The latest edition of this popular Japanese course for beginners has been completely rewritten to make learning the language easier and more enjoyable than ever before.
I’d only recommend if you’re looking to only speak and listen to Japanese. I wouldn’t recommend if you’re also interested in reading and writing Japanese, unless it’s alongside other resources which use kana and kanji
Best read when you have a stronger base knowledge of the language. If serious on learning the language, find a book that teaches kana as this only covers the spoken language. Wouldn't be my first choice in learning the language but will definitely go back when I learn kana.
I initially started this in 2009, when I started learning Japanese for the first time. Even then I thought it was nicely structured, if somewhat succint, so it's way easier going through it now when starting from a stronger base.
