I have been helping Michiko at Nacos with the practice of English for native Japanese speakers. I have begun to notice little things that I had never really noticed before or I guess just took for granted being a native English speaker, but the way that the mouth is put together and where the tongue is placed at the time can make a huge difference in the way the sound comes out. Some major differences and most difficult letters to pronouce are “R” and “L”. They can sound very similiar at times to me and I can get confused as to what someone is saying.
