"When should I buy plane tickets from Tokyo to Hanoi?"

Flights between Tokyo and Hanoi can be longer and more expensive, so consider using a secondary airport or connecting through another Asian city like Bangkok or Shanghai to reduce your overall travel time.

Look into budget airlines that operate between Tokyo and Hanoi, such as Vietnam Airlines or Jetstar. These airlines often offer lower fares, especially if you book early and travel light.
