Fares bottom out in September around $337 and peak in August near $521 — a $184 spread across the 10 months we track. The cheapest itinerary we are tracking makes one stop and takes about 7 hours outbound, on a 14-night trip — ticketed under Juneyao Airlines, which on a connecting fare need not operate every leg. At $337 for 4,599 km each way, that works out to about $37 per 1,000 km flown. That is below the $39 typical of medium-haul fares here. Across the 3 departure cities we track at a similar distance from Tokyo, this fare ranks 2nd — 12% above the $301 from Singapore. It is also the 3rd cheapest of the 7 routes of similar length we watch out of Bangkok.

BKK → TYO, answered.
Is $337 a good price for Bangkok to Tokyo?
Only slightly. The seasonal median is around $405 round-trip and this fare is 17% under it, about $68. 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 Bangkok to Tokyo?
Across 10 months of cached-fare history, Sep comes out cheapest on this route. The best months to actually be in Tokyo are Mar–May · Oct–Nov — when those overlap, that's your window.
How far in advance should I book BKK → Tokyo?
We do not publish a number for this, because we cannot measure it yet.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 10 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 Bangkok to Tokyo?
The current cheapest fares involve a connection, ticketed under Juneyao Airlines. 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.
