Cached-fare history: across 8 months, Sep is the cheapest for TYO → BKK. Best time to be there: Nov–Feb.
Fares bottom out in September around $301 and peak in August near $549 — a $248 spread across the 8 months we track. The cheapest itinerary we are tracking makes one stop and takes about 8 hours outbound, on a 4-night trip — ticketed under Juneyao Airlines, which on a connecting fare need not operate every leg. At $301 for 4,599 km each way, that works out to about $33 per 1,000 km flown. That is below the $39 typical of medium-haul fares here. Across the 4 departure cities we track at a similar distance from Bangkok, this fare ranks 4th — 1.9× the $160 we hold from Seoul. It is also the cheapest of the 7 routes of similar length we watch out of Tokyo.

What is the cheapest month to fly from Tokyo to Bangkok?
Across 8 months of cached-fare history, Sep 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We do not publish a number for this, because we cannot measure it yet.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 8 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 Tokyo to Bangkok?
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.
