Shichi-Go-San (7-5-3) is a tradition of bring children aged three, five and seven to the shrine for a blessing -- and lots of picture taking. The tradition is observed on the nearest weekend to November 15. I went to the Meiji Jingu Shrine next to Harajuku and it was a beautiful sunny day.
A wedding procession at the shrine.
Yoyoji Park in the fall.
Christmas decorations at Omotesando Hills, a really fancy shopping center. Visitors can stand inside the decoration for a photo opp. The photo spot is a cool idea--I saw a similar one at Roppongi Hills.
National Art Center next to Nogizaka Station (near Roppongi Midtown). First time I checked it out and already it is one of my favorite buildings in Tokyo.
