Fares bottom out in September around $387 and peak in December near $525 — a $138 spread across the 4 months we track. The cheapest itinerary we are tracking makes one stop and takes about 8.5 hours outbound, on a 6-night trip — ticketed under Jeju Air, which on a connecting fare need not operate every leg. At $387 for 4,914 km each way, that works out to about $39 per 1,000 km flown. That is about the $39 typical of medium-haul fares here. Across the 5 departure cities we track at a similar distance from Osaka, this fare ranks 3rd — 35% above the $286 from Bangkok. For context, the middle fare among the 11 routes of similar length we watch out of Singapore is $371.

SIN → KIX, answered.
Is $387 a good price for Singapore to Osaka?
Only slightly. The seasonal median is around $450 round-trip and this fare is 14% under it, about $63. 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 Singapore to Osaka?
Across 4 months of cached-fare history, Sep 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 SIN → 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We do not publish a number for this, because we cannot measure it yet.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 4 months of cached fares, Sep comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Singapore to Osaka?
The current cheapest fares involve a connection, ticketed under Jeju Air. 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.
