When this route gets cheap.
Fares bottom out in November around $317 and peak in February near $479, 51% dearer, across the 9 months we track. The cheapest itinerary we are tracking flies Thai AirAsia X nonstop and takes about 7.5 hours outbound, on a 12-night trip. At $317 for 4,599 km each way, that works out to about $34 per 1,000 km flown. That is below the $43 per 1,000 km typical of medium-haul fares here. Across the 4 departure cities we track at a similar distance from Bangkok, this fare ranks 3rd — 28% above the $248 from Seoul. It is also the 3rd cheapest of the 7 routes of similar length we watch out of Tokyo. The best time to be in Bangkok: Nov–Feb.

Good to know
TYO → BKK, answered.
Is $317 a good price for Tokyo to Bangkok?
Only slightly. The seasonal median is around $385 round-trip and this fare is 18% under it. 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 Tokyo to Bangkok?
Across 9 months of cached-fare history, Nov comes out cheapest on this route. The best months to actually be in Bangkok are Nov–Feb — when those overlap, that's your window.
How far in advance should I book TYO → Bangkok?
We do not publish a number for this, because we cannot measure it yet.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, Nov comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Tokyo to Bangkok?
Yes — the current board includes nonstop fares (Thai AirAsia X). The outbound leg runs around 7.5 hours.
Are these prices guaranteed?
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.
