博麗神社例大祭 (British:Annual Hakurei Shrine Grand Festival, Finnish: Varsinainen Hakurei Shrine Suuri Festivaali) is an event, since 2002, that takes place yearly around the globe in selected cities. It is a Touhou-only convention that takes place every spring and winter. In Japan only, Team Shanghai Alice also uses this event as to publicity release trail versions of new upcoming games before being released on the internet. Though the trial versions are translated and shipped to other cities beforehand so it's released there too.
