You can go dancing on Sundays!
Located just beside Yoyogi Park entrance (actually, very close to the cosplay area).
You can do the whole rock concert thing - head shaking, fist pumping action. Its really cute...
Or you can do the sweet little 60s dance
Or the more aggressive dance by leather-clad bikers with dubious hairdos.
You asked for it...
(there's a little surprise halfway...)
