Rising Sun Rock Festival in Ezo 2014

You'd be surprised how many Tokyoites make the pilgrimage to Hokkaido for this two-day affair, where the main stage keeps going until dawn on the second night. The lineup at Rising Sun consists purely of domestic acts, with groups like Denki Groove, Unicorn and Sakanaction scheduled to appear this year. The festival is also a gastronomic delight: look out for stalls selling locally farmed produce, seafood and craft beer.
