Misaki Doi (土居美咲, Doi Misaki, born 29 April 1991) is a Japanese professional tennis player. She is left-handed and uses a two-handed backhand. Her highest WTA singles ranking is 30, which she reached on 10 October 2016. Her career high in doubles is 78, which she reached on 6 October 2014.

Doi reached two junior grand slam doubles finals – at Wimbledon in 2007 with Kurumi Nara, and at the Australian Open in 2008, with Elena Bogdan (losing both). She is managed by Muse Group, a sports marketing agency based in Tokyo.

Junior career

Doi began playing tennis at the age of 3. She first distinguished herself in tennis as a middle-school student, reaching the semifinals of the All Japan Middle School Tennis Championships in both 2004 and 2006 and joining the ITF Junior Circuit in 2006. In 2007, while enrolled as a freshman in Sundai Kōei High School, Doi earned second place in the Japan Open Junior Championships in Nagoya.

A highlight of Doi's junior career was her successful doubles partnership with age-mate Kurumi Nara. They placed second in girls' doubles at the 2007 Wimbledon Championships, becoming only the second Japanese women's doubles pair to reach the finals of a Grand Slam juniors event since Yuka Yoshida and Hiroko Mochizuki at the 1993 US Open. Doi and Nara continued their run by advancing to the girls' doubles semifinals at a number of high-profile tournaments, such as the 2007 US Open and Wimbledon 2008. Doi also teamed with Romanian Elena Bogdan to place second in girls' doubles at the 2008 Australian Open. This flurry of successes catapulted Doi to No. 3 in Japan's under-18 tennis rankings for 2007; she had been recognized early on as one of Japan's rising stars in junior tennis.

2008 marked Doi's first participation in senior ITF circuit events. She partnered with Kurumi Nara again for the 2008 ITF event in Miyazaki, where they upset top-seeded sisters Erika and Yurika Sema 3–6, 6–3, [10–6] in the second round. Doi and Nara went on to triumph over Kimiko Date-Krumm and Tomoko Yonemura in the finals.

Professional career

2009

Doi officially turned pro in December 2008, at the age of 17. In 2009, her first full year as a professional, she focused primarily on Japanese tournaments, where she earned 2 first-place and 2 second-place finishes in singles and one second-place result in doubles. In October, she made her tour debut in the qualifiers of the HP Open, falling to American Abigail Spears in the second qualifying round. Doi was seeded 6th in the women's singles draw of November's All Japan Tennis Championships. She lost in straight sets to Akiko Morigami in the round of 16, 1–6, 2–6. Her performance in 2009's events lifted Doi from a year-opening ranking of No. 613 to a year-end mark of No. 199 and a place among the top 10 players in Japanese tennis.

2010

In 2010, Doi began playing professional tournaments outside Japan. She appeared in the women's singles qualifiers for that year's Australian Open. Doi then made appearances at several circuit tournaments, placing second in singles at Irapuato, Mexico in March. In doubles, she recorded three second-place finishes in as many weeks in April tournaments at Incheon, Gimhae, and Changwon, South Korea, with partner Junri Namigata. With new partner Kotomi Takahata, Doi won her first ITF tournament championship in doubles at the Fukuoka tournament in May, defeating Marina Erakovic of New Zealand and Russian Alexandra Panova in straight sets..

Doi's success continued in the qualifying rounds of the 2010 French Open, where she defeated Mandy Minella of Luxembourg and upset Michelle Larcher de Brito of Portugal 4–6, 6–4, 6–4 to reach the qualifier finals. With her victory over Russia's Vitalia Diatchenko, Doi had earned a spot in her first major tournament main draw, where she lost to Slovenian Polona Hercog in the first round. She finished the year with a first-place performance in the All Japan Tennis Championships women's singles.

2011

Doi's Grand Slam results improved in 2011, when she qualified for Wimbledon and had her first win in Grand Slam tournament against Bethanie Mattek-Sands (USA), 6–4, 5–7, 7–5. She went on to defeat Zheng Jie of China 6–3, 6–1 before losing in the third round to German Sabine Lisicki.

2012

The June 2012 Aegon Classic was Doi's first appearance in the quarterfinals of a singles tour event, which she reached by defeating No. 1 seed Francesca Schiavone of Italy 7–5, 6–4. Although Doi lost in that year's Wimbledon qualifiers to Frenchwoman Kristina Mladenovic, she received a lucky loser berth in the main tournament. Doi was defeated by her first-round opponent Arantxa Rus of the Netherlands.

After failing to qualify for the main draws of the US Open and Toray Pan Pacific Open, Doi found success at the HP Open, where she defeated Chanelle Scheepers of South Africa 2–6, 6–1, 6–3 to reach her first-ever tour semifinal.

2013

2013 marked the first year in which Doi qualified for all four Grand Slam tournaments. In the 2013 Australian Open, Doi punched her second-round ticket with a 6–3, 6–4 victory over Croatian Petra Martić before losing 6–0, 6–0 to Maria Sharapova. She had less success in the other Slams, losing in the first round in all three. At the French Open she faced Madison Keys of the USA; at Wimbledon, Spaniard Sílvia Soler Espinosa; and at the US Open, Petra Kvitová of the Czech Republic.

2016

At the Australian Open, Doi played seventh seed Angelique Kerber in the first round, winning the first set and holding a match point in the second-set tiebreaker before eventually losing in three sets. Kerber went on to win the title. On May 16 Doi achieved a new career high ranking of 38 in the world after a quarter final appearance in Rome. After Rome, Doi competed at the Aegon Classic, losing to Johanna Konta, 7-6 (7-3) 6-1. Doi reached the last 16 of Wimbledon 2016. She had wins over, Chirico, Pliskova and Friedsam before losing to Kerber 6-3, 6-1. She was the first Japanese player in the ladies draw to get to round 4 ten years.

Personal

Doi is coached by Christian Zahalka since April 2015. She uses a Srixon racquet and ASICS shoes, prefers to play on hard courts, and favors her forehand and serve. Her most admired players are Justine Henin and Shingo Kunieda. In her free time, Doi enjoys movies and listening to music. She lists her favorite foods as sushi and peaches. Doi has an active fanbase on social media, named the 'Doi Army.'
