San Francisco → Tokyo flights

Target $335–$344 for SFO–Tokyo — budget up to $378 for flexibility

Key takeaways

• Median fare is $344 — that's a reasonable planning number for a one-way cheapest-available fare on this route.
• Bottom-quartile fares sit at $335 or below — a $9 gap from the median, meaning genuine low fares do surface but don't require heroic timing.
• The price ceiling in this window was $411, a 23% jump above median; the $378 p75 threshold is your realistic 'bad luck' budget.
• A 24% spread (low $332 to high $411) is moderate — meaningful enough that monitoring fares pays off, but not so volatile that you need to obsess over daily checks.
• No dominant carrier signal was visible in this dataset, so flexibility across airlines is more useful than loyalty to a single brand here.

The full picture

Across 30 daily snapshots of the cheapest cached fares for San Francisco to Tokyo (SFO–NRT), prices clustered tightly at the low end: the 25th percentile was just $335 and the median only $344 — a $9 gap. That compression is meaningful. It tells you the floor on this route isn't an elusive flash sale; it's a regularly available fare tier. If you're budgeting a trip, $344 is a defensible planning number, and anything at or below $340 represents a genuinely good result.

The upper end of the range is where the real risk lives. The 75th percentile hits $378 — a $34 premium over median — and the single highest observation in the window was $411. That 24% spread between low and high is moderate by transpacific standards, which historically see much wilder swings. What it suggests in practical terms: fares on this route can deteriorate meaningfully if you wait too long or book into a constrained departure window. The sweet spot, based on this data, is acting when fares are in the $332–$344 band rather than holding out for a further drop that the data doesn't strongly support.

Because no dominant carrier pattern emerged from this dataset, there's no compelling case to wait specifically for one airline's sale cycle. Your best lever is price-alert tools set around the $335–$340 mark — treat anything at p25 or below as a buy signal, and treat $378 as the ceiling before you're overpaying relative to what this route typically offers. One honest caveat: 30 snapshots reflect a single rolling window and don't capture seasonal demand shifts, such as the premium typically seen around Golden Week or year-end holidays. If your travel dates overlap with Japanese public holidays, expect this entire distribution to shift upward.
