Cached-fare history: across 9 months, May is the cheapest for IST → KIX. Best time to be there: Mar–May · Oct–Nov.
Fares bottom out in May around $685 and peak in February near $939 — a $254 spread across the 9 months we track. The cheapest itinerary we are tracking makes one stop and takes about 13.5 hours outbound, on a 14-night trip — ticketed under China Southern, which on a connecting fare need not operate every leg. At $685 for 8,746 km each way, that works out to about $39 per 1,000 km flown. That is below the $44 typical of long-haul fares here. Across the 27 departure cities we track at a similar distance from Osaka, this fare ranks 4th — 38% above the $498 from San Francisco. That puts it in the cheaper half of the 34 routes of similar length we watch out of Istanbul, where the middle fare is $685.

IST → KIX, answered.
Is $685 a good price for Istanbul to Osaka?
Only slightly. The seasonal median is around $725 round-trip and this fare is 6% under it, about $40. We do not call a drop notable until 20%, so this is an ordinary price for the route rather than a reason to hurry.
What is the cheapest month to fly from Istanbul to Osaka?
Across 9 months of cached-fare history, May comes out cheapest on this route. The best months to actually be in Osaka are Mar–May · Oct–Nov — when those overlap, that's your window.
How far in advance should I book IST → Osaka?
We do not publish a number for this, because we cannot measure it yet.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, May comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Istanbul to Osaka?
The current cheapest fares involve a connection, ticketed under China Southern. 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.
