On October 19, I looked into "Betara City".
On page 168 of Monoshiri Encyclopedia, there was a tradition that Ebisu-ko was held on October 20 at the gate of Takarada Ebisu Shrine in Otemmacho during the Edo period. ・・ ・ ・ On the 19th the day before, there was a market selling offering. ・・ ・ One day, radish pickles began to be sold in the city. ・... The store also called in customers with a lively shout, "Betara, Betara," and explained that the city on the day before Ebisu-ko came to be called "Betara City".
portable shrine was out, too.
