“Ocean Peoples” is a festival for people who love the ocean, according to the organisers—held in the ocean-less Yoyogi Park Events Area. In any case, the event promises to offer beach food, a beach market with about 70 stalls, and beach music (whatever that is). Runs from 11am until 8pm both days.
Event details are taken from official sources whenever possible. It is always prudent to check the official event website before attending to make sure that there have not been any changes. If you know of an error in the calendar, then please let me know through the contact form.
