About this Site and Myself

Hi. I am Nagai Tosiya (Tosiya is my personal name and Nagai is my family name). I was born in Japan in 1965 and now engage in education and writing. My chief concern is systemics and I created this website to publish the study in systems.

I usually write in Japanese, but I write in English as well. I can understand German and French as well as Japanese and English, but please post your comments in English to this blog.

Here is my photo.
