On 27 October, I had an opportunity to talk on onomatopoeia at Shimokitazawa Seitoku senior high school. 2 periods(100 minutes) are allotted for this special lecture, for the students (and teachers) of Global Education Course. As I am not a researcher on onomatopoeia nor a linguist, my lecture was focused on "the international understanding" making use of my experience. Here are (some of) the images that I prepared as a guide for the lecture. I thank all the participants for listening to me earnestly, I hope the non-native speakers of Japanese also enjoyed the time.
