On our last day in Tokyo, we visited the Tsujiki Fish Market, the largest fish market in the world. As it was the day after our Fuji hike, we didn't arrive early enough to see the auction in the morning, but the wholesale market was still impressive to see.
There were endless vendors with all kinds of seafood for sale, and although the activity from the early morning had slowed, it still bustled with deliveries being picked up on bicycle, on foot and machines whizzing by - you had to pay attention not to get run over!
After the fish market, we headed to the Electronics District to look around.
And in the evening, we went to Shibuya, where the busiest intersection in the world (for foot traffic) is located. It's a busy area for nightlife and shopping as well.
Here are a couple videos of the intersection - watching people cross from above, and when we crossed:
