## Career
### Juniors

As a junior Uchiyama compiled a win–loss record of 99–61 (and 77–56 in doubles), reaching as high as No. 12 in the combined world rankings in March 2010. He reached the final of the 2009 Australian Open Boys' Doubles with Mikhail Biryukov, losing to Francis Casey Alcantara and Hsieh Cheng-peng in the final.

### 2013-2015

Uchiyama made his Davis Cup debut for Japan in February 2013, in the Asia/Oceania Zone Group I first round against Indonesia in Tokyo. In the 2014 Davis Cup World Group first round against Canada in Tokyo, he played the doubles rubber with partner Kei Nishikori, winning over Canadian pair Daniel Nestor and Frank Dancevic. Japan defeated Canada 4–1 to advance to the quarterfinals in the World Group for the first time ever.
He reached the final of the Lexington Challenger in August 2015, losing to John Millman in three sets.

### 2019: Best season: Major debut at Wimbledon , two ATP quarterfinals and Top 100

He qualified on his seventh attempt at the 2019 Japan Open, his home tournament, and reached his second ATP Tour quarterfinal (after 2019 Brisbane) with wins over Benoît Paire and Radu Albot. As a result, he reached the top 100 at world No. 87 on 21 October 2019.

### 2024: Sixth Challenger, third ATP quarterfinal, back to top 150

Uchiyama won his sixth Challenger at the 2024 Busan Open. Ranked No. 160 at the 2024 Hangzhou Open, he reached the main draw as a qualifier, and then defeated lucky loser James McCabe and upset top seed Holger Rune, for his second top 20 and joint biggest career win (with world No. 14 Kyle Edmund win in 2019 Brisbane), to reach his third ATP Tour quarterfinal (after Brisbane and Tokyo in 2019).
