I was looking for a good intermediate textbook to continue my Japanese studies after finishing volumes 1 & 2 of Minna No Nihongo Shokyu. Unfortunately, this wasn't what I was looking for.
As often happens when you change from one course to another, you find yourself repeating certain points and encountering other points for the first time with no explanation. The book is aimed at students who are studying Japanese formally at a North American University and the language used reflects this and is very specific. There are also many role-playing exercises, not ideal for the self-studier.
In my opinion, the key grammar points are brushed over all too briefly with each section covering at least a dozen new grammar points illustrated with some bizarre and complex examples, my favourite being (this in section 2): "In the old days, there was a time when a dollar was worth 360 yen, but now it is worth about 105 yen. In other words, nowadays, with dollars in Japan you can buy only one third of what you used to be able to." Not the sort of structure I urgently need to master!
However, the biggest issue for me is that there are no answers! I have checked the resource website but this has not been updated, nor does it provide any answers. If you have a Japanese teacher who can check your asnwers and assist with the role-playing exercise this might be a good purchase. As for me, I'm waiting for the imminent Minna No Nihongo Chukyu Grammar notes, hopefully with answers!
