In Japan, this is the season for illumination, or night time light displays. In the US, I would call this "Christmas Lights", but in Japan they are called Illuminations.
This year, I don't know if there will be illumination displays or not. They often bring crowds of people to see them, so maybe they will not be held this year because of the spread of coronavirus in crowds. I don't know. I do know I'm not going to see any illuminations. I've taken a look back at a few I've seen in the past.
