​Welcome to Arco Iris Lingua Square

Arco Iris [ar ko 'i ris] Lingua Square is a language school that specializes in language-coaching through reading along with some classes taught for particular objectives, such as preparation for TOEIC or working on weaknesses.  Our class focuses are EFL (English as a Foreign Language) and also mother-language skills (only English and Spanish at the moment). We aim to be a school offering an environment of easy language acquisition and progress for anybody who wants to learn.  
Arco Iris Lingua Square is a small school in Osaka, Japan, grounded on the principle of social enterprise.  It is dedicated to offering accessible quality language lessons to the masses and to the children in order to alleviate educational inequality.  We also pay attention to the importance of learning one's mother-language.  It is very important for children with multi-cultural or non-Japanese background to maintain such proficiency for securing their identity, future, or even daily communication.  Our school offers classes (English and Spanish reading at this point) whereby children can maintain or advance their mother-language skill at their own pace.  We also aim to simply offer children an easy, accessible, and comfortable place to be and study.
Regardless of styles, reading has always given us tremendous amounts of knowledge, hints of creativity, and open doors to imagination.  Reading teaches a lot, and leaves a lot in us.  This applies especially to books read in our childhoods.  Children learn and feel a lot as they grow up, and the books they read are no exception in nurturing their creativity and thoughts.  At Arco Iris Lingua Square, we have a large volume of graded readers in English and Spanish.  We are still working on expanding our library.  Children can pick a book of their choice that fits their level, cultivate their language skills while they learn many other things, and advance as they are ready. This is studying while having fun, and after all, that's got to be the best way to learn.    
As a language school, we are aware of the differences in language acquisition needs in children. Children with multicultural or non-Japanese background need an environment where they can keep and raise their proficiency so that their fluency is enough in each language community and gets them even higher (e.g. academic level).  Arco Iris Lingua Square offers such a place where children can grow their language skills in their own ways toward such goals.    
Being accessible is another matter that we aim to achieve, so that anybody who would like to learn can come here and do so.  We keep our prices reasonable.  A financial aid program will be implemented in the near-future.  Also, we are currently in the process of applying for a lesson-tuition-cover program ('Cram School Charge Promotion Services') run by Osaka city.               
Language learning, which can be frustrating sometimes, can be wonderful with the right kind of help.  Our main staff are experienced EFL teachers (Chung Kyungsuk and Yoko Kitagawa) with profound backgrounds, and we will soon have teachers for special-purpose classes who are as enthusiastic about teaching as we are.

EFL-Teaching experience in a variety of schools since 1979: Many children and adults are not yet exposed to a rich English speaking environment where they can use practical English.  Gaining confidence through reading, we hope to nurture an understanding and appreciation of English not as a subject but as a tool for global communication.
