Whatcha doing prowling round there at night Stu...going Ninja swimming? Seriously, I know a lady who trained in the art of that and she can walk across Moat beds and scale castle walls etc. Thats not a joke. Lovely place and a well composed scene.
Oooh, ninja swimming! Looks like the perfect spot for it. My wife's grandmother lived in Hikone. Sleeply little place. Swarming with ninjas. Love the tiny top of the castle in the corner of photo.
