Yes, you read right.
On April 13th there will be a Parade/Event in Kichijoji & Inokashira Park.
Parade(Cosplay incl.) starts at 12:30 till 14:00.
On the northside(rotunda) will be a 8m Meter 1/1 Replica of a Patlabor, I think it will be the prop from the upcoming life-action movie.

Worthwhile a visit methinks.
