Through this campaign, the company aims to support learners of English in making their studies more fruitful. https://www.zkai.co.jp/books/sokutan7/endowataru6/ouen/ The 'Sokudoku Eitango' series, which has gained strong support from junior high and high school students and exam takers as a vocabulary book for acquiring practical English skills, and the long-selling 'Sokudoku Sokucho Eitango' series for adults, which builds 'one-stone-five-birds' ability, both employ a learning method that builds solid English skills through 'coherent text = context.' Professional soccer player Wataru Endo also used both series to hone the English skills necessary to compete on the world stage. This time, the company is implementing the 'Wataru Endo x Z Kai English Support Campaign' to support Endo's challenge on the world stage with English messages using phrases from both series, while also encouraging the 'power to communicate' of everyone studying English. The English messages that can be selected and posted within the campaign are all created using vocabulary and phrases featured in both series. By selecting and sharing an English support message for Endo, who is taking on the world, participants can experience how learning outcomes within a 'context' transform into 'practically usable English' as a passionate message. By cheering with words woven from the 'Sokudoku Eitango' and 'Sokudoku Sokucho Eitango' series, learning deepens. The company encourages participation in this campaign to make everyone's English learning even more fruitful through supporting Endo, who is active on the world stage.
