This is the Japanese version of Nihongo, the book about the Japanese language which was originally published in English. We decided to launch the Japanese version for Japanese learners. We believe that readers will be able to follow the contents with a little help from their dictionaries. Please challenge yourself and enjoy them together with the English version. * ONE PIECE 32 !
