A Japanese version of this page is coming soon. We are currently hard at work on developing a software app for use on smartphones and tablet computers. This is a lengthy process, as we wish to build significant user interactivity into our digital titles and incorporate all of the audio and video materials, as well as the functionality found on our current DVDs. We are adopting a modular approach, so that users will be able to choose what they want to study at any given moment and download that content into the app. Be sure to check back later or register your interest using the form below.
