Turkey beat South Korea to ensure a top-four finish ©Volleyball World

Japan and Turkey booked their places in the last four of the women's Volleyball Nations League (VVL) with victories in the penultimate set of round-robin games in Rimini.

Both needed one win form their last two games to be guaranteed a top-four finish, and did the business today with four-set wins.

Japan overcame Germany 25-23, 19-25, 26-24, 25-15.

Turkey later beat South Korea 25-23, 20-25, 25-17, 25-18.

For Turkey, the win avoids them needing a positive result versus second-place Brazil tomorrow.

"We are very proud," Turkey's Cansu Özbay told Volleyball World.

"It was an important victory for us. 

"Now we will play in the Final Four, but the round-robin is not over yet, as we have one more game together against Brazil. 

"It was difficult to play against Korea, because they have many great players - it was a very tough game mentally and physically, but we did a good job and I am really proud of my team."

The United States beat Russia in four sets to remain undefeated in this season's VNL and will finish the round-robin top of the bunch, while Brazil - now guaranteed to come second - beat the Dutch 25-19, 25-19, 25-20.

This season's VNL is being played in a bubble in Rimini, and after tomorrow's concluding round-robin matches, the women's semi-finals are scheduled for June 24.
