We've scanned every flight from Riga to Tokyo to find the best deals. If you want a cheap flight, it's best to be as flexible as you can on dates. If that day's no good for you, try searching by month to see some alternative dates.
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 New Tokyo International Airport, it's worth checking your other options.
You can expect accommodation prices to be higher at this time of year too. Last-minute deals do crop up, but it's best to book everything in advance to avoid disappointment.
