Until 26th December 2010, there is a fantastic display of china woodblock printed lanterns in Ueno Park, Tokyo. According to the website there are 165 of these lanterns, there did certainly seem to be a lot! It says on the website that they are lit up between 6pm and 9pm, but I think actually that they are lit when it gets dark because I was there earlier.
It really is well worth a look, I was very impressed! They're easy to find, just come out of the Park Exit of Ueno Station and walk into the park. The lanterns follow the main path, with some off to the sides. More pictures (not 165!) at the right-hand link.
