## Professional career
### 2007–12: First steps, first WTA Tour title in doubles

Aoyama made her ITF Women's Circuit debut in the doubles event at Gifu in 2007. In March 2009, she won her first ITF title at the $10k Kōfu doubles event. In June 2010, she won her first singles ITF title at Tokyo. In October 2010 at the Japan Women's Open, she made her WTA Tour main-draw debut. She failed to qualify in singles and had more success in doubles, reaching her first WTA Tour final. In late November 2010, she won the $75k Toyota doubles event. In June 2011, she made her WTA Tour singles debut at the Birmingham Classic as a qualifier. At the 2011 Wimbledon Championships, she made her major debut in doubles. At the 2012 Washington Open, she won her first career title in doubles. In September 2012 she won the $100k Ningbo Challenger. During the 2012 season, she also won two $50k events, the Lexington Challenger and the Bronx Open.

### 2013–16: More success in doubles, Wimbledon semifinalist

As time passed, Aoyama became mainly a doubles player, playing in doubles events preferentially to singles. She made a strong start into the 2013 season reaching the semifinal in the first week of January at the Shenzhen Open. Soon after, she won her first Grand Slam match at the Australian Open, but then lost in the second round playing with Irina Falconi. In March, she won the Malaysian Open with Chang Kai-chen. She also had a strong start into the grass-court season, reaching the semifinals at the Rosmalen Championships. She achieved more success at Wimbledon, when she and Chanelle Scheepers reached semifinals. This was her first significant Grand Slam result. In the semifinal match, they lost to Hsieh Su-wei and Peng Shuai. In September, she won the Washington Open for the second year in a row. At the end of the year, she reached semifinals of the Korea Open and won the Toyota World Challenge.
During the next three seasons she did not have as good performances as in the 2013 season. In 2014, in singles, her only significant result came at the end of the year, when she reached the final of the Toyota World Challenge but lost to An-Sophie Mestach. In doubles, she won the Washington Open for the third year in a row, and later in October, she won the Japan Women's Open. During the year, she also had success on the ITF Women's Circuit. In May, she won the $50k Fukuoka International with Eri Hozumi, and later finished as runner-up at both the $50k Lexington Challenger and the $75k Toyota World Challenge. In the first week of the 2015 season, she reached the final at the Auckland Open with Renata Voráčová, they lost to Sara Errani and Roberta Vinci. A month later, she reached the final of the Thailand Open with Tamarine Tanasugarn. She then did not have significant results until September, before she reached semifinals at the Korea Open, and later winning two $100k events, in Nanjing and Tokyo. During 2016, she won one WTA doubles title at the Japan Women's Open, and finished runner-up at the Nuremberg Cup, Washington Open and Jiangxi International Open. She also won three $50k events, in Quanzhou, Shenzhen and Wuhan.

### 2019–20: New partnership, French Open quarterfinalist

She reached the 2020 French Open quarterfinals, partnering compatriot Ena Shibahara.

### 2021: Miami Open & four more titles, Olympics & top 5 debut, WTA Finals semifinalist

She reached the 2021 WTA Finals semifinals, also partnering Ena Shibahara.

### 2022: World No. 4, Australian Open semifinal

Aoyama continued the partnership with Shibihara for the tournaments at the beginning of the year in Australia. At the Australian Open, they improved on their quarterfinal result the previous year by reaching the semifinal. Following this result, Aoyama reached her highest doubles ranking of world No. 4, on 28 February 2022.
For the three other majors during the year Aoyama partnered with Chan Hao-ching, reaching the quarterfinal stage at Wimbledon, and the third round at the US Open (losing to the eventual winners Krejčíková and Siniaková).
Her final competition was at the Billie Jean King Cup where Aoyama partnered with Shibahara once again. They won each of the six doubles matches they played.

### 2023: Australian Open finalist, 30th tour final, Canadian champion, back to top 10

At the Australian Open, she reached the finals of a major for the fourth time in her career, again with Shibahara. The pair defeated second-seeded pair of Americans Coco Gauff and Jessica Pegula in the semifinal to reach their first major final. However, they were defeated in straight sets by defending champions Krejčíková and Siniaková.
She won her 18th title at the Rosmalen Open and the WTA 1000 title at the Canadian Open, partnering Shibahara.
The pair qualified for the 2023 WTA Finals for the second time. Aoyama returned to the top 10 on 23 October 2023.

### 2024: Pan Pacific Open doubles title

Partnering with Eri Hozumi, Aoyama won the doubles title at the Pan Pacific Open, defeating Ena Shibahara and Laura Siegemund in the final. The pair were runners-up at the Hong Kong Open, losing to Ulrikke Eikeri and Makoto Ninomiya in the final which went to a deciding champions tiebreak.
