Finance Minister Masajuro Shiokawa said Tuesday that the rapid decline of the dollar must be checked before it reaches the 115 yen level.
"Since there is a (pessimistic dollar) tendency, we must prevent the dollar from reaching that level by all means," Shiokawa told a regular news conference.
Shiokawa made a similar remark on exchange rates last week, inviting speculation that the Japanese government would tolerate the dollar falling to the 115 yen level.
