Where can i obtaining news for currencies

You can get a lot of good information for free. Try the Analyst Arena section of BabyPips The Analyst Arena: Fundamental & Technical Analysis of Forex Markets which has news from DailyFX.

Major financial news websites such as Bloomberg, CNBC, FT.com, WSJ.com have currency related sections.

Other stuff: Nearly every financial website has an RSS feed and they separate their RSS feeds by topics. So you can search the site for the RSS feed related to markets, currencies, equities, regions, etc., and put it into an RSS feed aggregator. Google has a free one. This can be your own personal news feed. Or use Google Alerts that search news articles for keywords such as JPY, Yen, Bank of Japan, Tankan, etc. This may take a little bit of practice to filter out garbage alerts.

PS. Make sure you are using news.google.com and not google.com when searching for news.
