Chris Broad. Abroad in Japan: Ten Years in the Land of the Rising Sun

 Enjoyable enough, despite the execrable pun in the title. At its best in the first few 'fish out of water' chapters, when the author is working as a teacher and trying to come to grips with Japanese culture. Once he finds fame as a youtuber it becomes less interesting, and it is more about how he can increase his subscribers/produce interesting content than Japan itself. I'll still be putting it in Helen's tsundoku pile given where she works.
