A new publication 『 100万回ネイティブが使っている 英会話決まり文句 』will hit the bookstores at the end of March. In it, you will find phrases commonly used by native speakers of English, but are usually unknown to Japanese speakers of English.
UPDATE: What a surprise to see Newsweek (June 2015) pick up this book in their「旬」section! I'm humbled.
