It has been announced that the FUJI ROCK FESTIVAL '20, which was to be held for the 24th time this year, will be postponed to next year to prevent the spread of the COVID-19.
For those who have already purchased a ticket, it will be valid at next year's Fuji Rock Festival, so hold on to it. If you prefer to get a refund, details on how to proceed will be released soon.
It's a shame that hopes of the FUJI ROCK FESTIVAL '20 being held have disappeared, but let's hope that this situation will be resolved as soon as possible and we can all look forward to next year's Fuji Rock. I'm sure it'll be packed with two years' worth of energy.
