Belated, at the age of 65, I received PhD from the Graduate School of Asia-Pacific Studies (GSAPS) of Waseda Univ.. It was the moment of a sort of 感動 (emotion) and a big 感謝 (appreciation). The title of my dissertation is “Dissimilation & Integration” through Parasports of People with Mild Intellectual Disability”/ 軽度知的障がい者のパラスポーツを通じた「異化&統合」の可能性について” building upon my experience of working with para-table tennis players. I wish I can revisit the countries I served before and interact more with young generations.
