Gyoza is one of the popular dishes for Japanese and it has become recognized as popular Japanese dish in the world.
I just saw on a TV program that shows how Gyoza bar became popular in Paris. It was impressed that there is a line to wait get into the bar. People from kids to elder enjoy having gyoza at the bar.
Gyoza festival has been taking place until this weekend on November 26th. It takes 30 min from Shinjuku station to Tachikawa station by chuo line, and 10 min walk from Tachikawa station. The park is definitely beautiful of fall leaves.
Hope you enjoy the gyoza festival in gorgeous weather!
