How do you teach a language to someone who cannot look at a page? The Michel Thomas method answers by removing the page altogether: no writing, no memorising, no homework, simply a teacher, two students and a listener invited to reason alongside them. Helen Gilhooly teaches Japanese squarely within that tradition.
The approach asks something particular of the teacher. Every step must be small enough to be worked out rather than recalled, and the sequence has to build so that the learner is constructing sentences before noticing any rules have been learnt. Foundation Japanese is the beginner stage of that programme, pitched at absolute newcomers rather than at anyone brushing up.
