The tournament has a long history and is an important fixture on the WTA calendar, attracting some of the top female tennis players from around the world. It offers valuable ranking points and prize money to participants, making it a significant event for players looking to improve their rankings and earn rewards.

The Japan Women's Open is played on hard courts, which is a common surface for many tennis tournaments. The hard court surface provides a challenging yet fair playing field for the competitors.

The event was held in women-only form for the first time in 2009, and was the second tournament of the season held in Japan: the Pan Pacific Open, a Premier 5 tournament, was held two weeks before. In 2015, the event was moved from Osaka to Tokyo and in 2018 to Hiroshima, before returning to Osaka in 2022. 

Past winners include Australian Samantha Stosur, who won 3 finals, and Hsieh Su-wei from Chinese Taipei.

The All-Japan Championships was first established in 1915 as a men's only tournament. In 1924, a women's event was added to the programme. The tournament has been mainly played in Tokyo throughout its long run but has also been staged in other cities such as Osaka in 1933, 1935, 1937, 1939.

Following World War II, the event was also known as the Japan International Championships up to the late 1960s. From 1979 until 2008, the Japan Open was a joint tournament for both men and women. This is no longer the case in the aftermath of the Ariake Coliseum hosting another women's professional tournament, the Pan Pacific Open. 

Prior to the reorganization of the men's event with the advent of ATP Tour, the Japan Open was known as the Tokyo Outdoor Grand Prix and was part of the Grand Prix tennis tour between 1973 and 1989.

Stefan Edberg is the tournament's record holder winning it 4 times: 1987, 1989, 1990 and 1991. After the Swede, home player Kei Nishikori managed to win the Japan Open twice.
