect full-service pricing.
- Japan Airlines — full-service non-stop from Tokyo, with a strong hard product and generous baggage on standard fares. Like ANA, it prices well above the ZIPAIR non-stop.
One-stop (slower and dearer here):
- Qatar Airways via Doha and Turkish Airlines via Istanbul are the one-stop itineraries that actually show up in our fare data, from about ¥332,000 in the sample we checked. They are the long way round to San Francisco and they are not cheaper than flying direct — on this route a connection buys you nothing at all.
With several non-stop operators competing, a connection almost never wins on price here. Compare ANA, JAL and United for comfort, and price ZIPAIR with your bags added — on the fares we can currently see, even a fully loaded ZIPAIR ticket stays a long way under the full-service alternatives.
When to book & how to save
- Book 2–4 months ahead for the best balance of price and seat choice; trans-Pacific fares rarely improve in the final weeks.
- Avoid the Japanese holiday peaks — Golden Week, mid-August Obon and the year-end break are the priciest and busiest departure windows.
- Look at February and the autumn shoulder — the quiet months either side of Japan’s holiday peaks. When we checked live fares, every one of the cheapest on sale departed in October.
- Price ZIPAIR all-in: its base fare looks cheap, but add checked bags and a seat before comparing it with ANA, JAL or United, which include a bag on standard fares.
- Expect Narita for the cheap fare: Haneda is closer to central Tokyo, but every one of the lowest fares we track leaves from Narita on ZIPAIR — budget the extra time to the airport.
Arriving in San Francisco
Non-stop flights land at San Francisco International (SFO), about 21 km south of downtown. The easiest way in is BART from the International Terminal straight into the city (around 30 minutes; roughly ¥1,500 equivalent). A taxi or rideshare downtown runs about ¥7,000–¥10,000 equivalent depending on traffic. If you are connecting onward in the US, SFO is a major hub with fast links across the network.
Frequently asked questions
How long is the flight from Tokyo to San Francisco?
Non-stop flights take about 9 hours 15 minutes eastbound from Tokyo to San Francisco, helped by the jet stream — the non-stops we track run between 9h10m and 9h35m. The return, flying into the headwinds, is longer — about 11 hours 20 minutes on the ZIPAIR non-stop.
Are there direct flights from Tokyo to San Francisco?
Yes, and the non-stop is also the cheapest way to fly it. ZIPAIR flies non-stop from Narita and is behind every one of the lowest fares we track, while United, ANA and Japan Airlines fly full-service non-stops. One-stop routings via Doha or Istanbul exist but cost close to three times as much.
How much does it cost to fly from Tokyo to San Francisco?
There are two clear tiers, not one average. The cheapest returns on sale are ZIPAIR non-stops from Narita at about ¥125,000–¥128,000 before bags. Full-service non-stops and one-stop routings start much higher, from roughly ¥332,000. Averaging the two would give a number nobody actually pays.
What is the cheapest month to fly from Tokyo to San Francisco?
The quiet months either side of Japan’s holiday peaks: February and the September–November shoulder. When we last checked live fares, every one of the cheapest returns on sale was an October departure at about ¥125,000 on ZIPAIR. Avoid Golden Week, mid-August Obon and the New Year period, which are the busiest and most expensive windows.
Which airlines fly from Tokyo to San Francisco?
Non-stop: budget carrier ZIPAIR from Narita, plus full-service United, ANA and Japan Airlines. ZIPAIR is behind every one of the cheapest fares we track and charges for bags and seats separately; the full-service carriers include a checked bag on standard economy fares and price around three times higher.
Which airport do I fly into in San Francisco?
All non-stop flights arrive at San Francisco International (SFO), the region’s main airport and a major connecting hub. BART rail runs directly from the airport into downtown, making it easy to reach the city or connect onward across the United States.
How far in advance should I book Tokyo to San Francisco flights?
Aim to book 2 to 4 months ahead. Fares on this trans-Pacific route tend to firm up as departure nears, especially around Golden Week, the summer break and the year-end peak, so booking early almost always wins.
Is it cheaper to fly on weekdays?
Often, yes — midweek departures (Tuesday to Thursday) are usually a little cheaper than weekend flights, and pairing a weekday outbound and return can shave several thousand yen off the total. Shifting your dates by a day or two is one of the simplest ways to cut the fare.
