Arrangements are being made for Tokyo Gov. Yuriko Koike to meet with International Olympic Committee President Thomas Bach on Oct. 18 when the latter is scheduled to be in Japan, a source said Sunday.

Koike is currently considering making changes to some already-decided competition venues for the 2020 Tokyo Olympics and Paralympics as part of cost-cutting measures, moves that would require the approval of the IOC.

A panel set up by Koike reported late last month that plans to build new venues for swimming, volleyball and rowing/canoe sprint should be reconsidered, with an option being using other existing facilities.

Based on the panel's report, Koike is expected to compile her plans over the venues around the end of October.

As the Tokyo Olympic and Paralympic organizing committee is scheduled to present to the IOC its budget plan for the Games by the end of this year, any changes in venue plans would require recalculation of expenses to be incurred.

Koike is expected to discuss with Bach her plans for the venues and the prospect that the costs to organize the 2020 Games may possibly soar past ¥3 trillion, the source said.

Bach is scheduled to visit Tokyo to attend the World Forum and Sports and Culture, where he will give an address at a session on Oct. 20.
