'Rural', indeed. Since starting life in the mountains of Yamanashi in 2009, this self-styled underground dance party has emerged as a pint-sized progeny of the more established Labyrinth festival. Much like its most obvious spiritual forebear, Rural offers an alternative to Japan's major dance fests. There's only place for 1,500 eager fans, and the lineup – which includes the likes of Kompakt co-founder Wolfgang Voigt's ambient project Gas, California-based British producer ASC and Tokyo techno ever-present DJ Nobu – is an eclectic mix of artsy electronic music. This year's venue is the Uchiyama Farm campsite up in the mountains of Nagano's Saku city, a two-hour drive from Tokyo.
