Natural High

For a family-friendly spring escape from the city, this festival sure is hard to beat. Held in the forests of Yamanashi, around a 90-minute drive from Shinjuku, Natural High has been running on clean energy for a full decade now and combines camping and a laidback vibe with tunes courtesy of names like singer-songwriter Keiichi Sokabe, acoustic folk rockers Overground Acoustic Underground and instrumental foursome Nabowa. Look out for the tasty and healthy festival grub, too.
