It was fine and rather warm today.
The ginkgo trees were yellow and beautiful.
In the morning I went to MLIT and in the afternoon I went to Marunouchi area to learn about underground space use.
There are many things I learned today. I often walk underground space, but I have never realized about the facilities which will be toilets when there happened in case of emergency such as earthquake.
It is a good season to see Christmas illumination there.
After work I visited Kitte to see my exｰboss of Expo 2005. It's been more than 10 years since we met. How fast time flies!
