Ja! International Festival of Literature and Art with Humour is a cultural event that aims to highlight the importance of humour -understood in the broadest sense of the term-, in the arts in general and especially in literature. The organisers understand and really work to reclaim the role of humour as an expression of intelligence, civilization and the joy of living.

The festival has been held at the beginning of autumn each year since 2010 in different locations in the city of Bilbao. It presents a programme of different activities where there is space for both reflection and fun. Conversations and round table discussions about a very wide range of subjects, and interviews with the most interesting and outstanding authors of the time are combined with performances, competitions and exhibitions.
