Fares bottom out in January around $651 and peak in December near $1,225, 88% dearer, across the 5 months we track. The cheapest itinerary we are tracking makes one stop and takes about 15 hours outbound, on a 8-night trip — ticketed under Air China, which on a connecting fare need not operate every leg. At $651 for 10,318 km each way, that works out to about $32 per 1,000 km flown. That is below the $44 per 1,000 km typical of long-haul fares here. Across the 29 departure cities we track at a similar distance from Osaka, this fare ranks 3rd — 12% above the $582 from Brussels. That puts it in the cheaper half of the 36 routes of similar length we watch out of Barcelona, where the middle fare is $767. The best time to be in Osaka: Mar–May · Oct–Nov.

We do not publish a number for this, because we cannot measure it yet.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 5 months of cached fares, Jan comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
The current cheapest fares involve a connection, ticketed under Air China. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
No — these are cached fares found on real searches (this one on 17 October). 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.
