Marugoto: Japanese Language and Culture, published by Sanshusha Publishing in Tokyo, is a textbook based on the JF Standard for Japanese Language Education, providing both language skills and knowledge about the culture. The target audience includes learners without prior knowledge at universities, adult education centers, and other educational institutions.

The learning objectives include communicative competence in everyday situations, active language use, and the ability to read and translate texts of general content. Additionally, solid grammar knowledge at the A1 level of the European Framework is aimed for.

With the goal of particularly deepening writing, vocabulary, and grammar skills, "Rikai," the coursebook for communicative language competence, assists those who already have basic knowledge and wish to systematically expand their understanding of the structure of the Japanese language.
