Cached-fare history: across 9 months, Feb is the cheapest for SF → TYO. Best time to be there: Mar–May · Oct–Nov.
Fares bottom out in February around $496 and peak in June near $1,106 — a $610 spread across the 9 months we track. The cheapest itinerary we are tracking makes one stop and takes about 19.5 hours outbound, on a 9-night trip — ticketed under Cathay Pacific, which on a connecting fare need not operate every leg. At $496 for 8,275 km each way, that works out to about $30 per 1,000 km flown. That is well under the $44 that long-haul fares on this board typically run. Of the 23 departure cities we track at a similar distance from Tokyo, this is the cheapest right now — though Stockholm is within a few dollars. It is also the cheapest of the 30 routes of similar length we watch out of San Francisco.

How far in advance should I book SF → Tokyo?
We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. What we can measure is which month is cheap: across 9 months of cached fares, Feb comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from San Francisco to Tokyo?
The current cheapest fares involve a connection, ticketed under Cathay Pacific. Nonstop options exist on many dates at higher prices — check the live search for your exact dates.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on September 1). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
