It would be difficult to find any pedagogical story that is comparable to that of "jugyou kenkyuu" (or lesson study in English) that has been practised for over a century in Japan in isolation and became a method that was used worldwide in less than 10 years. Because of its uniqueness and its history, it is an irrefutable challenge to understand what it is really about, how its basic aspects such as "a lesson or teachers' knowledge and its development," the "culture of education," the "measurability of educational activities" and other main aspects of education are or can be conceptualised and in which ways these can travel in a globalised arena of education. In this article, we try to give answers to these and some other relevant issues related to lesson study via the author's subjective view and individually-constructed narrative.
