A circle with a radius of 3.14 km drawn around the castle tower of Hamamatsu Castle✨
Hamamatsu Castle is known as the “Castle of Success” because many of the successive lords of the castle, including Tokugawa Ieyasu, later rose to become executives in the Edo Shogunate.
This course forms an equilateral circle with a radius of 3.14 km around the castle tower of Hamamatsu Castle. Since the course covers the entire Hamamatsu plain on the east side of Lake Hamana, there are no undulations to interrupt the shape except for Lake Sanaru, so you can draw a beautiful circle.
This is a good omen, so why not try it to pray for your success?
