TOKYO, Jan 14 (Reuters) - Japan will take appropriate action against excessive currency moves without excluding any options, Finance Minister Satsuki Katayama said on Wednesday, as the yen sank to its weakest level in a year-and-a-half.
Katayama was speaking to reporters in Tokyo after the yen slipped as much as 0.2% to 159.45 yen per dollar JPY=.
