I worked for Ministry of Construction as an architect, 1956-1985.  Among the many buildings that I designed good or bad, the main gate (completed in 1969) of the National Diet (completed in 1936) may surely live much longer than I may.
I enjoyed learning French at L'Institut franco-japonais in Tokyo for some years around 15 years ago and learning English at NOVA English School in Aoba-ku Yokohama around 10 years ago.  Since several years ago, I was studying "Popular Song of Meiji Era" and I have just submitted the final draft of my thesis to the University of New England in Australia.
Now I wonder, "What shall I begin next?"
