Japanese trade minister Banri Kaieda said on Tuesday that the Ministry of Finance and the Bank of Japan should consult and make an appropriate decision on intervening in the foreign exchange market, Jiji news agency reported.

Kaieda said that not only Japanese factors but also global ones, including debt problems in Europe and the United States, are causing the yen to strengthen, Jiji reported.

The dollar fell to a fresh four-month low versus the yen on Monday as U.S. lawmakers' delay in reaching a deal to raise the U.S. debt ceiling unsettled investors and fuelled demand for perceived safe-haven assets. (Editing by Chris Gallagher)
