Probably the most famous crossroads in the whole of Tokyo, right in front of Shibuya Station and the square with Hachikō's statue on it. If you look closely (click on the picture to open full view), you can see some of the aforementioned costumed people in the masses.
And if you manage to find me (I'm somewhere in there): Congratulations! You've got a better (or luckier) eye than me.

Interesting fact: The two red lines on the red light you can see are a measurement on how long it'll stay red (or green, with two green lines, when it switches). The smaller they get, the closer the light is to switching. Simple and quite useful, really.

Shibuya and one of the other signs of the Tokyo Motor Show. We left the station with just the right timing to catch a small parade of cars like this one. Not expecting it, we didn't get a lot of good photos, unfortunately.

In the lower observation decks of both Skytree and Tokyo Tower, there's glass floors. Impressive view down. And I was surprised to notice that at least in Tokyo Tower, the height didn't bother me at all.

Northward view from the Tokyo Tower to the Imperial Gardens and National Diet Building.

The Zōjō-ji as seen from Tokyo Tower. The area seems quite popular for holding marriages. With the hotel to the left offering special services in that regard. And we spotted at least one just married couple in the park to the right, getting their pictures taken. Passing down the road between hotel and temple, we could see part of the Unborn Children Garden with its many Jizō statues.
