There are seven airlines offering flights to Tokyo. The most direct route isn’t necessarily the cheapest – being flexible is key to finding the lowest airfare rates. For example, try searching by month to see the best time of the week to fly. The cheapest date is currently 25 / May / 2019.
You can use the filters on your search to see more flights and find cheaper rates – Tokyo has more than one airport. So if you don't need to fly into Tokyo Haneda International Airport, it's worth checking your other options. The 1210 km flight usually takes about 5 hrs 40 mins.
23 flights go to or via Tokyo every week. Currently, the cheapest price available is £246. The most popular airline is Japan Airlines but do spend some time checking all your options – they aren’t necessarily the cheapest airline to book with.
During this peak season, accommodation prices often increase too, so it's best to book early. Or you could keep your fingers crossed and hold out for a last-minute deal.
