His early professional years were spent honing his skills on the ITF Futures and ATP Challenger circuits. He captured his first Futures titles in 2016 and continued to build his ranking. A significant milestone came in 2018 when he made his ATP Tour debut at the Citi Open in Washington as a qualifier. Later that year, he recorded his first ATP main draw victory at the Rakuten Japan Open, defeating Robin Haase.
The following year, in 2019, Watanuki claimed his maiden ATP Challenger title in Kobe, a victory on home soil that was a testament to his growing capabilities. The subsequent years were a mix of steady progress and challenges. He reached his first ATP tournament quarterfinal as a lucky loser at the 2022 Lyon Open, where he secured his second career win over a top-50 player by defeating Pedro Martínez. This success was followed by a strong finish to the 2022 season, where he won back-to-back Challenger titles in Kobe and Yokkaichi, propelling him into the top 150 for the first time.
