Have you heard of the National Defense Academy of Japan?
It is located at Obaradai in Yokosuka and young men and women are studying and getting trained to be future Self-Defense Forces (SDF) officers. The school holds an anniversary festival every year and their 62nd anniversary will be celebrated on 8-9th of November this year. It's open to public.
They will have an athletic contest in which two teams pull against each other at opposite ends of a pole. It's the nationally famous event of the school. You can also watch a part of their regular training as one of the festival attraction. As the school overlooks the deep blue Tokyo Bay and has beautiful views of Mt. Fuji to the west, you might want to stop by to enjoy their unique atmosphere if you are in the area on that weekend!
