Good Music Party in Sarushima: 10 Summer Days, 13th Jul–7th Sep, 2019 tokyocheapo.com

What better place to hold a summer rave than an uninhabited island?
Known as Monkey Island, it’s the only natural island in Tokyo Bay and is a popular day trip destination.
Tickets for the final six days can be bought below in advance for ¥2,650.
Keep in mind that those with earlier numbered tickets will be given boarding priority for the boats back to Mikasa.
If you are planning on buying alchol at the event you will need your ID, however old (or young) you are.
