TOKYO, Sept 9 (Reuters) - Japanese Finance Minister Yoshihiko Noda said on Thursday that monetary authorities are conducting various simulations on currency market intervention and will take decisive steps on the yen's rise when necessary.

Following are recent key quotes by Bank of Japan and government officials:

FINANCE MINISTER YOSHIHIKO NODA, Sept. 9, in parliament

(Asked how Japan would make currency intervention effective)

"I won't say anything specific on the matter but we are conducting various simulations."

BANK OF JAPAN GOVERNOR MASAAKI SHIRAKAWA, Sept. 9, in parliament

"The BOJ's monetary easing at the (Aug. 30) emergency meeting was not aimed at currency and stock market volatility."

NODA, Sept. 8, in parliament

"Basically it's important to closely communicate with the international community and we are currently making efforts on this. In the end, we will take decisive measures including intervention when needed."

SHIRAKAWA, Sept. 8, in parliament

"I am closely communicating with my G20 counterparts at both individual and multilateral levels.

"We are poised to take additional steps if the economy turns worse than expected and downside economic risks become visible."

SHIRAKAWA, Sept. 7, in news conference

"Currency rates fluctuate on a daily basis due to various factors. It is not appropriate to determine if our policy actions were a success or not by short-term market moves alone.

"We are fully aware that export-related companies are considerably affected by the yen's recent rise.

"But monetary authorities are unable to control currency rates freely ... We are carefully watching how the yen's rise impacts the Japanese economy."

NODA, Sept. 4, in TV show

"What they (Prime Minister Naoto Kan and ruling party leadership candidate Ichiro Ozawa) have been saying means the same thing. The issue is whether we would actually decide to intervene in the end.

"Our statement that we will take decisive steps when needed says it all."

PRIME MINISTER NAOTO KAN, Sept. 2, in ruling party debate

"As (Federal Reserve Chairman Ben) Bernanke said, the U.S. economy has not recovered as much as had been hoped, and in a way the dollar's weakness is behind the yen's rise."

He said he had had a sense of crisis about the yen's rise for some time and so the Bank of Japan and the government acted together on policy.

DEPUTY FINANCE MINISTER MOTOHISA IKEDA, Aug. 31, in symposium

"Currency intervention is the prerogative of the Ministry of Finance and the BOJ is its agent ... It would be no good if the BOJ absorbs money from the market in such a case and I'd want the BOJ to carry out unsterilised (intervention)."

He said the central bank should not rule out cutting its policy rate to zero from the current 0.1 percent in case unsterilised intervention was carried out.

NODA, Aug. 31, to reporters

"I appreciate that the BOJ responded appropriately and swiftly to underlying changes in the economic and financial situation ... I expect government (stimulus) steps, coupled with the BOJ's monetary policy, to have an effect from now on.

"Current moves in currencies are one-sided. Excessive and disorderly moves in the currency market could badly affect economic and financial stability. From this standpoint, I'll closely watch market moves with great interest and take decisive steps when necessary."

SHIRAKAWA, Aug. 30, in news conference

"The BOJ will act appropriately and in a timely manner, taking into account economic and price developments as well as changes in market moves.

"There are risks to the outlook, so we cannot rule out revising down our economic scenario in the future." (Reporting by Rie Ishiguro; Editing by Michael Watson)
