"(A great deal better than Japanese for busy people series) Immerse yourself easily and at your own pace in beginner to lower intermediate Japanese, start learning essential kanji as well"
"A great way for people who have mastered basic Japanese to teach themselves more complex verb patterns/kanji and grammar, ideal for people finishing bk.1"
"A good book for beginners but not as useful for teaching yourself Japanese as Minna no Nihongo series, doesn't explain grammer, verb patterns or scenarios as comprehensively"
