The 2018 WTA Calendar has been announced. Players will play 55 tournaments in 32 countries, and there are a few changes. The most important one is the WTA Tokyo International event that won't be played in the Japanese capital but it will move to Hiroshima.
As every year also in 2018 Rogers Cup will change its venue, from Toronto to Montreal, while Dubai and Doha events will switch category status each other: Doha becomes a Premier 5 event again, Dubai a Premier event. 2018 marks the 45th year since the WTA was founded by Billie Jean King in 1973.
Since then, the tour has grown to more than 2,500 athletes and $139 million in prize money at events around the globe. WTA Finals will still be played in Singapore and WTA Elite Trophy in Zhuhai, but by 2019 the venue will probably change.
By that year, as well as in the men's tour, tournaments' categories will be modified and the whole system will be reviewed in order to make tennis even more attractive. Here you can find full WTA Calendar.
