Today is Obon, an important Japanese holiday. Traditionally it is a day for honouring the spirits of one’s ancestors. But since the Japanese never pass up an opportunity to have a party, it is also an excellent reason to organise a festival and get together with friends and family.
Apart from delicious festival food and lots of people wearing yukata, the Obon festival is characterized by Obon dances, which are called Bon Odori (ηθΈγ). The dancers gather around a central stage and perform circular dances while moving around the stage. Compared to some Western dances, the Obon dances seem very slow and subdued. But once you give it a try, it is a wonderful feeling to share in the group atmosphere and to do the dances together.

Anyone can join in: there are many elderly ladies, but also lots of young people. Even clumsy gaijin like me are welcome to join. In the video below you can see the cutest little boy doing his best to dance along with the adults. There is also an equally cute, but slightly older girl in yukata.
In this next video you get a better look at the crowd and you can really see the circular motion of the dancers. Sometimes you will see ladies in matching yukata. I think they belong to an Obon dance group where they practice all year long and then go to various Obon festivals in their matching yukata.
There are big Obon events like the one at Nagoya Castle where these videos were made but Obon is also celebrated on a smaller scale in local neighbourhoods. When we were wandering around Muroran, a small city in Hokkaido, on an evening in August, we saw this local Obon gathering on a neighbourhood square:
