Halloween and start of winter illuminations in Tokyo

We just celebrated Halloween, but Tokyo is already adorned for the winter holidays, because most of the winter illuminations are lit at the beginning of November. I already visited most of them during the previous years, but I still can't wait to see them again...

Where to go first? Today I went to Odaiba, where there's a double treat: The Halloween parties (see the gigantic Halloween pumpkin projected on the Fuji TV building), and the Odaiba winter illumination. And there's even a Christmas tree here, but more about this later...
