The beginning of December in Tokyo has begun full of miserable weather and messes on traffic. After an extraordinarily warm sunny day, cold rain covered and let flowers fallen on the ground. The center of Tokyo became a chaos due to system-down of the newly installed train-traffic-control software into the metropolitan main line. Finally, urban trains stopped by suicidal accidents. The remaining days of this year are less than one month. Toward the end of a year, Tokyo is so noisy as any large city is so felt.
