Cached-fare history: across 6 months, Sep is the cheapest for TYO → HAN. Best time to be there: Oct–Nov · Mar–Apr.
Fares bottom out in September around $309 and peak in February near $428 — a $119 spread across the 6 months we track. The cheapest itinerary we are tracking makes one stop and takes about 8 hours outbound, on a 6-night trip — ticketed under T'way Air, which on a connecting fare need not operate every leg. At $309 for 3,663 km each way, that works out to about $42 per 1,000 km flown. That is about the $39 typical of medium-haul fares here. Of the 3 departure cities we track at a similar distance from Hanoi, this is the cheapest right now — though Jakarta is within a few dollars.

Across 6 months of cached-fare history, Sep comes out cheapest on this route. The best months to actually be in Hanoi are Oct–Nov · Mar–Apr — when those overlap, that's your window.
How far in advance should I book TYO → Hanoi?
We do not publish a number for this, because we cannot measure it yet.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 6 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 Hanoi?
The current cheapest fares involve a connection, ticketed under T'way 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.
