Currently I am using Genki: An intergrated course in elementary Japanese. I am currently at chapter 6 and I am worried about some things that it is teaching me.

Even though the book is written by native speakers (two of which are professors at Kansai Gaidai) there seems to be apparently some mistakes in it.

Some pointed out to my Nagoyankee on this forum such as the misuse of 時 where it should have been ころ. As well as other things such as the apparently strangeness of saying じゃありません instead of ではありません.

Also in a review I read someone says that his wife who was a native speaker pointed out some problems when the book get's to the informal parts, apparently teaching some things which are too informal (to the point where they could be rude) as well as some things that native speakers would never say.

However of course that review is second hand information and a lot of people rave about how good the textbook is and I certainly think that it is easy to use. What is everyone's opinion on this book.

I was thinking of possibly switching to みんあの日本語(minna no nihongo/Everyone's Japanese) since it seems to have a very good reputation as a university textbook and there are setence structure practise books available to go with it. I am willing to splash out the cash to buy the book, it's translation and grammatical notes as well as the extras such as the kanji and sentence workbooks if people think it is definetely worth going for. What's is your opinion on this textbook?

Thanks for any help. I just want to be sure I'm learning things correctly.
