I went to crowded Atsuta Jingu (Atsuta Shrine, Nagoya city) on November 19. Atsuta Jingu has been one of the greatest centers of worship in Japan from ancient times.
On November 15, children dress themselves up in kimono and visit the shrine with their parents to have prayer services for Shichi-Go-San. You can see children dressing in beautiful kimono on almost every day of November in famous shrine.
