Imperial Palace - East Gardens - Gymnasium

The one thing I found interesting in the Imperial Palace East Gardens was the gymnasium. I don't think it was open to the public, but the windows were open and we could hear major shouts and grunts. Initially, we thought it was a basketball match, but soon realised it was probably Kendo or Aikido or some other form of martial arts. By the sound of it, a good way to blow off steam!
