The “Omotesando/Harajuku Hello Halloween Pumpkin Parade” is the “cute” alternative to the Kawasaki Halloween Parade targeted at kids. It takes place from 2pm-3:15pm.
If you’ve got kids under 12, you can apply for them to be part of the parade. In addition to costumed kids and trick or treating at the stores in the area, there will almost certainly be a major celebrity or two taking part. Last year, (and the year before) it was kawaii sensation Kyary Pamyu Pamyu.
