The 62 reference lessons are written in your language too. A bonus edition, entirely in your language. If you would rather have the whole card in Japanese, Simplified Chinese, Russian or Spanish, it is there. It comes with compromises: the spoken word stays English and there is no audio beyond it, and it carries no…
