Harajuku's Yoyogi Park is an excellent place to get a glimpse in person of all of those different sub-cultures you may have heard of. Rockabilly, Gothic Lolita, punk, hip-hop kids, you'll find them all here. You'll also find the locals having a picnic, practicing a play, watching a band, or eating some street food. It's a great chance to be a part of Tokyo culture without having to spend any money.

Near the entrance to the park, which is located just south of Harajuku Station, you might find different groups of Japanese men dressed as Elvis, dancing to his songs. They won't ask for money, they seem to love dancing and dressing up. You might also find groups of youngsters practicing their jump-roping skills. This isn't the jump-roping in America, these hip-hop kids have great skills and can do flips through the jump ropes, cartwheels, hand-offs, and jaw-dropping tricks for the fun of it.

Inside the park you may find a local band trying out their skills or dancers. There is also street food available. Generally, a box of noodles will cost around 400 yen. Feel free to take a rest and people-watch like the locals. Yoyogi Park is a great way to immerse yourself in different subcultures for free.
