Tokyo Gov. Yuriko Koike announced Friday that she will stick with the original plan to build Ariake Arena, the planned volleyball venue for the 2020 Olympics, but at a significantly reduced price.

Ariake Arena was among three projects under review, along with the new aquatics center and the maritime venue for the rowing and canoeing competitions.

Koike said at her regular news conference at City Hall that the metro government managed to curb construction costs for the three venues in question by some ¥40 billion.
