World No.1 Carlos Alcaraz is known for maintaining a busy schedule each year, and this week is the perfect example. Alcaraz just finished competing in the Laver Cup in San Francisco yesterday, and kicks off his campaign in the Japan Open (ATP 500 Tokyo) tomorrow.
Unfortunately for Alcaraz, the field is full of formidable opponents, and his one-seed will not save him from a very challenging draw. There is no first-round bye, and he must sprint through the tournament that lasts just a week.
Tournament organizers for the Japan Open officially unveiled the full draw this morning, and it spells a tough time for the six-time Grand Slam champion. Below is a round-by-round breakdown for Alcaraz.

Alcaraz will face unseeded, No.41 Sebastian Baez in the first round. From there, he will face either Alejandro Tabiloor or Zizou Bergs in the second round.
Alcaraz's competition immediately gets tough when he will likely face either eighth-seeded Frances Tiafoe, Brandon Nakashima, or Jordan Thompson in the quarterfinals.
Should Alcaraz advance to the semifinals, he could face either fourth-seeded Casper Ruud, seventh-seeded Denis Shapovalov, Damir Dzumhur, Jaume Munar, or Matteo Berrettini.

If Alcaraz makes it through his side of the bracket, the final could be a matchup against second-seeded Taylor Fritz, third-seeded Holger Rune, fifth-seeded Thomas Machac, sixth-seeded Ugo Humbert, or Jenson Brooksby.
A title in Tokyo would be huge for Alcaraz. Not only is the cash prize of $2.2 million great, but the 500 ranking points would help him in his race against Jannik Sinner, who is competing in the China Open in Beijing.
The Japan Open (called the Kinoshita Group Japan Open Tennis Championships for sponsorship purposes) is the longest-running ATP Tour tournament in Asia, first held in 1972.
