I went to Kawasaki to watch Kawasaki Halloween Parade. It was very fun event but some spectators entered road that was prohibited to pass. I felt organizer should hire security personnel. They had "Dog Halloween Parade" last Sunday. I also wanted to see dog parade.
As for lunch, I ate ramen at "Nanttsu-tei" If you like tonkotsu ramen, maybe you like black soup taste. (Link site is Japanese only).
