Castalia Co., Ltd. is pleased to announce that we have entirely renewed our official website today: 

In the midst of a major turning point of the era and the world, the “learning experiences” such as education, studying, workshops and training, are transforming themselves as well.  

Online and mobile learning will be valued more than ever in the future society. Castalia believes that our responsibility is to present people who need to learn, home and abroad, the tools to keep the learning experience going regardless of environment or circumstances.  

Upon launching our new official website, we focused on creating a simple and easy-to-use structure so that our customers can find at a glance the service that best suits their needs.  Another major change is that everything was built with Google Sites.  

We will continue to enhance our contents and present you with improved services.  Thank you for your kind attention and interest in Castalia.
