Japan Expo is a convention on Japanese popular culture – the largest of its kind in the world – taking place in Paris, France, although it has branched out into a partnership festival – Kultima – and expanded to include some European and US pop culture as well. It is held yearly at the beginning of July for four days in the Paris-Nord Villepinte Exhibition Center. The attendance has increased steadily over the years, with 2,400 visitors welcomed in the first edition in 1999 and more than 252,510 for the 2019 edition.
