It was about 10 a.m. on a recent morning when, riding my bicycle to work, I saw a man dressed as a horse and carrying a plastic bow and arrow gallop toward the Diet building. I stopped to watch. Tourists pointed and gawked. Two baton-wielding police ran over to rein the horse-man in.

Turns out, this real-life Sagittarius simply wanted his companion to snap a picture of him, which the police nervously allowed before shooing him away to other pastures.

Ahh, just another day in Nagatacho, where, since arriving in Japan in May for a one-year international affairs fellowship, I have been living in an six-story apartment complex just around the corner from Japan's political nerve center.
