DLF Place is hosting the second season of Konnichiwa Japan, a cultural fest that will showcase the best of Japanese art, culture and food. One of the star attractions of this two-day festival will be the sumo-wrestling competition. Wrestlers will be flown down all the way from Japan, so expect nothing but an authentic Japanese experience.
Ikebana tutorials (Japanese art of flower arrangement), origami and calligraphy workshops, choral Japanese singing with drums and Kimono-wearing experiences are some of the other things you should look forward to.
Also, get those costumes out as there'll be cosplayers all around (photo-ops, yay!).
