Kei had a fantastic run in Tokyo where he reached the final without dropping a single set. Kei will try to win the title in Tokyo for the 3rd time after he triumphed in 2012 and 2014.
Daniil had a more difficult run as he had to start from the qualifications. Eventually, the Russian reached the final after losing 1 set in 6 matches and following a great performance in the semifinals against Denis Shapovalov (6-3 6-3).
The favorite is Nishikori that has played fewer matches than Medvedev and he will have the full support of the local crowd.
The match will be played on Sunday at 3.30pm
