Tokyo Toyko? Like Tokyo Tokyo in Tokyo?

I went to Tokyo the other day. Although I was pretty sure I was already in Tokyo, so I'm not sure if this is like central Toyko or what. :\

We were here to see the imperial palace (or the grounds, whatever we had access to really), but it turns out they close on Mondays and Fridays, so we just got to look at the perimeter. So that was a pretty scenic 8km.

My battery died just after that last picture, which pissed me off to no end because just after that I saw hummingbirds! I didn't know they had hummingbirds here, I thought they just had a word for it 'cause they exist. :S

I'll come back here when the grounds are open (with spare batteries too) so I can get some proper pictures.
