The goal of this 13-lesson tutorial is to help the reader learn Japanese quickly and efficiently. The book covers the entire volume of grammatical, lexical and hieroglyphic material necessary for learning the language at the initial level. The material is presented as clearly and accessible as possible and is perfectly remembered thanks to a large number of visual diagrams, tables and examples with common vocabulary. To successfully consolidate the topic covered, exercises are placed at the end of each lesson, the keys to which are at the end of the book. The publication of the application is completed: a short dictionary and mnemonic cards. The manual is intended for a wide range of Japanese language learners, and primarily for those who have decided to master it on their own.
